Farming of Medicinal Mushrooms.

Adv Biochem Eng Biotechnol 2022 Apr 2. Epub 2022 Apr 2.

Faculty of Chemistry and Chemical Technology, University of Ljubljana, Ljubljana, Slovenia.

Since most of the medicinal mushrooms are rare in nature, production of fungal fruiting bodies is hardly covering the food market and the production of pharmaceutically active products, so artificial cultivation of fruiting bodies in a form of farming has been intensively established during the last 40 years. Various cultivation technologies are presented, including traditional farming of fruiting bodies on wood logs and beds, and also on other substrate-based media, such as cultivation in bags, bottles, and others. The advantage of farming is a cheap but time-consuming large-scale production. Read More

Microfluidics in Biotechnology: Overview and Status Quo.

Adv Biochem Eng Biotechnol 2022 Mar 26. Epub 2022 Mar 26.

Multiscale Bioengineering, Faculty of Technology, Bielefeld University, Bielefeld, Germany.

Microfluidics has emerged as a powerful tool, enabling biotechnological processes to be performed on a microscale where certain physical processes (such as laminar flow, surface-to-volume ratio, and surface interactions) become dominant factors. At the same time, volumes and assay times are also reduced in microscale - which can substantially lower experimental costs. A decade ago, most microfluidic systems were only used for proof-of-concept studies; today, a wide array of microfluidic systems have been deployed to tackle various biotechnological research questions - especially regarding the analysis, screening, and understanding of cellular systems.

Industrial Perspectives for (Microbial) Biosurfactants.

Adv Biochem Eng Biotechnol 2022 Mar 18. Epub 2022 Mar 18.

Bio Base Europe Pilot Plant, Ghent, Belgium.

Within the bio-economy, more specifically within the bio-based industries, biomass feedstock - in contrast to fossil feedstocks in the fossil-based economy - is converted into the so-called bio-based products such as biosurfactants, bioplastics, pharmaceuticals, paper, textiles, and biofuels using either chemical or biological production methods or a combination thereof. In Europe a turnover of 60 billion EUR is associated with bio-based plastics and chemicals such as biosurfactants, and 40% of the global biosurfactant market turnover is associated with the European market. The growing use of bio-based surfactants in detergents, personal care products, and oilfield chemicals is fueling the growth of this market, which is driven, in many applications, by more stringent regulations and by an increasing consumer demand for "green and sustainable" products.

Exploiting Aerobic Carboxydotrophic Bacteria for Industrial Biotechnology.

Adv Biochem Eng Biotechnol 2021 Dec 12. Epub 2021 Dec 12.

Microbial Biotechnology, Campus Straubing for Biotechnology and Sustainability, Technical University of Munich, Straubing, Germany.

Aerobic carboxydotrophic bacteria are a group of microorganisms which possess the unique trait to oxidize carbon monoxide (CO) as sole energy source with molecular oxygen (O) to produce carbon dioxide (CO) which subsequently is used for biomass formation via the Calvin-Benson-Bassham cycle. Moreover, most carboxydotrophs are also able to oxidize hydrogen (H) with hydrogenases to drive the reduction of carbon dioxide in the absence of CO. As several abundant industrial off-gases contain significant amounts of CO, CO, H as well as O, these bacteria come into focus for industrial application to produce chemicals and fuels from such gases in gas fermentation approaches.
