the objective of this research was to study the feasibility of a two stage continuous system employing anaerobic-aerobic microbial film for domestic wastewater treatment and the effect of iron on the behavior of sulfate reducing bacteria in anaerobic metabolism. a bench scale system with an anaerobic filter followed by aerobic fixed units used plastic media and was operated in up flow manner wi...
improving anaerobic performance and anaerobic power is the critical aspect on successfully in competitions for many athletes. the purpose of current research was to investigating the effect of various pre-competitions warm-up on anaerobic performance. it has been shown that, differences pre-competitions activity may effect on anaerobic and explosive performance. effect of general warm-up, witho...
conclusions: in the present study, we have figured out that a number of the important anaerobic infections treatment antibiotics have lost partly or totally their effectiveness on b. fragilis. background: bacteroides fragilis are among the most important anaerobic bacteria behind most of the anaerobic infections. they have acquired resistance to essential treatment antibiotics of anaerobic infe...
unless anaerobic reactor and digesters have been applied worldwide, suitable operation is still challenging. threats of facing with low efficiency operationally, their sensitivity and souring phenomenon are part of typical problems. in this article, the application of electrolysis as an upgrading alternative is investigated for the purpose of controlling its capability on effluent quality promo...
Community Level Physiological Profiles (CLPP) is novel method to evaluate microbial activity and diversity in ecosystems. According to the previous findings, poly-β-hydroxybutyrate (PHB) as a bio-control product, increases bacterial diversity in some aquatic animals. In this study, the effects of four experimental diets (control, combination of two PHB degrading bacteria, 2% PHB, bacteria+ 2% P...
background: to determine prospectively the prevalence of anaerobic and aerobic infection in early onset (during 72 hours of age) neonatal sepsis, in tehran vali-e-asr hospital. methods: among all the live birth, neonates suspecting of having septicemia were investigated for isolation of microorganisms. culture bottle containing enriched tryptic soy broth was used for standard blood culture sys...
in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas p...
Abstract Background and objectives: Anaerobic microorganisms, particularly bacteroides play an important role in causing Pulp and preapical diseases that lead to chronic abscess. we aimed at studying anaerobie infections in necrotic teeth having Acute and chronic clinical symptoms. Material and Methods: We examined 28 necrotic teeth of 28 patients for the purpose of anaerobic culture fifteen ca...
It is now generally recognized that anaerobic bacteria may be involved in most human bacterial infections that follow any form of surgery or are related to those body sites that have a large anaerobic population. Anaerobes must therefore be sought in a wide variety of clinical specimens. In this study, 3015 specimens of patients (1684 male and 1331 female) with periodontitis (160 cases), abcess...
