This study presents the distribution of bacterial and fungal abundances in long-term copper (Cu) contaminated soils Topolnitsa-Pirdop valley – a highly industrialized zone with number mines processing plants for other non-ferrous metals. The (16S rRNA gene copies) (ITS were estimated using quantitative PCR technique five topsoils, differently Cu (ranging from 28.05 to 198.9 mg kg -1 ). Bacteria...

1- (Phthalazin-l'-yl-amino)-3-chloro-4-aryl-4H-(4o-rm ethyl)-2-azetidinones (3) were prepared by cycloaddition of-methyl substituted benzal hydrazinophthalazine (2) with chloro acetylchloride. The hydrazone (2) was synthesised by the condensation of 1- hydrazinophthalazine (1) with substituted aromatic aldehydes, ketones 7 acetophenones. 1- Hydrazinophthalazine was prepared from the phthal...

there is a long period between harvested beets and their transfer to the sugar factory. sugar beet crop is damaged and injured during harvest and transport which provides a suitable place for various saccharoliytic microorganisms growth in terms of temperature, moisture, ph and glucose concentration. in this study, samples were randomly selected from the roots stored in spring 2010 and also the...

Genetic analysis of indoor air has uncovered a rich microbial presence, but rarely have both the bacterial and fungal components been examined in the same samples. Here we present a study that examined the bacterial component of passively settled microbes from both indoor and outdoor air over a discrete time period and for which the fungal component has already been reported. Dust was allowed t...

Background & Aim:During recent decades, infections disease resulting from opportunistic fungi such as Candida albicans and resistance increasing of human pathogenic bacteria to current antibiotics has led to many problems for treating of these diseases. The aims of the present study was to investigate anti-fungi and anti-bacterial effects of Eucalyptus extract...

• Bacterial richness declined but fungal increased under salinization. Bacteria did not become interactively compact or facilitative Fungi exhibited more compartmentalized and competitive patterns Fungal stability showed steeper increases salinization than bacterial stability. Soil is a typical environmental challenge in arid regions worldwide. Salinity stress plant convergent adaptations inter...

Fungi are absorptive feeders and thus must colonize and ramify through their substrate to survive. In so doing they are in competition, particularly in the soil, with myriad microbes. These microbes use xenobiotic compounds as offensive weapons to compete for nutrition, and fungi must be sufficiently resistant to these xenobiotics. One prominent mechanism of xenobiotic resistance is through pro...

Antibiotic use in humans has been associated with outgrowth of fungi. Here we used a murine model to investigate the gut microbiome over 76 days of treatment with vancomycin, ampicillin, neomycin, and metronidazole and subsequent recovery. Mouse stool was studied as a surrogate for the microbiota of the lower gastrointestinal tract. The abundance of fungi and bacteria was measured using quantit...

Meadows are natural dynamic features of forested mountain landscapes of the Pacific Northwest. Proportions of meadows and forests change with environmental conditions and disturbance history. We investigated the belowground microbial communities associated with these two vegetation types and how they change across the meadow–forest transition at two sites in Oregon. Soils were sampled along rep...
