It is important to identify and recover bacteria associating with fungi under natural soil conditions to enable eco-physiological studies, and to facilitate the use of bacterial-fungal consortia in environmental biotechnology. We have developed a novel type of baiting microcosm, where fungal hyphae interact with bacteria under close-to-natural soil conditions; an advantage compared to model sys...

3,3′-Diaminobenzidine was applied at doses of 5, 10, 25, and 50 mg kg−1 of soil and their effects were evaluated on indigenous soil microbial communities (viable aerobic bacteria, fungal populations, aerobic N2-fixing bacteria, denitrifying, and nitrifying bacteria), and soil enzymatic activities (acid and alkaline phosphatases, arylsulfatase, and dehydrogenase). At doses of 5 or 10 mg kg−1, 3,...

Polyacrylamide (PAM) is used in agriculture to reduce soil erosion and has been reported to reduce turbidity, nutrients, and pollutants in surface runoff water. The objective of this work was to determine the effect of PAM on the concentration of enteric bacteria in surface runoff by comparing four enteric bacteria representing phenotypically different motility and hydrophobicity from three soi...

Since 1999, introduced Trachemys scripta elegans from artificial and natural water bodies in the Po plain (North Italy) were bacteriologically screened. From 2001 onwards, a survey of Emys orbicularis was started in the same area. 15 carcasses and 349 cloacal swabs from T. s. elegans, and 100 cloacal swabs from E. orbicularis have been studied. Most samples yielded positive bacteriological resu...

The Bacillus genus is a heterogeneous group of Gram-positive, facultative anaerobic, endospore-forming bacteria spread into the environment, even though soil is generally accepted as its natural reservoir. The ability to produce endospores allows Bacillus to withstand extreme environmental conditions as those occurring in food processing. Bacillus spp., particularly B. subtilis, are usually fou...

background & aim:vaginal disease has always been a great concern of women. medicinal plants as natural resources with fewer side effects can effectively treat these infections given the diversity of these infections, resistance to antibiotics and side effects of existing drugs. the present study aimed to compare antimicrobial effects of methanol extract of francoeuria undulata on growth of seve...

Background and Purpose: The Phytoremediation efficiency of heavy metals is one of the important points in environmental studies. This research was conducted to investigate the effect of cow manure, elemental sulfur, and EDTA on Cd uptake by Indian mustard in a Cd-polluted soil in the presence of Thiobacillus thiooxidans. Materials and Methods: Treatments consisted of applying cow manure (0, 5,...
