Mexico is among the most important citrus fruit producers in world. However, during storage, several problems related to fungi can arise. The common fungal postharvest diseases detected on Citrus limon var Eureka (Italian lime) produced Tamaulipas state are green/blue mold (Penicillium spp.), fusarium rot (F. oxysporum, F. solani, proliferatum, others), and anthracnose (Colletotrichum spp.). In...

SO2 is traditionally used to limit or nullify the proliferation of spoilage yeasts in must/wine, but its use has become controversial due negative effects on human health. An alternative strategy for control biocontrol yeasts. Wickerhamomyces anomalus an outstanding biocontroller yeast that been examined by our group and a good agent against Brettanomyces bruxellensis Zygosaccharomyces rouxii. ...

the purpose of this research was to study the antimicrobial activities of the endophytic fungi from sesbania grandiflora (l.) pers. the endophytic fungi were isolated from branches and leaves of sesbania grandiflora (l.) pers., and sixty nine isolates were obtained. all isolates were screened for antibacterial and antifungal activities. the indicator organisms were 4 bacteria including staphylo...

The induction of tetraploidy by means of cold, heat and multiple heat shock treatments was investigated on male fish from a growth-enhanced transgenic tilapia C118 line, crossed with wild type females. After the development a new multiple heat shock protocol (two heat treatments at 41oC in 60 and 80 min. after fertilization for 5 min. per each), chromosome and X-gal in situ staining assays demo...

Aspergillus fumigatus is a saprophyte fungus, widely spread in a variety of ecologicalniches and the most prevalent aspergilli responsible for human and animal invasiveaspergillosis. The first step to develop novel and efficient therapies is the identificationand understanding of the key tolerance and virulence factors of pathogens. The mainfocus of the present study is to perform the similarit...

Xylose-assimilating yeasts with tolerance to both fermentation inhibitors (such as weak organic acids) and high temperature are required for cost-effective simultaneous saccharification and cofermentation (SSCF) of lignocellulosic materials. Here, we demonstrate the construction of a novel xylose-utilizing Saccharomyces cerevisiae strain with improved fermentation ability under heat and acid co...

Aim: Yeasts are present as natural microflora on surface of fruits and vegetables that have eminent importance from deputing biocontrol agents to reduce pathogens the health benefits humans.
 Materials Methods: were isolated using standard plate count technique. Colony morphology yeasts isolates characterized under microscope for their cell shapes sizes. Biochemical characteristics presenc...

The strains of the yeast Metschnikowia pulcherrima have strong biocontrol activity against various microorganisms. Biocontrol activity of M. pulcherrima largely depends on its iron immobilizing pigment pulcherrimin. Biocontrol activity of pulcherrimin producing strain, M. pulcherrima UMY15, isolated from local vineyards, was tested on different molds that cause food spoilage. M. pulcherrima UMY...
