a 3 × 2 factorial experiment was conducted to investigate the effect of thymol + carvacrol (0, 100 and 200 mg/kg) on ileal microbial population and jejuna and ileal histomorphology of broilers fed carboxy methyl cellulose (cmc: 0 and 2%) containing diet. each of the 6 dietary treatments was replicated 5 times with 12 chicks each from 0 to 42 days of age. there was no interaction effect of cmc a...

contamination of soil was investigated in this study from the tehran oil refining co. of iran. fifteen soil samples were collected at several points in the azimabad, 15 km south of tehran city, iran. samples were collected at depths of 0–30 cm. control sampleswere prepared to determinebackgroundlevels ofsoil contaminationwithpetroleumhydrocarbonsfor comparison with contaminatedsites. total petr...

this study was conducted to investigate the effects of the medicinal plant yarrow (achillea millefolium l.), a probiotic (primalac) and an antibiotic (virginiamycin) on gastrointestinal tract (git) characteristics, microbial populations, immune response, serum lipids and growth performance of broiler chickens. a total of 250 one-day old male broilers (ross 308) were randomly allocated to 5 trea...

Bacterial biofilms demonstrate resistance in response to antimicrobial stress. This adaptive response is more effective than in the corresponding planktonic populations. The topic of this paper is concerned with an investigation of the longtime behavior of solutions to a biofilm model without growth on domains in Rd (d = 1, 2, 3). This analysis is extended to both planktonic and biofilm systems...

Microbial Population Genetics // 190445559X, 9781904455592 // Jianping Xu // 213 pages // Horizon Scientific Press, 2010 // 2010 Microbial population genetics is a rapidly advancing field of investigation with relevance to many areas of science. The subject encompasses theoretical issues, such as the origins and evolution of species, sex, and recombination. Population genetics lays the foundati...

background: the objective of the study is examining the microbial quality of drinking water in kashan’s villages, and determining the usage of safe water in rural population in terms of microbial quality in the second-half 2007. also the role of kashan rural water and wastewater company (krwwc) in improving drinking water quality in kashan rural areas was investigated. methods: in this descript...

Salted Kutum roe was prepared by soaking in brine to a traditional procedure. Proximate composition (moisture, protein, lipid, pH, ash and salt content), total volatile basic nitrogen (TVB-N), fatty acid profiles and microbiological characteristics of raw and salted roe of Caspian white fish (Rutilus frisii kutum) were determined. The results indicated that protein and moisture contents were si...

The origins of biological complexity in microbial ecosystems are encoded within the collective genomes of the community. Cultivation-independent genomic studies provide direct access to the genomes of naturally occurring microbes, cultivated or not. Genome-enabled approaches are now significantly advancing current knowledge of genome content, diversity, population biology and evolution in natur...

Genetic oscillators are a major theme of interest in the emerging field of synthetic biology. Until recently, most work has been carried out using intra-cellular oscillators, but this approach restricts the broader applicability of such systems. Motivated by a desire to develop large-scale, spatially-distributed cell-based computational systems, we present an initial design for a population-lev...
