Expression of sfp gene and hydrocarbon degradation by Bacillus subtilis
Bacillus subtilis C9 produces a lipopeptide-type biosurfactant, surfactin, and rapidly degrades alkanes up to a chain length of C19. The nucleotide sequence of the sfp gene cloned from B. subtilis C9 was determi...

Extracellular production of a glycolipid biosurfactant, mannosylerythritol lipid, from Candida antarctica
Candida antarctica (sp. SY16) required avegetable oil as the carbon source to produce a biosurfactant, mannosylerythritol lipid (MEL-SY16). Biosurfactant production was 31 g l−1 after 7 days in a batch culture a...

Sulfated Glucuronorhamnoxylan from Capsosiphon fulvescens Ameliorates Osteoporotic Bone Resorption via Inhibition of Osteoclastic Cell Differentiation and Function In Vitro and In Vivo
Excessive osteoclast differentiation and/or bone resorptive function causes a gradual loss of bone, leading to the pathogenesis of bone diseases such as osteoporosis (OP). In this study, a sulfated glucuronorh...
