چکیده- تصفیه آلاینده ها به صورت هوازی توسط میکروارگانیسم ها فرایندی است سازگار با محیط زیست که در آن آلاینده ها توسط فرایند بیولوژیک پاکسازی می گردند. aroclor1254 از مشتقات متنوع (pcbs) تشکیل شده است که این ترکیبات خود یک آلاینده پایدار به شمار می آید. میزان مصرف یا رهاسازی دقیقی از این ماده در محیط زیست ایران وجود ندارد. یک کارخانه تولید ترانسفورماتور در جنوب شرق شیراز از روغن ترانسفورماتور ...
A Gram-positive, non-motile, pale-yellow, short rod-shaped bacterium, strain DCY26(T), was isolated from soil of a ginseng field in South Korea and was investigated to determine its taxonomic position. The organism grew optimally at 30-37 degrees C. The G+C content of its DNA was 65.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain DCY26(T) was related most clo...
Microbial communities in the endosphere of Salicaceae plants, poplar (Populus trichocarpa) and willow (Salix sitchensis), have been demonstrated to be important for plant growth promotion, protection from biotic and abiotic stresses, and degradation of toxic compounds. Our study aimed to investigate bio-control activities of Salicaceae endophytes against various soil borne plant pathogens inclu...
Eighty-seven culturable endophytic bacterial isolates in 19 genera were obtained from coffee plants collected in Colombia (n = 67), Hawaii (n = 17), and Mexico (n = 3). Both Gram positive and Gram negative bacteria were isolated, with a greater percentage (68%) being Gram negative. Tissues yielding bacterial endophytes included adult plant leaves, various parts of the berry (e.g., crown, pulp, ...
Here we present the draft genome of an actinobacterium, Curtobacterium flaccumfaciens strain UCD-AKU, isolated from a residential carpet. The genome assembly contains 3,692,614 bp in 130 contigs. This is the first member of the Curtobacterium genus to be sequenced.
Assigning ecological roles to bacterial taxa remains imperative to understanding how microbial communities will respond to changing environmental conditions. Here we analyze the genus Curtobacterium, as it was found to be the most abundant taxon in a leaf litter community in southern California. Traditional characterization of this taxon predominantly associates it as the causal pathogen in the...
Much genetic diversity within a bacterial community is likely obscured by microdiversity within operational taxonomic units (OTUs) defined by 16S rRNA gene sequences. However, it is unclear how variation within this microdiversity influences ecologically relevant traits. Here, we employ a multifaceted approach to investigate microdiversity within the dominant leaf litter bacterium, Curtobacteri...
Endophytic bacteria were isolated from stems of Eucalyptus spp (Eucalyptus citriodora, E. grandis, E. urophylla, E. camaldulensis, E. torelliana, E. pellita, and a hybrid of E. grandis and E. urophylla) cultivated at two sites; they were characterized by RAPD and amplified rDNA restriction analysis (ARDRA). Endophytic bacteria were more frequently isolated from E. grandis and E. pellita. The 76...
Background and Aim: Cystic fibrosis is a common hereditary and autosomal disorder. One of the factors in cystic fibrosis is Burkholderia cepacia which can be transmitted through the sharing of admitted patients with hospitalized patients. Purpose of this study, was isolation and identification of Burkholderia cepacia from respiratory secretions from Masih Daneshvari Hospital cystic fibrosis...
ABSTRACT Plant growth-promoting rhizobacteria (PGPR) strains INR7 (Bacillus pumilus), GB03 (Bacillus subtilis), and ME1 (Curtobacterium flaccumfaciens) were tested singly and in combinations for biological control against multiple cucumber pathogens. Investigations under greenhouse conditions were conducted with three cucumber pathogens-Colletotrichum orbiculare (causing anthracnose), Pseudomon...
