low density polyethylene films incorporating different types of organically modified nanoclays were prepared. physical, surface morphology and mechanical properties of the films were analyzed by x-ray diffraction pattern, scanning electron microscopy and tensile strength (ts) and length increase until fracture point (e) parameters, respectively. colony counting method was used to investigate an...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...

the aim of this study was to determine physicochemical, microbial properties and antioxidant activityof fermented camel milk (chal) and introduce it as a functional food. the protein content of thesamples was determined using kjeldahl method and total dry matter using oven drying method. theamount of fat content with gerber method and ph was measured using a ph meter. antioxidantactivity was al...

abstract soil microbiological criteria are a complex reflection of interactive metabolic processes that may not be evaluated only by measuring a single parameter but rather it requires the simultaneous determination of more parameters and combining them. the objective of this research was to study enzyme activities: microbial biomass carbon ratios in salinized and none-saline soils in the prese...

abstract soil microbial activity and biochemical processes are often limited by carbon availability in arid- and semi-arid regions, probably due to the low organic matter content. consequently, return of plant residues to soil is a convenient and effortless practice for increasing microbial activities and biochemical reactions. the primary objective of this study was to evaluate the effect of v...

recently, biosynthesis of nanoparticles has received attention due to an increasing need of developing rapid, simple and ecofriendly protocol. pathogenicity of some of the organisms and lengthy reaction are the drawbacks involved with biosynthesis. we describe a simple protocol for rapid synthesis of silver nanoparticles through biological route using a marine-derived fungus aspergillus niger. ...

the root and flowers of butea monosperma (lam.) were extracted with methanol. extensive chromatographic separation and purification with the organic solvents was done. four phytochemicals were separated and their structures were established based on various spectroscopic techniques. isolated crude extract was subjected for antibacterial activity against gram-negative and gram-positive bacteria ...

the influence of long-term mixed organic and inorganic contamination on soil microbial activity, community structure and genetic diversity was investigated in soil samples from a coke oven plant located in upper silesia, poland. the tested soils were heavily contaminated with polycyclic aromatic hydrocarbons (pahs) and heavy metals. the microbial communities were characterized using the phospho...
