The present study is aimed at evaluating the effect of functional alginate coating incorporated with Lactoperoxidase (LPOS) and Zataria multiflora Essential Oil (ZEO) or both as natural additives on microbial and chemical characteristics of rainbow trout fillets. Firstly, Different treatments of trout fillets were prepared using ZEO (0.5 and 1%) and LPOS (5%) individually and in combination...
Microorganisms are vital in mediating the earth's biogeochemical cycles; yet, despite our rapidly increasing ability to explore complex environmental microbial communities, the relationship between microbial community structure and ecosystem processes remains poorly understood. Here, we address a fundamental and unanswered question in microbial ecology: 'When do we need to understand microbial ...
The anionic surfactant linear alkylbenzene sulfonate (LAS) may inhibit soil microorganisms and may occur in agricultural soil through the application of sewage sludge. For five microbial parameters (microbial biomass C and the potentials of iron reduction, ammonium oxidation, dehydrogenase activity, and arylsulfatase activity), we compared the effects of aqueous LAS and LAS-spiked sewage sludge...
Linear alkylbenzene sulfonates (LAS) may occur in sewage sludge that is applied to agricultural soil, in which LAS can be inhibitory to biological activity. As a part of a broader risk assessment of LAS in the terrestrial environment, we tested the short-term effects of aqueous LAS on microbial parameters in a sandy agricultural soil that was incubated for up to 11 d. The assays included 10 mic...
Soil microorganisms play key roles in ecosystem functioning and are known to be influenced by biotic and abiotic factors, such as plant cover or edaphic parameters. New Caledonia, a biodiversity hotspot located in the southwest Pacific, is one-third covered by ultramafic substrates. These types of soils are notably characterised by low nutrient content and high heavy metal concentrations. Ultra...
Background and Objective: Nowadays, swimming pools as a sport and entertainment center have found more popularity. Violation of health based standards in terms of physicochemical, microbial and environmental health indices can turn pools into a potential source of disease transmission and spread. Due to the importance of maintaining swimmers’ comfort, health, and safety, the present study was a...
This study examined the effects of soil physicochemical properties (including heavy metal pollution) and vegetation parameters on soil basal respiration, microbial biomass, and the activity and functional richness of culturable soil bacteria and fungi. In a zinc and lead mining area (S Poland), 49 sites were selected to represent all common plant communities and comprise the area's diverse soil...
Inoculation of leguminous seeds with bioinoculants has been practiced in agriculture for decades to ameliorate grain yield by enhanced growth parameters and soil fertility. However, effective enhancement of plant growth parameters results not only from the direct effects these bioinoculants impose on them but also from their non-target effects. The ability of bioinoculants to reduce the applica...
the aim of the present study was to evaluate the pattern of vancomycin administration in the hematology-oncology ward of nemazee hospital, shiraz, iran. study criteria were developed to assess the several parameters involved in vancomycin therapy. these parameters include the appropriateness of drug usage, dosage, duration of therapy, monitoring for toxicity and serum concentration monitoring. ...
