A method for the production of a rhamnolipid. The method includes culturing in a fermentation medium an organism capable of producing a rhamnolipid to form a fermentation broth comprising at least one rhamnolipid and having a pH>5; extracting at least one lipophilic impurity from said fermentation broth; acidulating said fermentation broth to form an aqueous medium of pH<5 comprising the at least one rhamnolipid; extracting the at least one rhamnolipid from said acidulated fermentation broth; and separating the at least one rhamnolipid to obtain a purified rhamnolipid.

The invention relates to cells which make rhamnolipids and are genetically modified such that they have a decreased activity, compared to the wild type thereof, of an ABC glucose transporter and, compared to the wild type thereof, an increased activity of at least one non-ABC glucose transporter and to a method for producing rhamnolipids using the cells according to the invention.

Disclosed are a composition for production of ginsenoside compound K using a high temperature-?-glycosidase and a high temperature-?-L-arabinofuranosidase, and a method for preparing ginsenoside compound k. The composition for producing ginsenoside compound k and the method for preparing ginsenoside compound k according to one aspect of the present invention allow high temperature-?glycosidase and high temperature-a-L-arabinofuranosidase to exhibit stable activity even at high temperatures, thereby increasing a reaction rate. The composition for producing ginsenoside compound k and the method for preparing ginsenoside compound k according to one aspect of the present invention allow a large quantity of ginsenoside compound k to be produced in a short time, thereby exhibiting an effect of producing a high yield, and thus can be utilized industrially.

The present disclosure generally relates to biological platforms for the conversion of cellulosic biomass into fuels and chemicals. More specifically, the present disclosure relates to the conversion of cellulosic materials into sugar acids or their salts, which may then be used to produce commodity chemicals. In one aspect, the present disclosure relates to a recombinant host cell including: reduced activity of one or more polypeptides having P-glucosidase activity as compared to a corresponding wild type cell, where each of said one or more polypeptides are encoded by a gene that has at least 80% sequence identity to a gene.
