where R.sub.1 is either COCH.sub.3 or H; and R.sub.2 is between two to ten O-linked 3,5-dihydroxydecanoate; and R.sub.3 can be a polyol (e.g., L- or D-glycerol, L- or D-threitol, L- or D-erythritol, L- or D-arabitol, L- or D-xylitol, L- or D-lyxitol, L- or D-ribitol, L- or D-allitol, L- or D-altritol, L- or D-mannitol, L- or D-iditol, L- or D-gulitol, L- or D-glucitol (also called sorbitol), L- or D-galactitol (also called dulcitol), and L- or D-talitol), 2-amino-D-mannitol, 2N-acetylamino-D-mannitol, L-rhamnitol, or D-fucitol; except when R.sub.3 is D-mannitol, R.sub.2 is not 2 nor 3 O-linked 3,5-dihydroxydecanoate chains. These liamocins described above in addition to D-mannitol liamocin A1, D-mannitol liamocin A2, D-mannitol liamocin B1, and D-mannitol liamocin B2, alone or in combination with each other, can be used to kill certain bacteria and to treat certain bacterial infections.

A process to produce a sophorolipid composition is disclosed, the steps including obtaining a sophorolipid containing composition having a pH of less than 5, adding 6 percent by weight or less of a free fatty acid to the composition, and thereafter adjusting the pH of the composition to a pH greater than 5. In some embodiments, the sophorolipid composition initially comprises from 4 to 80 percent by weight dry solids.

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.

An algae culture method capable of efficiently producing an osmotic pressure adjusting substance, a production method of the substance, and an algae culture method for recovering carbon dioxide from a mixed gas containing carbon dioxide and sulfurous acid gas. The methods involve preparing a plurality of enrichment cultures each containing betaine by culturing a culture of microalgae derived from an environmental specimen under a photoautotrophic condition and under a plurality of culture conditions; making a cultivation plan in which an optimum enrichment culture suitable for a main culture is selected from the plurality of enrichment cultures; producing a main culture that contains betaine under the photoautotrophic condition and a salt concentration of 10 wt. % or more; and separating betaine. In the main culture, the algae containing betaine are cultured while the mixed gas containing sulfurous acid gas and carbon dioxide is blown to a culture solution of the algae.
