Sažetak
Disaccharide cellobiose [beta (1-4) glycosidic bond] can be natively transported into the cell by Lactobacillus amylovorus DSM 20531T and fermented with high percent theoretical yield to lactic acid being the main end-product (unpublished results). Besides, experimentally has been shown that the wild-type of this strain also uses maltose [alpha (1-4) glycosidic bond] and, after hydrolysis, higher maltooligosaccharides (unpublished data). Utilization of later substrates also resulted in a highly efficient production of different ratios of D- and L-lactic acid at mild temperature and maintained pH value in a laboratory-scale stirred tank reactor (up to 20 L). Glucose repression in all above cases was not observed. Collected data serves as a sound basis to build on in collaboration with a scientific and/or industrial partner in order to implement this versatile wild-type biocatalyst with GRAS status and adapt it for possible industrial applications. We offer a co-development of a bioprocess for D-/L-lactic acid production that will be catalized by the wild-type lactic acid bacterium strain L. amylovorus DSM 20531T capable of fermenting unusual substrates such as cellobiose. In addition, metabolic flexibility of the strain should be explored in terms of using other unusual substrates, e.g. xylose. Introduction of xylose specific transporter and xylose pathway in the wild-type strain may result in creation of an robust and functional biocatalyst to be selected for cascade processing of renewable feedstocks within a bioferinery.
