A central pursuit of microbial ecology is to accurately model changes in microbial community composition in response to environmental factors. This goal requires a thorough understanding of the drivers of variability in microbial populations. However, most microbial ecology studies focus on the effects of environmental factors on mean population abundances, rather than on population variability...

Five years after the introduction of denaturing gradient gel electrophoresis(DGGE) and temperature gradient gel electrophoresis (TGGE) in environmental microbiology these techniques are now routinely used in many microbiological laboratories worldwide as molecular tools to compare the diversity of microbial communities and to monitor population dynamics. Recent advances in these techniques have...

Investigation of the Effect Ozone Gas on Microbial Population and Quality Broilers Chicken Diets

in this study, the antimicrobial effect of sea cucumber extract (0.5, 1 and 2%) on the microbial population of rainbow trout fillets during refrigerated storage was examined. fillets were stored for 16 days and every 4 days microbial tests (including total bacterial load, pseudomonas, enterobacteriaceae and h2s producing bacteria) were performed on the samples. results showed that there was no ...
