Nanosized zero-valent iron (nZVI) is an effective land remediation tool, but there remains little information regarding its impact upon and interactions with the soil microbial community. nZVI stabilised with sodium carboxymethyl cellulose was applied to soils of three contrasting textures and organic matter contents to determine impacts on soil microbial biomass, phenotypic (phospholipid fatty...

The hyporheic zone of a river is nonphotic, has steep chemical and redox gradients, and has a heterotrophic food web based on the consumption of organic carbon entrained from downwelling surface water or from upwelling groundwater. The microbial communities in the hyporheic zone are an important component of these heterotrophic food webs and perform essential functions in lotic ecosystems. Usin...

This study was carried out during 2004 and 2005 seasons on eight years old Arabi pomegranate trees grown in sandy soil to investigate the influence of microbial biofertilization on tree growth, yield, fruit quality and leaf minerals content. Microbial inoculum (Azotobacter spp. Azospirillum spp. and Bacillus megatherium which found in (Biogein, Nitrobine, phosphorein), in addition, arbuscular m...

Microbial metagenomes are DNA samples of the most abundant, and therefore most successful organisms at the sampling time and location for a given cell size range. The study of microbial communities via their DNA content has revolutionized our understanding of microbial ecology and evolution. Iron availability is a critical resource that limits microbial communities' growth in many oceanic areas...

Ruminal microbial fermentation plays an essential role in host nutrition, and as a result, the rumen microbiota have been a major focus of research examining bovine feed efficiency. Microbial communities within other sections of the gastrointestinal tract may also be important with regard to feed efficiency, since it is critical to the health and nutrition of the host. The objective of this stu...

Microbial mats situated at the Manikaran hot springs (>95°C) are characterized by their high arsenic content (140 ppb), qualifying as a stressed niche. Here, we report the annotated draft genome (3.85 Mb) of Cellulosimicrobium sp. strain MM, isolated from these microbial mats, consisting of 3,718 coding sequences, with an average % G+C of 74.4%.

In order to estimate the microbial biomass content and to quantify the amount of available plant nutrients derived from microbial biornass in Bangladesh soils, biomass-C, -N, and available-N eoptents using samples from 8 soils were measured by applying the chloroform fumigation and drying-rewetting methods, respectively. 1)

The purpose of this study was to establish the effects of ultrasonic treatment of eggs on egg weight loss, hatchability, tibia mineral content, chick performance, and eggshell microbial activity. A total of 600 fresh eggs was randomly divided into 5 groups. Treatments were no ultrasound, 35 kHz for 5 min, 35 kHz for 10 min, 35 kHz for 15 min, and eggs sprayed with benzalkonium chloride solution...

The standardization of Leaves of Mallotus philippensis (Lam.) Mull. Arg. was carried out according to the quality control methods suggested by WHO. The powder material was tested for various parameters like macroscopy, microscopy, foreign matter, ash value, extractable matter, crude fibre content, moisture content, swelling index, foaming index, pesticide residues, Arsenic and heavy metals, mic...

Shredded carrots in modified atmosphere packaging were treated with low-dose irradiation of 0.5 kGy in order to determine whether additional reduction of microbial population would be achieved for carrots previously treated with chlorine. Commercially prepared shredded carrots treated with irradiation had a mean microbial population of 1300 CFU/g at the expiration date (9 days after irradiation...
