White-rot fungi can degrade a wide spectrum of environmental pollutants, including pharmaceuticals, which are not efficiently removed from wastewater by conventional methods, e.g., the activated sludge method. However, treatment with use fungal cultures (mycoremediation) also has significant limitations: among others, need to appropriate, often-expensive culture media. We aimed screen 18 media ...

OBJECTIVES This study highlights xylanase overproduction from Bacillus mojavensis via UV mutagenesis and optimization of the production process. MATERIALS AND METHODS Bacillus mojavenis PTCC 1723 underwent UV radiation. Mutants' primary screening was based on the enhanced Hollow Zone Diameter/ Colony Diameter Ration (H/C ratios) of the colonies in comparison with the wild strain on Xylan agar...

Aim: Present study was conducted to examine the modulatory effect of different essential oils on rumen fermentation pattern in vitro using wheat straw based diet (concentrate: wheat straw 50:50). Materials and Methods: Four essential oils i.e. cinnamon, garlic, oregano and rosemary oils were tested at concentration of 0, 30, 300 and 600 mg/litre (ppm) of total culture fluid using in vitro gas p...

Propionibacterium arabinosum is known to produce an adeninylcobamide when grown in a medium containing yeast extract or corn steep-liquor (I, 2). Such a medium, although not intentionally fortified with a heterocyclic base, undoubtedly contains substantial amounts of adenine or its derivatives. Addition of an appropriate benzimidazole, purine, or other heterocyclic base to the medium, or to a s...

The work reported here presents the results of an investigation into the replacement of lactose by glucose or by sucrose in a corn steep liquor medium for the production of penicillin. Previous work has established (Johnson, 1946) that glucose and sucrose are metabolized by Penicillium chrysogenum at a more rapid rate than is lactose. Also, it has been shown that a maximum rate of penicillin pr...
