such petroleum hydrocarbons as ethylene oligomer are among soil and water pollutants. physical and chemical methods employed in elimination of these pollutants, in addition to being inefficient, are damaging to the environment too. throughout the present research, powerful decomposer isolates, namely: lysinibacillus xylanilyticus (a bacterium isolate), and aspergillus niger (a fungal isolate) w...

Agaricus blazei Murrill (ABM), an edible mushroom native to Brazil, is widely used for nonprescript and medicinal purposes. Alcohol liver disease (ALD) is considered as a leading cause for a liver injury in modern dietary life, which can be developed by a prolonged or large intake of alcohol. In this study, the medium composition of ABM was optimized using response surface methodology for maxim...

The entomopathogenic fungus, Nomuraea rileyi (Farlow) Samson was mass produced in different liquid media. The nine media of various nutrient sources were evaluated to find out most suitable medium for growth, biomass and viability of N.rileyi. Sabouraud’s dextrose broth with yeast extract proved to be superior which gave significantly highest cfu (8.33x10/ml) and biomass (6.10g). The next best ...

Potato protein liquor (PPL), a side stream from the potato starch industry, is normally used as fertilizer. However, with more than 100 g/L of sugars, 20 g/L of Kjeldahl nitrogen and Chemical Oxigen Demand (COD) of 300 g/L, it represents serious environmental challenges. The use of PPL for fungal cultivation is a promising solution to convert this waste into valuable products. In this study, PP...

The removal of polycyclic aromatic hydrocarbons from aqueous culture medium by the lignin-degrading marine fungus NIOCC # 312, obtained from decaying seagrass from a coral reef lagoon is reported here. We estimated the percentage of phenanthrene removed from the culture supernatant and the fungal biomass after 6 days. About 60-70% of phenanthrene, at a concentration of 12 mg l (12 ppm) was remo...

In this work, we propose the reuse of apple pomace as a substrate for fungal chitosan production by liquid cultivation of Gongronella butleri CCT4274. Different concentrations of reducing sugars and sodium nitrate were added to the aqueous extract of apple pomace and the best result was obtained with 40 g/L of reducing sugars and 2.5 g/L of sodium nitrate. The results indicate the possibility o...

Yarrowia lipolytica as an oleaginous yeast is capable of growing in various non-conventional hydrophobic substrate types, especially industrial wastes. In this study, the content thiamine (vitamin B1), riboflavin B2), pyridoxine B6), biotin B7) and folic acid B9) wet biomass Y. strains cultivated biofuel waste (SK medium), compared to standard laboratory YPD medium, was assessed. Additionally, ...
