Attenuation of N-nitrosodiethylamine-induced liver carcinogenesis in rats by naturally occurring diallyl sulfide

  The present study was aimed to investigate the chemopreventive effects of diallyl sulfide (DAS),  organosulfur compounds present in high amounts in garlic, against N-nitrosodiethylamine (NDEA) induced  hepatocarcinogenesis in rats. NDEA treatment to rats resulted in significantly elevated levels of serum  aspartate transaminase, alkaline phosphatase, lactate dehydrogenase and...

Some properties of extracellular protease from Bacillus licheniformis LBBL-11 isolated from “iru”, a traditionally fermented African locust bean condiment

  Twelve strains of Bacillus licheniformis isolated from traditionally fermented African locust bean (iru) were evaluated in respect to production of protease on skim milk agar. B. licheniformis LBBL-11 exhibited the highest proteolytic activity with a diameter of clear zone measuring 35.0 mm. Production of protease from B. licheniformis LBBL-11 was further studied by growing...
