Chitin degradation is one of the major steps in nutrients’ cycling, especially in marine environment. Chitinolytic bacteria play primary role in depolymerizing the complex polysaccharide in natural as well as sea food waste areas. Chitinolytic bacterium was isolated from a soil sample in medium containing edible crab shell waste as major carbon source. The strain showed clear zone of hydrolysis...

Purpureocillium lilacinum (Thom) Samsom is one of the most studied fungi in the control of plant parasitic nematodes. However, there is not specific information on its ability to inhibit some pathogenic bacteria, fungi, or yeast. This work reports the production of several antifungal hydrolytic enzymes by a strain of P. lilacinum when it is grown in a medium containing hair waste. The growth of...

The present study describes medium-chain-length polyhydroxyalkanoates (mcl-PHAs) production by the Pseudomonas Gl01 strain isolated from mixed microbial communities utilized for PHAs synthesis. A two-step fedbatch fermentation was conducted with glucose and waste rapeseed oil as the main carbon source for obtaining cell growth and mcl-PHAs accumulation, respectively. The results show that the P...

Cauliflower mushroom (Sparassis crispa) is well known as a brown-rot fungi selectively degrades heartwood of wood, and that has potential anticancer and immune enhancing activity; thus its production is increasing in Korea. The mushroom is cultivated artificially using plastic pots filled with medium material, such as lignocellulosic biomass and some additives. However, most of the medium remai...
