For all aerobic processes under investigation a clear temperature increase in the aerobic reactor was measured because of the exothermal metabolic processes of the aerobic biocenosis. The degradation results obtained are comparable to or better than those of the 20-day digestion (reference process). Sludges treated in two stages in experiments - 7 days of anaerobic treatment and 2 days of aerobic-thermophilic treatment - can be judged to be completely stabilized because of the stabilization parameters BOD/sub 5//COD ratio and respiratory activity. Mesophile anaerobe Klaerschlammstabilisierung mit aerober Folgebehandlung Mesophilic anaerobic stabilization of sewage sludge. Because of an increasing demand for more fresh products, ideally the processing temperatures should be Spores from mesophilic aerobic sporeforming bacteria (Bacillus) are sometimes able to survive the thermal process of commercial sterile products and sporadically cause spoilage or food poisoning. cereus strains, in particular those that produce diarrheal toxins.ĭetecting bacterial spores in soup manufacturing cereus were spice isolates to form spores, produce diarrheal toxins, and grow at moderately abusive temperatures makes retail spices an important potential vehicle for foodborne illness caused by B. thuringiensis spores were isolated from 77 (31%) and 11 (4%) samples, respectively. Samples contained a wide range of aerobic-mesophilic bacterial spore counts (spices had high levels of aerobic spores (> 10(7) CFU/g). This study focused on the levels of aerobic-mesophilic spore-forming bacteria and B cereus spores associated with 247 retail spices purchased from five states in the United States. retail spices with regard to Bacillus cereus. Recent incidents of foodborne illness associated with spices as the vehicle of transmission prompted this examination of U.S. Spore prevalence and toxigenicity of Bacillus cereus and Bacillus thuringiensis isolates from U.S. Of significant note is the high multiple resistance pattern of Bacillus sp. Ife, Osun State, Nigeria and were analysed for aerobic mesophilic bacterial load. Introduction aerobic mesophilic bacteria associated with irish potato The isolated aerobic mesophilic bacteria were phenotypically characterized by biochemical tests and their susceptibility to . Ī total of 15 samples of spoilt Irish potatoes (Solanum tuberosum L.) were collected from five grocery shops in Ile-Ife, Osun State, Nigeria and were analysed for aerobic mesophilic bacterial load. 4 refs., 1 tab.Īerobic Mesophilic Bacteria Associated With Irish Potato ( Solanum. The presence of coliforms irradiated has not been found even in the coroa beans with the dose of 1.05 kGy. The results of this work has shown a considerable reduction of the mesophilic aerobic spore formers in irradiated Brazilian Comun Cocoa beans as long as the irradiation dose was increased from 1.05 to 3.99 kGy. Spore - forming aerobic bacilli have been observed in fermenting cocoa in Jamaica and West Africa. The presence of coliforms in processed foods is an useful indicator of post-sanitization and post processing contamination, and members of the mesophilic aerobic spore formers have great importance in food spoilage.
