Bacteria have been isolated from 10 different strains of Phanerochaete chrysosporium, a white rot fungus which degrades lignocellulosic materials. The investigations showed that one or more bacterial species were always associated with the fungus. Various attempts to eliminate the bacteria on the fungus were unsuccessful. Three different bacterial species were isolated and identified. One of th...

using titanium dioxide nano-silver packaging, which is antibacterial and resistance to the diffusion of gases such as oxygen, is increasing in food industry. therefore, we compared the effect of titanium dioxide-based nano-silver packaging and conventional polyethylene packaging on the fungal flora of consuming bread in order to increase the shelf-life storage of consuming bread. one hundred fo...

  Background and Aims:Nosocomial infections cause considerable morbidity and mortality and pose high financial burden on healthcare systems. Although surface contact, surgical incisions, wounds and catheters are responsible for a high percentage of nosocomial infections, bacterial and fungal air contaminations in hospitals have an important role in development of hospital infections. The p...

In the framework of study on wood inhabiting Hyphomycetes in Gilan province, Iran, during 2002- 2003 eighteen taxa belonging to different genera were identified as follows: Chloridium botryoideum, Dendryphiopsis atra, Epicoccum nigrum, Periconia minutissima, Periconia byssoides, Periconia sp., Phaeoisaria clematidis, Pseudospiropes simplex, Sporidesmium adscendens, Sporidesmium brachypus, Spori...

The presence of guaiacol in cork stoppers is responsible for some cases of cork taint causing unpleasant alterations to wine. We have performed a characterization of the cork-associated microbiota by isolating 55 different microorganisms: eight yeast, 14 filamentous fungi or molds, 13 actinomycetes and 20 non-filamentous bacteria. A screening for degradation of vanillic acid and guaiacol produc...

Catalase/peroxidases (KatGs) are bifunctional haem b-containing (Class I) peroxidases with overwhelming catalase activity and substantial peroxidase activity with various one-electron donors. These unique oxidoreductases evolved in ancestral bacteria revealing a complex gene-duplicated structure. Besides being found in numerous bacteria of all phyla, katG genes were also detected in genomes of ...

Out of the 104 actinomyceles tested 56% of the isolates exhibited antagonistic effect towards gram-negative bacleria and 35.6% toward<; grnm-positive bacteria. 1be concentrations required to bring about 100% inhibitio...

Humans are colonized by diverse populations of bacteria and fungi when in a healthy state and in the settings of disease, and the interactions between these microbial populations can be beneficial or detrimental to the host [1]. Among these microbial populations, Candida albicans is the fungus most commonly detected in association with humans [2], and numerous studies have described C. albicans...

Entomopathogenic fungi are potential tools to biocontrol cicadellids and delphacids, two groups of insects that cause extensive damage to agricultural crops. However, bacteria living on the host cuticle may inhibit fungal growth. In the present work, following the molecular characterization of 10 strains of Bacillus isolated from the integument of cicadellids and delphacids, we selected isolate...
