Clonostachys rosea f. catenulata (syn. Gliocladium catenulatum) is an effective fungal biological agent against Fusarium root and stem rot and Pythium damping-off diseases on cucumber plants. Both chitinase and [beta]-1,3-glucanase enzymes were produced when C. rosea was grown on a synthetic medium containing chitin or laminarin as a sole carbon ...

Fluorescent in situ hybridization (FISH) using taxon-specific, rRNA-targeted oligonucleotide probes is one of the most powerful tools for the rapid identification of harmful microorganisms. However, eukaryotic algal cells do not always allow FISH probes to permeate over their cell walls. Members of the pathogenic micro-algal genus Prototheca are characterized by ...

The antimicrobial activities of the class Ha bacteriocin divergicin M35 and several types of chitosan against Listeria monocytogenes were quantified by agar diffusion, critical micro-dilution, and viable count and observed by electron microscopy. Antimicrobial activity of chitosan depended on its molecular mass (MM) and the pH. Three chitosans with MM ...

Phthalates are ubiquitous environmental pollutants associated with endocrine disruption and peroxisome proliferation in experimental animals. In yeasts exposed to environmental chemicals, including phthalates, alterations in cell growth, cellular morphology, and H202 detoxification occur. Nutrient availability also influences diverse cellular processes.

Composting is a microbial process that converts organic waste into a nutrient-rich end product used in horticultural and agricultural applications. The diversity and long-term succession of microorganisms found in composted biosolids has been less characterized than other composts. In this study, bacterial and fungal communities found in composted biosolids aging ...

Pasteurized and unfermented milks supplemented with probiotic bacteria are appearing on the market. It then becomes a challenge to ascertain the undesirable contamination microbiota in the presence of a largely superior population of probiotic bacteria. A method to enumerate the contaminating microbial microbiota in such probiotic-enriched milks was developed. The ...

In the yeast Saccharomyces cerevisiae, the paralogous genes ALT1 and ALT2 have been proposed to encode alanine aminotransferase isozymes. Although in other microorganisms this enzyme constitutes the main pathway for alanine biosynthesis, its role in S. cerevisiae had remained unclear. Results presented in this paper show that under respiratory conditions, ...

Helicobacter pylori is a common gastrointestinal pathogenic bacterium in humans and the usual preference for the stomach's outer membrane proteins (OMPs) are antigens involved in the adhesion process. Through SDS-PAGE and blotting analyses, using horseradish peroxydase-labeled heparan sulfate (HRP-HS) as a probe, we identified H. pylori OMPs with affinity for ...

An easy gene-knockout technique, PCR-based one-step inactivation of chromosomal genes, is widely used in Escherichia coli and related enterobacteria to construct mutants. In this study, we adapted this technique to construct genomic island and large operon deletion mutants of Erwinia amylovora, including the 33.4 kb hrp-type III secretion (T3SS) pathogenicity ...

[beta]-D-Fructofuranosidase (FFase), an important enzyme of the confectionery and fructose syrup industry, is produced by several microorganisms. However, yeasts are the most used source because of their high sucrose fermentation capacity. In this work, production of FFase was carried out in submerged fermentation using a high enzyme-producing yeast strain. Plackett-Burman ...

The species diversity and distribution of 3 ecological groups of fungi (viz., foliar endophytes, phellophytes, and leaf litter fungi of 6 tree hosts of a dry thorn forest and 6 tree hosts of an evergreen forest of southern India) were studied. As the methods of sampling and the isolation procedure ...

Plant growth-promoting rhizobacteria (PGPR) can have positive effects on vigour and productivity, especially under stress conditions. In asparagus (Asparagus officinalis L.) field culture, seeds are planted in high-density nurseries, and 1-year-old crowns are transplanted to production fields. Performance can be negatively affected by water stress, transplant shock, and disease pressure ...

A novel feather-degrading bacterium was isolated from a polluted river and identified as Bacillus licheniformis RPk. The isolate exhibited high proteinase production when grown in chicken-feather media. Complete feather degradation was achieved during cultivation. Maximum protease activity (4150 U/mL with casein as a substrate and 37.35 U/mL with keratin as ...
