  Antioxidant and β-glucuronidase inhibitory activities of the internal organ extract from sea cucumber stichopus japonicus

  Antioxidants and β-glucuronidase inhibitors have been used for treatment and prevention of various human diseases. The study aimed to investigate the antioxidant and β-glucuronidase inhibitory activities of the aqueous methanolic extract (80% MeOH) and its solvent fractions (n-hexane, CHCl3, EtOAc, BuOH, and water) prepared from the internal organs of sea cucumber Stichopus japonicus. The antioxidant and β-glucuronidase inhibitory properties varied between the solvent extract and fractions. The

  Screening bacterial strains for production of maltooligosyl trehalose trehalohydrolase and maltooligosyl trehalose synthase

  This research focused on screening strains bacteria were able to produce of trehalose from starch which is novel and economic method for trehalose production. We selected two strains that had MTSase and MTSase strong activity from ten strains that were isolated in Vietnam.

  Study on identification and biosynthesis of laccase by white rot fungi CP29

  White-rot fungi are the most efficiency degrader of wood lignin by having extracellular ligninolyitc enzymes system; lignin peroxidases, manganese peroxidases and laccase. Laccase has an important place in ligninolysis and has been widely applicated in some industries.
