Growth rate, lag phase and OTA production of a mixed inoculum of four Aspergillus carbonarius strains were compared to the behaviour of the single strains at 30 °C on Czapek Yeast Extract Agar. Significant differences ...

Methane production from swine wastewater was evaluated by using three inoculums: rumen (I1), stabilized swine wastewater (I2) and sewage sludge (I3). Experimental design was based on four treatments by duplicate: T0: swine ...

Biosurfactants are one of the mainly class of natural surfactants and are classified according to their chemical composition and microbial origin. The production of biosurfactants by microorganisms is intimately linked to ...

Some compounds of microbial origin exhibit surfactant properties and are known as biosurfactants, which are byproducts of bacteria, fungi and yeasts metabolism. The present study aims to evaluate the effect of the pre-inoculum ...

One of the possible ways of recovering the environmental quality of contaminated soils is the bioremediation process, in which soil pollutants are degraded using microorganisms. In this context, the evaluation of the ...

The increasing demand for animal protein has driven significant changes in cattle breeding systems, mainly in feedlots, with the use of young bulls fed on diets richer in concentrate (C) than in forage (F). These changes ...
