Sugar Factory effluent is one of the most important moderate – high pollution concentration wastewater, which is generated mainly from the mill house washing activities of the sugar factory. The effluent is rich in organic matter resultant from the sugarcane juice, sugar syrup and sugar present in the washwater. The COD of this effluent is variable from 5000 – 10000 mg/L. The aim of the present...

We compared lactate threshold (TLac) with non-invasive markers of an aerobic-anaerobic transition; namely, ventilatory (VT) and tissue saturation index (TSIT) thresholds. While identification of a breakpoint in blood lactate concentration ([BLa]) is common for determination of an aerobic-anaerobic transition, non-invasive measures, VT and NIRS, have also received attention as a means of determi...

When aerobic microbes deplete oxygen sufficiently, anaerobic metabolisms activate, driving losses of fixed nitrogen from marine oxygen minimum zones. Biogeochemical models commonly prescribe a 1–10 lM critical oxygen concentration for this transition, a range consistent with previous empirical and recent theoretical work. However, the recently developed STOX sensor has revealed large regions wi...

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...

This study assessed the effect of the carbon/nitrogen (C/N) ratio on the hydrogen production from sucrose-based synthetic wastewater in upflow fixed-bed anaerobic reactors. C/N ratios of 40, 90, 140, and 190 (g C/g N) were studied using sucrose and urea as the carbon and nitrogen sources, respectively. An optimum hydrogen yield of 3.5 mol H2 mol-1 sucrose was obtained for a C/N ratio of 137 by ...
