Bacillus megaterium is a bacterium that has been used for the industrial production of vitamin B12 (cobalamin), the anti-pernicious anaemia factor. Cobalamin is a modified tetrapyrrole with a cobalt ion coordinated within its macrocycle. Previous findings outline a potential way to develop B. megaterium as a cell factory for cobalamin production using cheap raw materials. In this paper, a novel strategy was implemented to investigate the possibility to use sunflower protein isolates and its enzymatic hydrolysates ...

The bioconversion of plant raw materials into highly added value products, as well as the development of new products with advanced characteristics has a high priority for modern biotechnology in the Russian Federation. Deproteinized sunflower meal has been used as a source of carbohydrates and organic nitrogen for the yeast S. cerevisiae fermentation after subsequent acidic and enzymatic treatment. As a result a protein-rich yeast biomass was formed, as well as a liquid fraction, containing non-metabolized pentos...
