The biorefinery based on biotransformation by

Bacillus subtilis

of meal from oilseeds

The most effective holistic approach of circular economy based on biotransformation of the agricultural biomass, which has been

developed in the last few years, is the concept of biorefineries. In the biorefinery approach assuming zero waste, each process stream

is exploited to the full through careful fractionation to produce commercially valuable products or through reuse of byproducts

and wastes. The biorefinery approach has already been introduced to this area through a consideration of biodiesel and bioethanol,

but very interesting seems multitude of other application especially in green chemistry to obtain high value added compounds. The

main objective of the recent study is construction of demonstration plant focused on possibilities using GRAS microorganisms such

as

Bacillus subtilis

in biotransformation meal remaining after oil extraction from oilseeds and subsequent fractionation. The key to

this is the assertion that a complex mixed component material can be exploited in a variety of ways with some components used to

produced new materials while others can be directly fractionated and separated into commercially highly valuable materials. Most

of high value added products are synthesized in relatively low quantities e.g., biosurfactants making often the production process

unprofitable. Thus, after their extraction the remaining biomass must also have an increased value as an end product, which could be

complementary feed for animals as

Bacillus subtilis

var natto strains have probiotic properties. The realization of the demonstration

biorefinery requires multidisciplinary approach and development of several dedicatedmethods such as Solid State Fermentation (SSF),

fractionation using ecologically friendly solvents such as super critical carbon dioxide and centrifugal partition chromatography.

Biography

Marcin Lukaszewicz is working as an associate professor at the Department of Biotransformation, University of Wroclaw, Poland. He has has done research on the

optimization of lipopeptide biosurfactants production, methanogenesis and biocalcification. His research work also includes the model complexes agro-power as

an example of dispersed cogeneration based on local and renewable energy sources.
