In this work, we report the overproduction of lipases by a new wild strain of Burkholderia lata (LBBIO-BL02) in submerged fermentation to seek an economically attractive bioprocess. The best fermentation medium composition was containing chicken fat (12.5 mL/L) and ammonium phosphate (15 g/L) at 35 ºC and pH 7.0, resulting in a lipase titer of 1137.82 U/mL(More)
The chemical composition and structural characterization of exopolysaccharides from the fungus Lasiodiplodia theobromae MMBJ are described, and the immunomodulatory activity of a purified β-glucan was evaluated. L. theobromae MMBJ produced three different β-glucans. One, fraction PEPS, was a branched (1→3)(1→6)-β-glucan and was insoluble in cold water. The(More)
