This study investigates the potential of epiphytic bacteria isolated from citrus fruits to control green mold post-harvest disease caused by Penicillium digitatum in Thompson Navel sweet oranges north Iran. Twenty-three were and screened vitro against P. digitatum, 13 isolates with antagonistic activity selected for further studies. Isolates B15 (Bacillus sp.), P17 (Pseudomonas S13 (Streptomyce...

Nocardiae are Gram-positive, filamentous, aerobic, relatively slow-growing, and weakly acid-fast bacteria which cause nocardiosis in humans. We describe a 53-year-old patient with chronic bronchitis referred to Al-Zahra Hospital, Isfahan. A bronchial washing sample was taken from the patient. A Nocardia-like microorganism was detected in microscopic evaluation. Based on the phenotypic and 16S r...

There are only two reports in the literature demonstrating the presence of Campylobacter spp. in marine mammals. One report describes the isolation of a new species, Campylobacter insulaenigrae sp. nov., from three harbor seals (Phoca vitulina) and a harbor porpoise (Phocoena phocoena) in Scotland, and the other describes the isolation of Campylobacter jejuni, Campylobacter lari, and an unknown...

Detection of Mycoplasma synoviae (MS) by culture and polymerase chain reaction (PCR) has been reported from commercial chicken farms in different provinces of Iran. In some reports the phylogenetic analysis of MS isolates based on 16S rRNA and variable lipoprotein hemagglutinin (vlhA) genes have been carried out. The PCR product containing partial 16S rRNA genes of Iranain isolates was sequence...

OBJECTIVES The study aimed to investigate the prevalence and epidemiological characteristics of blaNDM-1 (encoding New Delhi metallo-β-lactamase 1) in Enterobacteriaceae and the Acinetobacter calcoaceticus-Acinetobacter baumannii complex (ABC) in China from July 2011 to June 2012. METHODS PCR was used to screen for the presence of blaNDM-1 in all organisms studied. For blaNDM-1-positive strai...

This study aimed to isolate and identify acidophilic actinobacteria. Acidophilic actinobacteria isolates were had from a paddy field soil in Osmancık placed near Çorum province Turkey. The dilution plate technique on seven selective media with pH 5.5 was used for isolation. 16S rRNA gene PCR amplification of performed. Three different algorithms the phylogenetic analyzes made MEGA 7.0 software....

The purpose of this study was to isolate and characterize Proline Dehydrogenase (ProDH) enzyme frommicroorganisms isolated from soil in Iran. Isolation and screening of L-proline degradative enzymes from soilsamples was carried out. The isolate was characterized by biochemical markers and 16S rRNA geneanalysis. The target ProDH was purified and the effects of pH and temperatur...

Almonds (Prunus amygdalus) represent an important crop in most Mediterranean countries. A new and devastating disease of almond trees in Lebanon was recently reported, characterized by the development of severe witches'-brooms on which no flowers or fruits developed, and leading to tree death within a few years. A phytoplasma was detected in diseased trees by PCR amplification of rRNA operon se...

Ammonia oxidation, as the first step in the nitrification process, plays a central role in the global cycling of nitrogen. Although bacteria are traditionally considered to be responsible for ammonia oxidation, a role for archaea has been suggested by data from metagenomic studies and by the isolation of a marine, autotrophic, ammonia-oxidizing, non-thermophilic crenarchaeon. Evidence for ammon...

Biocathode microbial communities are proposed to catalyse a range of useful reactions. Unlike bioanodes, model biocathode organisms have not yet been successfully cultivated in isolation highlighting the need for culture-independent approaches to characterization. Biocathode MCL (Marinobacter, Chromatiaceae, Labrenzia) is a microbial community proposed to couple CO2 fixation to extracellular el...
