The anaerobic biodegradation of surfactants is used as an acceptability criterion in some environmental pieces of legislation (eco-label, risk assessment, etc.), without a proper evaluation of the relevance of such a characteristic. Available screening test methods to assess the anaerobic biodegradation do not simulate the real conditions prevailing in these anaerobic compartments but rather re...

BACKGROUND Surgical Site Infections (SSIs) are infections of incision or deep tissue at operation sites. These infections prolong hospitalization, delay wound healing, and increase the overall cost and morbidity. OBJECTIVES This study aimed to investigate anaerobic and aerobic bacteria prevalence in surgical site infections and determinate antibiotic susceptibility pattern in these isolates. ...

The pyruvate formate-lyase (pfl) gene of Escherichia coli is transcribed from seven promoters which are coordinately induced 12- to 15-fold by anaerobiosis. The FNR protein plays a major role in the anaerobic control of this system. A mutation in the fnr gene, however, only reduces anaerobic induction fivefold, indicating that FNR is not the only factor involved in the anaerobic activation proc...

Municipal sewage is the main exposure route for antibiotics that are used in human medical care. Antibiotics that adsorb to the primary sludge and/or sur-plus activated sludge will enter the anaerobic digesters of municipal sewage treatment plants. Here anaerobic biodegradation or inhibition of anaerobic bacteria resulting in a disturbance of the process might occur. ISO standards 13641 (2003) ...

This study was designed to assess the validity of Conconi’s method, by means of heart rate and lactate threshold measurements to predict anaerobic threshold. The results presented in this paper, clearly demonstrate significant difference between anaerobic threshold values obtained by means of Conconi’s test (Conconi’s threshold) and anaerobic threshold values obtained by direct lactate blood co...

Background—Practising the martial art of taekwon-do (TKD) has been proposed to have beneficial eVects on cardiovascular fitness as well as general physical ability. Furthermore, TKD masters and participants have promoted TKD as a total fitness programme. Research studies substantiating this, however, seem to be lacking, perhaps because TKD is recognised more as a method of self defence than a f...

This study aims to isolate and characterize efficient biohydrogen generating facultative anaerobic bacteria from various samples, viz., biogas plant (BGP), municipal sewage (MS), dairy industry treatment (DTP). The physicochemical properties of untreated sludge samples reflect the anoxic state appropriateness substrate for separating bacteria. producing bacterial strains were separated methanog...

The development of WWTP in business activities needs to pay attention getting appropriate that is more valuable support sustainable development. This study aims evaluate two systems integrated biological WWTP; anaerobic-wetland, and anaerobic-aerobic-wetland, including the effectiveness pollutant removal, operational maintenance, estimation carbon emissions. performance removal was evaluated by...

the cane alcohol vinasse assessment on the removal efficiency of a fixed biomass anaerobic reactor (fbar) was evaluated. crude vinasse was used to feed the reactor. the fbar was operated with organic load rate (olr) of 0.5, 1, 3 and 6 gcod/l/d. removal efficiencies of 85, 82, 75 and 66 per cent were observed respectively. the fba reactor presented an excellent removal of organic matter, however...
