in this research, a plot consisting of two sequencing batch reactors (sbr) both reactors were anaerobic stageand its aeration time was had the primary anaerobic stage witling change inthe'touilr:eaction time (9.5 hours).the average concentration of influent phosphorus and rector were 7.5 and 800 miligram per litre respectively. in two months periods the average effeciencies of phosphorus r...
BACKGROUND AND OBJECTIVES Anaerobic bacteria are recognized as important pathogens in surgical infections. However, they are the most overlooked microorganisms by the clinic and the laboratory because of the tedious culture techniques with longer turn-around times. The study was aimed to analyze the frequency of anaerobic bacterial surgical infections and their predisposing factors. MATERIALS...
BACKGROUND Practising the martial art of taekwon-do (TKD) has been proposed to have beneficial effects 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 ...
The present study investigates the influence of individual and combined hydrogen peroxide and thermal pre-treatment of waste activated sludge on anaerobic digestion. For so doing, it employs anaerobic batch reactors in the mesophilic conditions. For comparison, soluble fractions of organic matter, biogas production, biochemical methane potential, removal of chemical oxygen demand (COD), and vol...
The purpose of the study was to compare anaerobic power and anaerobic capacity test scores between young active men and women. Three performance measures of anaerobic power and two of anaerobic capacity were administered to a sample comprising 52 male and 50 female college students (means age = 21.4 yrs). Results indicated significant differences between men and women in body height, weight and...
Table 1. Average colony size of the six quality control strains: Anaerobic chambers and anaerobic jars are used to provide ancomparison of four methods for cultivating anaerobic bacteria. aerobic conditions required to cultivate anaerobic bacteria. All operations and manipulations of cultures can be carried out inside Setup: incubation the anaerobic chamber, thus avoiding any exposure to oxygen...
I was very interested to read the letter of Dr Waitkins et al on the importance of Streptococcus milleri. We too isolate the organism from cases of empyema from time to time and would agree about the importance of S milleri in this context. Although we welcome this reminder about the pathogenicity of the organism, there is one aspect of the letter that could be misleading: S milleri apparently ...
conclusions the results of the present study suggest that the presence of fusobacterium species in periodontal pockets is an important risk factor for halitosis. results in total, 26% (n = 13) and 8% (n = 4) samples were positive for fusobacterium species in the halitosis and control groups, respectively, with f. nucleatum present in the greatest proportion in both groups. halitophobia was sign...
Recent data indicate that cystic fibrosis (CF) airway mucus is anaerobic. This suggests that Pseudomonas aeruginosa infection in CF reflects biofilm formation and persistence in an anaerobic environment. P. aeruginosa formed robust anaerobic biofilms, the viability of which requires rhl quorum sensing and nitric oxide (NO) reductase to modulate or prevent accumulation of toxic NO, a byproduct o...
