Twenty six anaerobes were recovered from 150 deep-seated abscess samples cultured by the proposed two-step combustion-modified candle-jar system and Anoxomat. The degree of growth and colony size were similar in both systems, except for Clostridium difficile. The modified candle-jar system was found to be a sensitive and cost-effective alternative that might be used in resource-limited settings.

An anaerobic culture capable of dechlorinating polychlorinated biphenyls was subcultured under strict anaerobic conditions on solid media containing sterilized river sediment. The dechlorination activity was transferred as a bacterial colony on a solid medium three times. After two transfers on solid medium, the culture was no longer methanogenic but still dechlorinated a mixture of tri- and te...

Background. The evidence indicates that physical activity increases memory and ability to learn in human and animal. That is to say, the brain remarkably responds to exercise. Objectives. The purpose of this study is to investigate the effect and comparison of anaerobic and aerobic exercise on memory. Methods. In this study, ninety male students were randomly divided into three equal gr...

In this study treatment of palm oil mill effluent was carried out with the intention to produce hydrogen during the anaerobic degradation process. The hydrogen generating microflora was isolated from the cow dung based on pH adjustment (pH 5) coupled with heat treatment (2 h). The microflora was initially tested for its hydrogen generating capability for varying fermentation pH of 4, 5, 6 and 7...

‎in this paper‎, ‎the notion of the radical of a filter in‎ ‎residuated lattices is defined and several characterizations of‎ ‎the radical of a filter are given‎. ‎we show that if f is a‎ ‎positive implicative filter (or obstinate filter)‎, ‎then‎ ‎rad(f)=f‎. ‎we proved the extension theorem for radical of filters in residuated lattices‎. ‎also‎, ‎we study the radical‎ ‎of filters in linearly o...

in this study 100 cases of advanced periodontitis were compared with a control group of 100 persons. the parameters were the depth of the periodontal pockets, radiographic images, presence of inflammatory cells and different types of anaerobic bacteria in the pockets. the depth of pocket was measured by a sterile probe and the presence of inflammatory cells was determined through sterile curett...

in this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. in designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. the initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...

background: in this study, the inhibition rate of different oil concentrations containing pcbs (1242 and 1254 pcb arochlors) on the anaerobic biomass was investigated by specific methanogenic activity using the vials with volume of 120 ml. methods: original samples were divided into two groups: with soil containing pcbs and without pcbs and the control samples in both cases were just contained ...

anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...
