The GreenLight® system was designed for applications across the food industry with further uses in environmental measurements. The core technology is a novel oxygen-depletion sensor that can detect very small changes in oxygen content making the system ideal for use in enumerating aerobic microbes. Here we describe a small comparative study conducted by Luxcel Biosciences, assessing correlation...

silver nanoparticles with size of 6- 57nm were synthesized by bioreduction method from anisochilus carnosus aqueous and ethanolic extract. biosynthesized nanoparticles showed maximum antimicrobial activity against k. pneumonia (13±1.67mm), e.coli (13±1.97mm) and b. subtilis (13±1.07mm) followed by p. aeruginosa and minimum against s. aureus. the quantitative formation, characteristics and impur...

The findings of a series of studies investigating the clogging of leachate collection and drainage systems for municipal landfill sites are described. Batch tests, column studies, and field-scale “mesocosm” test cells were used to study the development of a thick microbial biofilm covering the surfaces and filling the pore space of the granular drainage media. Within this biofilm, anaerobic mic...

Raw milk is a valuable food which its quality is important regarding both milk consumption itself and manufacturing of other dairy products. The aim of this study was to investigate the effect of different seasons on the variations of raw milk composition. To do so different samples of raw milk were taken during summer and winter from Qazvin province and their physicochemical properties includi...

Microbial Fuel Cells (MFCs) are capable of producing electricity while cleaning wastewater. This novel technology can replace energy-consuming aerobic treatment even if low effluent concentrations are demanded. The goal of this work is to optimize a MFC-based wastewater treatment process. A MFC mathematical model, which accounts for co-existence of methanogenic and anodophilic microbial populat...

the aim of this study was to determine and scrutiny about chemical compounds and microbial load changes of broiler chicks’ diet due to gamma irradiation processing. there were 12 broiler chicks’ diets weighting one kg that including 4 packs from starter period, 4 packs from grower period and 4 packs from finisher period. feeds were irradiated in four doses including 0, 6.7, 7.7 and 8.7 kilogray...

Background: Colorectal cancer (CRC) is one of the most common cancer types worldwide. The role of the intestinal microbiota in CRC, however, is not well established. In particular, the co-variation between age, tumor progression and microbiota remains largely unknown. Objective and design: We therefore used a recently developed A/J Min/+ mouse model resembling human CRC to investigate how micro...
