Biotechnology provides novel chitosans

Chitosans are a promising class of biopolymers with many potential applications, but the chitosans commercially available today often do not fulfil the requirements for sensitive markets such as pharmaceutics or cosmetics. One problem lies in batch-to-batch differences typically observed with chitosans produced from shrimp shell chitin, a waste by-product of shrimp peeling factories. Also, the animal origin of these chitosans is sometimes considered as problematic. Therefore, the Nano3Bio consortium aims to produce well defined chitosans with known structures and functionalities through biotechnological approaches. The tools required for this approach come from nature itself, namely enzymes such as chitin synthase which produce chitin from small sugar molecules, and chitin deacetylases which convert chitin into chitosans. Work at the University of Münster, the co-ordinating partner of the Nano3Bio project, has now identified a number of genes from different organisms - bacteria, fungi, viruses, algae - that appear to code for chitin deacetylases. These genes were used to drive the biotechnological production of the enzymes they encode. The recombinant enzymes were then characterised and used for the biotechnological conversion of chitin into chitosan. Interestingly, the chitosans obtained differ in their fine structure from all currently available chitosans which invariably are produced from chitin using chemical methods. Clearly, the chemical process yields “simple” chitosans which differ from the more complex and more varied chitosans found in nature. Ongoing work in the Nano3Bio project aims to test the material properties as well as the biological activities of these novel, “third generation” chitosans.

First detailed life cycle assessment of chitosan production

The Nano3bio project has carried out the first detailed life cycle assessment (LCA) of chitosan production from crustacean shells, using data from two manufacturers in India and Germany. LCA assess the overall environmental impacts caused by a system of production, use, and disposal processes necessary to provide a specific product. The LCA study within Nano3Bio includes the production and processing of all involved raw materials (crustacean shells as a by-product from fisheries), production of materials and energy carriers (chemicals, fuels, electricity) used in the manufacturing process, and the disposal of waste generated in the process (solid waste and wastewater). Knowledge gained from this LCA will be used by the manufacturers to define strategies to reduce their environmental impacts, both in their directly controlled activities as well as in their supply chain. The results from this study will be submitted to the European LCA database ELCD, where they will be publicly available. Implementing LCA during research activities is an important approach within the Nano3Bio project in order to contribute to an overall sustainable development regarding the usage of raw organic materials.

Internalisation of chitosan nanocapsules into human cells

Drug administration to patients is frequently associated with adverse effects. This is especially relevant for therapies of cancer with chemotherapeutics leading to reduced life quality of the patient. Adverse effects are mostly related to the inefficient deliverance of drugs to the tumour and thus to systemic dissemination affecting the whole body. In the past, various strategies have been developed to improve tumour targeting and thus to minimize adverse effect. One of the most promising approaches is the encapsulation of therapeutics into particularly small sized carriers. The development of such carriers has been intensively followed in the last decades. Today, novel chitosan-based nanocapsules represent an achievement of the Nano3Bio consortium. The chitosan applied in this context is a fully degradable biopolymer preventing the accumulation of the capsules in the human body. The efficient uptake of the chitosan-nanocapsules into certain cells due to their unique physicochemical properties envisions an improved targeting of tumours and thus a reduction of adverse effects during cancer therapies. The University of Heidelberg (Germany) mainly carried out the research and development activities related to chitosan nanocapsules.

First microalgal chitosan isolated and identified

The research and development team of Greenaltech, a Nano3Bio partner company from Spain, has recently discovered the presence of natural chitosans in certain green microalgae species. With the help of other Nano3Bio consortium partners, Greenaltech is currently working on their characterization. The microalgal chitosans are completely natural sub-stances that do not suffer from any chemical modifications. Moreover, they are of non-animal origin, an important advantage in some industries from a regulatory and marketing perspective. Furthermore, the microalgal chitosan production process is fully controllable as it is performed in closed reactors from the inoculation of the culture media with microalgae to the last chitosan purification step. These advantages, together with the physico-chemical and bioactive properties that are still being elucidated within the Nano3Bio consortium, will be taken into account to select the niche markets in which the microalgal chitosans may have a higher potential of success.

Chitosan-based hand cream formulation developed

For the cosmetic sector, chitosans are especially interesting due to their antimicrobial and thickening properties. Besides other functions, they can be used as a multifunctional raw material covering the two requirements of microbial stability and viscosity control with just one ingredient. These two functions are determined by variable chitosan characteristics like the molecular size and the side chain distribution. To determine the ideal characteristics necessary for personal care products, the Nano3Bio partner company Cosphatec is testing different chitosan types provided by other consortium partners. By combining different chitosan types, Cosphatec is able to produce a cream formulation in which no other thickener is needed. At the same time, the antimicrobial stability is kept while reducing preservation significantly to a minimum of the usual concentration. Within upcoming research activities of Nano3Bio, it is even aimed to further optimise these results. So far, the heterogeneity of currently available chitosan was one of the main hurdles for establishing frequent usage of this raw material. A benefit of the ability to produce chitosan biotechnologically will be the possible control of the process achievable only through exact knowledge of the underlying biological mechanisms. In this way, Nano3Bio aims to manufacture mass tailored chitosan with properties fine tuned to the desired applications in order to satisfy the corresponding market demand with a reliable and reproducible quality.

Low-cost protein engineering technology developed

Synthetic biology researchers from academia and industry alike now have access to low-cost genetic material to help identify protein variants. Developed in part through research funding from the European Union’s Nano3Bio project, the GeneArt Strings DNA Libraries tool makes protein engineering, normally an expensive endeavor, attainable to cost-sensitive customers.

The new GeneArt Strings DNA Libraries is complementary to Thermo Fisher’s existing technology currently used for protein engineering by a process known as directed evolution. This method is designed to identify protein variants with improved properties such as enhanced function, better stability or properties that demonstrate novel enzymatic activity. Proteins engineered with enhanced enzymatic activity have many applications in daily life. As an example, enzymes found in many laundry detergents must be engineered to remain stable and active in hot, detergent-rich water, which are very different conditions compared to their natural environment.

The process of screening and engineering proteins is cost- and labor-intensive. The starting point is a DNA library – a collection of variants of the original DNA sequence encoding the protein of interest. These libraries contain thousands to billions of variants and serve to produce the protein variants that enter the screening procedure.

The expensive screening technology used to identify improved protein variants is compounded by the high cost associated with the meticulous process required to produce high-quality DNA libraries. However, research funded through the Nano3Bio project has enabled implementation of novel technologies and a production workflow to lower the cost of library production. Some of the first researchers to receive these new libraries are Nano3Bio consortium members from IQS in Barcelona, who are using them to develop enzyme variants that can produce novel chitosan oligomer types. The Nano3Bio project is funded by the European Union.

Protocol for production of chitosans with defined structures

In order to be able to explore the benefits of chitosans in depth, there is the need of obtaining it with a defined structure. In order to do so, one of Nano3Bio’s strategies is to combine enzymatic processes with chemical transformations. For this purpose, the project has dealt with the chemical activation of compounds for the in vitro preparation of controlled chitooligo-saccharide polymers (organic compounds formed by the repetitive linkage of small molecules called monomers) by certain (enzyme-catalyzed) reactions. Materials readily available from natural resources are transformed through chemical reactions into monomers designed to self-condense in a well-defined manner when reacting in the presence of an engineered enzyme. In order to obtain the desired monomers, specifically developed conditions are applied onto the starting materials followed by a treatment that allows the isolation of the product. Thus, other minor impurities that could be detrimental for the quality of the polymer or could even prevent the polymerization reaction are removed from the monomers. These reaction conditions developed during the project do not only allow the preparation of simple molecules, but also of structurally more complex compounds that may confer special properties to the polymers prepared from them. Enantia, a Nano3Bio partner company seated in Barcelona, mainly executed these activities.

Research on chitin and chitosans: Nano3Bio explains its approach via video clip (part 1/2)

Technology dependent industries like medicine, agriculture and cosmetics are continuously driving innovation for new materials and substances forward. Because of its unique properties, chitosans have become a promising candidate for research in these fields. Chitosans are abundant in nature but not yet marketable for high standard applications. In the Nano3Bio project, scientists and industry are collaborating to produce Chitosans with biotechnology. They aim to generate environmentally friendly, reliable and safe products for health care, food industry and cosmetic applications. The Nano3Bio consortium now released a video clip on the internet explaining its approach in just about five minutes. The film also contains some interviews of involved scientists.

The Nano3Bio researchers assume that many different fields of application will be found in which a specific chitosan can replace or support other substances. „Let us assume the Nano3Bio project will bring out tangible research and development results: In the foreseeable future chitosans will be much more common and improve existing technologies and possibly initiate new ones“, says the narrator in the Nano3Bio video clip. Chitosans are natural sugar compounds and closely related to Chitin, which is well known as the major component of insect and shellfish exoskeletons. And moreover it is found in the cell walls of all kinds of fungi. There is not only one Chitosan - there are many Chitosans. The consortium believes that this diversity in structures is also the reason for the diversity in biological activities. Chitosan is classified as bioactive, which means that living organism show all kinds of reactions in the presence of Chitosan. When biologists started exploring the bioactivity of Chitosans they revealed a variety of beneficial effects on plants and animals.

The film is available on the Nano3Bio website www.nano3bio.eu as well as on the project's channels on LinkedIn, Twitter, Facebook and Google+. A second video clip is going to follow soon.

Biotech research project Nano3Bio is running

'Huge Potential' through Biotechnology

While the oil is slowly but surely running out, renewable resources are becoming increasingly important. In future, the biological production of raw materials has to play an even greater role to meet the needs in an environmentally friendly manner. An international consortium of researchers and companies now rises to this challenge. Its goal is the biotechnological production of so-called chitosans, which are used as raw materials for medicine, agriculture, water treatment, cosmetics, paper and textile industries as well as many other fields of application.

To tap this potential, the European Commission supports the research project "Nano3Bio" with a total of almost 9 million Euros up to 2017. In addition to the experts from your organisation, universities and research institutes as well as companies from Belgium, Denmark, France, Germany, India, The Netherlands, Spain and Sweden are involved. They recently met to kick off the project in Münster, Germany.

"The Nano3Bio project is making a scientific dream come true, because this strong consortium will be able to achieve a breakthrough from basic research to the biotechnological production of chitosans", says Professor Dr. Bruno Moerschbacher, biologist at the University of Münster and coordinator of the project. So far, chitosans are typically obtained by chemical means from limited resources such as the shells of crabs and shrimps, or, rarely, from fungi or squid pens. Within the biotechnological process, specially prepared fungi, bacteria or algae are to take over the production of chitosans. One hope of the researchers is that this will be energy-saving, more environmentally friendly and less expensive than using current methods. But equally important is the replacement of chemical methods by biological ones which will lead to more natural and better defined chitosans than available today. Moerschbacher: "Succeeding would be a great achievement, including huge economic potential." But the road is challenging: For example, it is important to determine which biological organisms are able to produce exactly that quality of chitosan, which is required for a specific application.

The biochemical quality of chitosans is at least as diverse as their applications. For example, one specific chitosan is suitable for finishing seeds to protect them from pests and diseases, and to yield richer harvests. Another one is acting as anti-bacterial, film-forming agent in spray plaster accelerating scar-free wound healing. In medical applications, specific chitosans can ensure the transport of drugs to their target sites, e.g. in the brain or in cancer cells. Furthermore, the researchers assume that many other fields of application will be found in which a specific chitosan can replace or support other substances. For many applications, this is a highly promising prospect since one of the good qualities of chitosans lies in the fact that they are well tolerated by the human body and easily biodegradable in the environment.
