The fluorescence method of detecting aflatoxin-producing strains of Aspergillus flavus and related species utilizes the ultraviolet-induced fluorescence of aflatoxin produced in a modified Czapek's solution agar containing corn steep liquor, HgCl(2), and (NH(4))H(2)PO(4) instead of NaNO(3). The presence of aflatoxin is confirmed by thin-layer chromatography of CHCl(3) extracts of the fluorescin...

the purpose of this research was to design a semi-industrial culture medium to obtain the maximum biomass production from bacterium bacillus subtilis utb96. in the first step, in order to reduce the cost of culture medium components, commercial products and industrial by products including, sugar beet molasses, sugar cane molasses, potato waste water and milk serum as carbon sources and corn st...

The effect of UMMB supplementation on rumen micro ora was investigated in  fteen healthy rumen  stulated buffalo calves divided into three groups having  ve animals in each. The animals of group I, II and III were kept on conventional diet, wheat straw alone and wheat straw supplemented with UMMB, respectively. Rumen liquor samples were collected at different time intervals for three consec...

in order to reduce the costs associated with poly-β-hydroxybutyrate production, growth and poly-β-hydroxybutyrate production of ralstonia eutropha were studied in batch culture on different carbon sources. experiments were designed and conducted to not only lower the cost of poly-β-hydroxybutyrate production by using inexpensive substrates, but also to increase poly-β-hydroxybutyrate production...

BACKGROUND Paper pulp wastewater resulting from alkaline extraction of wheat straw, known as black liquor, is very difficult to be treated and causes serious environmental problems due to its high pH value and chemical oxygen demand (COD) pollution load. Lignin, semicellulose and cellulose are the main contributors to the high COD values in black liquor. Very few microorganisms can survive in s...

Condensed fermented corn extractives (liquid steep liquor) was assessed as an alternative to organic acids in broiler chicken. Day-old Ross 308 chicken (n = 180) were allocated into six treatments (basal diet with no supplement, basal supplemented 1 and 2 cc/kg liquid liquor (CSL) or formic acid along probiotic (1 × 108 CFU/g, Lactobacillus acidophilus, casei) a completely randomised design fiv...

Erosion took a serious toll of prime topsoil from wheat fields in the Pacific Northwest United States since farming began in the 1870s. By the mid-1900s, it had become a serious environmental and economic threat to the region that produces world-record rainfed grain yields and almost 13% of the US wheat crop. Of significance is that 80% of the nation’s specialty soft white wheat is grown here f...
