Marine sediments of coastal margins are important sites of carbon sequestration and nitrogen cycling. To determine the metabolic potential and structure of marine sediment microbial communities, two cores were collected each from the two stations (GMT at a depth of 200 m and GMS at 800 m) in the Gulf of Mexico, and six subsamples representing different depths were analyzed from each of these tw...

synchronization of rumen available protein and energy is one of the conceptual methods to increase the efficiency of utilization of nutrients by the ruminants the concept of synchronization energy and protein was first by jhonson, implying that maximum microbial protein synthesis could be achieved by matching the rate of organic matter and protein degradation. synchronization of rumen available...

Recent studies suggest that nitrogen can have significant effects on microbial activity and carbon storage by causing shifts in fungal:bacterial activity such that bacterial degradation pathways become dominant under high nitrogen conditions. If true, changes in fungal:bacterial (F:B) ratios could have a major impact on carbon storage in urban pollution affected soils that receive high amounts ...

Background: Hand-made cheeses are usually prepared following dissimilar procedures which influence the quality and the organoleptic properties of the products. Objective of the present study was to evaluate how manufacturing season and ripening time affect hand-made Pecorino Abruzzese cheese. Methods: Microbiological and physicochemical characteristics were investigated on raw milk cheeses pro...

While the soil environment is generally acknowledged as playing a role in plant competition, the relative importance of soil resources and soil microbes in determining outcomes of competition between native and exotic plants has rarely been tested. Resilience of plant communities to invasion by exotic species may depend on the extent to which native and exotic plant performance are mediated by ...

Subalpine grasslands are highly seasonal environments and likely subject to strong variability in nitrogen (N) dynamics. Plants and microbes typically compete for N acquisition during the growing season and particularly at plant peak biomass. During snowmelt, plants could potentially benefit from a decrease in competition by microbes, leading to greater plant N uptake associated with active gro...

a three-year field experiment was conducted under conditions of luvic chernozem soil. diversified nitrogen fertilization with 0, 60, 120, and 180 kg n ha-1, and microbial preparations improving soil properties were applied to potatoes, cv. ‘satina’, cultivation. n–no3 concentration in the soil profile (0–0.9 m) in autumn after potato harvesting fluctuated from 28 kg n ha-1 in the n0 treatment t...

introduction ensiling is less dependent to weather condition and farmers are trying to ensile forages for preserving them for livestock feeding. ensiling legumes because of their buffering capacity and high moisture content are difficult. also, ensiling alfalfa will lose up to %85 of its nitrogen content as non-protein nitrogen. adding some additives like carbohydrate sources will improve alfal...

the aim of this study was to evaluate the effects of tannic acid (ta) and pistachio by-product tannin extract (pbe) on n utilization and efficiency of microbial nitrogen synthesis (emns) in saanen dairy goats. the experimental design was a change over design with three treatments and three periods using six mid lactation multiparous dairy goats. tannic acid solution and pbe were added to fresh ...
