There are still a large variety of microorganisms among aquatic animals which have not been explored for their pharmacological potential. Hence, present study was aimed to isolate and characterize a potent lactic acid bacterium from fresh water fish sample Zacco koreanus, and to confirm its pharmacological potential. Isolation of lactic acid bacteria (LAB)(More)
Extracellular cellobiase activity of Termitomyces clypeatus increased from 2.9 U ml−1 to 4.4 and 4.1 in presence of dithiothreitol (DTT) and β-mercaptoethanol (ME), respectively, with a decrease in Km from 0.4 to 0.3 mM (DTT) and 0.35 mM (ME). Catalysis was further enhanced if the reduced enzyme was alkylated and activity increased from 11.4 U ml−1(More)
In this study, the authors investigated the anti-melanogenic effects of 3,8-dihydroxyquinoline (jineol) isolated from Scolopendra subspinipes mutilans, the mechanisms responsible for its inhibition of melanogenesis in melan-a cells, and its antioxidant efficacy. Mushroom tyrosinase activities and melanin contents were determined in melan-a cells, and the(More)
The aim of the present study was to examine the antioxidative activity of (+)-lariciresinol (LRSL), an optically active lignan isolated from Rubia philippinensis in several in vitro assays. LRSL was also subjected to evaluate its inhibitory effect against the generation of reactive oxygen species (ROS) in murine macrophage (RAW 264.7) cells. The results(More)
