The bioprospecting of secondary metabolites with antimicrobial action produced by filamentous fungi isolated from various ecosystems using agro-industrial residues is considerable importance, since it reconciles the discovery new agents reduction environmental impacts adding economic value to wastes. present paper investigated potential for production alternative media based on corn steep liquo...

The industrial washing of corn grain during its milling generates a residue known as “corn steep liquor (CSL)”. This is rich in amino acids, carbohydrates, vitamins, and mineral nutrients that can stimulate the vegetative growth when applied to plants. However, mode action this product not yet known. work involved foliar root application pepper plants, at dose 5 mL L−1, two CSL products (CSL-H ...

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...

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...

Laccase production by Coriolopsis caperata RCK2011 under solid state fermentation was optimized following Taguchi design of experiment. An orthogonal array layout of L18 (2(1) × 3(7)) was constructed using Qualitek-4 software with eight most influensive factors on laccase production. At individual level pH contributed higher influence, whereas, corn steep liquor (CSL) accounted for more than 50...

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...

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...
