Native wild yeasts from forest ecosystems represent an interesting potential source of biocontrol organisms in synergy with disease-tolerant materials. Yeasts have a combination competitive mechanisms and low requirements for their biotechnological application as agents. The current study aimed to increase the number candidates against Fusarium circinatum Diplodia sapinea. enzymatic antagonisti...

In the present study, an attempt was made to biochemically characterize the antimicrobial substance from the soil isolate designated as RLID 12.1 and explore its potential applications in biocontrol of drug-resistant pathogens. The antimicrobial potential of the wild-type isolate belonging to the genus Bacillus was determined by the cut-well agar assay. The production of antimicrobial compound ...

biotic as well as abiotic factors may influence the biocontrol activity and population density of pseudomonas fluorescens. however, limited studies have been carried out on the effects of extracellular metabolites of other competitor bacteria, especially on the biocontrol efficiency of p. fluorescens. a greenhouse experiment was conducted to evaluate the potential of the two p. fluorescens isol...

The present study was designed to evaluate the therapetuical role of chromium-enriched yeast saccharomyces cerevisiae (Sc Cr) on genetic alterations and sperm changes in STZ-induced hyperglycemic rats. Six groups of male rats were used and included a group of non-diabetic control animals, the second group was of diabetic animals, third, fourth, fifth and sixth groups consisted of diabetic anima...

The killer phenomenon is defined as the ability of some yeast to secrete toxins that are lethal to other sensitive yeasts and filamentous fungi. Since the discovery of strains of Saccharomyces cerevisiae capable of secreting killer toxins, much information has been gained regarding killer toxins and this fact has substantially contributed knowledge on fundamental aspects of cell biology and yea...

background: the immunity and health of newborn calf are related to immunoglobulins uptake from colostrum where treatment of colostrum may improve the uptake. objectives: the purpose of this study was to investigate the effect of controlled heat-treating of colostrum and antibiotic addition on immunoglobulins absorption, performance and health parameters of calf. methods: the colostrum pool was ...
