Studies were carried out on the fermentative production of g-linolenic acid (GLA) using seven strains belonging to Mucorales. An oleaginous fungal strain, isolated from the Western Ghats of Kerala produced GLA at a level of 8 % (by mass), when grown in a complex medium containing glucose as the sole carbon source. Effects of different culture conditions were investigated in shake flasks. Maximu...

Bacterial cellulose (BC) synthesized by Gluconacetobacter sucrofermentans has a high degree of crystallinity, durability, great resistance, and biocompatibility. This study evaluates the effect that carbon and nitrogen sources, present in HS (Hestrin–Schramm) culture medium, have on BC from G. sucrofermentans CECT 7291 used to restore damaged documents. The initial pH of the medium and the temp...

Nu-Lure and other protein solutions were presented to Anastrepha suspensa in J-tubes and consumption was quantified spectrophotometrically. In choice comparisons, flies consumed more or equal water compared to Nu-Lure and more Nu-Lure compared to Bragg’s Liquid Aminos, corn steep liquor, NZ case, pepticase, Solulys, soy hydrolysate, Torula yeast, whey, and yeast enzymatic hydrolysate. Consumpti...

addition, radiolabeling studies done by Carter et al. have shown that the L-/?-lysine side chain of viomycin is derived from L-lysine7). Therefore, we reasoned that if the y-hydroxy-/?-lysine side chain of tuberactinomycin A was derived from L-/Mysine, then the addition of AEC would inhibit its formation and tuberactinamine A would accumulate as the final product. This hypothesis was demonstrat...

In the future, due to limited resources, a crisis of energy storing molecules (fuels), which are currently produced from crude mineral oil, is expected. One strategy to compensate a part of the oil defi ciency is the production of biodiesel from microalgal lipids. As model microorganism for lipid production microalgae Euglena gracilis was selected and photo-mixotrophic cultivation was performed...

In this work, biosurfactant production by a Pseudomonas aeruginosa strain was optimized using low-cost substrates. The highest biosurfactant production (3.2 g/l) was obtained using a culture medium containing corn steep liquor (10% (v/v)) and molasses (10% (w/v)). The biosurfactant reduced the surface tension of water up to 30 mN/m, and exhibited a high emulsifying activity (E24=60%), with a cr...

Five experiments were conducted with 282 f'mishing pigs to evaluate the use of condensed fermented corn solubles with germ meal and bran as an amino acid source for swine. This wet milling byproduct referred to as dried steep liquor concentrate (DSLC) is becoming a major byproduct of the industry as methods of corn processing change. DSLC serving as the only amino acid supplement for corn suppo...

The disposal and the treatment of sewage sludge is an expensive and environmentally complex problem. In this work, a lipopeptide biosurfactant extracted from corn steep liquor was used as ecofriendly and cost-competitive alternative for the mobilization and bioremediation of fluorene in sewage sludge. Results have demonstrated that this biosurfactant has the capability to mobilize fluorene to t...

In this study, we have shown the microbial alkaline protease production by using isolated Bacillus subtilis. Bacillus subtilis which produces an extracellular alkaline protease was isolated from meet surface purchased from local Egyptian markets. Maximum enzyme activity was achieved when the bacterium was grown on corn steep liquor (2.0 %, w/v) instead of soybean meal (2 %) followed by casein h...
