cadmium effects on soil microbial indices and on the interaction of arbuscular mycorrhiza fungi (amf) and as well on plant growth promoting rhizobacteria (pgpr) were investigated. the experiments were performed in the framework of a factorial design with levels of cadmium (0, 10, 30 and 100 mg kg-1 soil), and microbial inoculations (control, pgpr and amf) employing russian kanapweed as the expe...

Beginning in the 1980s, concerns about the deleterious effects of synthetic pesticides have driven a significant Southeast Asian research and development effort directed towards alternative pest control strategies, including the use of microbial control agents. Despite this effort, use of microbial control agents has grown slowly in the region. This is the result of an interplay between interna...

The application of herbicides as organic chemical compounds to control pest and weeds may affect the population and activity of microorganisms, and this may have an influence on biochemical processes that are important for soil fertility and plant growth. The primary objective of this study was to evaluate different loading rates of eradican (EPTC) on soil microbial biomass C and N, microbial b...

The potential benefits of cooperation in microorganisms can be undermined by genetic conflict within social groups, which can take the form of 'cheating'. For cooperation to succeed as an evolutionary strategy, the negative effects of such conflict must somehow be either prevented or mitigated. To generate an interpretive framework for future research in microbial behavioural ecology, here we o...

Background: Edible films and coatings have potential benefits for food packaging, particularly meat products. These coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. In this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of  5 days was...

This article gives a very brief overview of the antibiotic era, beginning from the discovery of first antibiotics until the present day situation, which is marred by the emergence of hard-to-treat multiple antibiotic-resistant infections. The ways of responding to the antibiotic resistance challenges such as the development of novel strategies in the search for new antimicrobials, designing mor...

Background and Aim: The human bowel contains a large and dynamic bacterial population (more than 500 species of bacteria). Some intestinal bacteria such as Streptococcus bovis , Enterococcus and Bacteroides fragilis have previously been suggested to be implicated in the promotion of colon carcinogenesis probably through the conversion of mutagen metabolites. Materials and Methods: Thirty patie...

The addition of organic and inorganic substrates to calcareous soils low in organic matter and nitrogen contents may change soil microbial biomass and activity. In order to investigate the effect of chemical and organic fertilizers on soil CO2 production and microbial biomass C, a field experiment was conducted under maize cultivation. The experimental design was split-plot arranged in randomiz...
