“…Selection of new bacterial strains. In an attempt to increase the efficiency and stability of the treatment, 22 thermophilic bacterial strains originating from different sources were isolated after incubation of the samples for 2 weeks in swine waste with thermophilic treatment (Table 1) were gram-variable bacilli of different sizes. The presence of spores was observed for 17 strains; 12 were mobile; 21 could grow at 60°C, 9 could grow at 65°C, and none of the strains tested grew at 70°C.…”

“…Aerobic thermophilic treatment has been applied to sewage sludge and animal waste (12,13,22,23). Significant advantages of aerobic thermophilic digestion have been thought to include increased rates of oxidation, resulting in smaller digester volume requirements; destruction of most pathogenic bacteria, viruses, and parasites; weed seed destruction, and increased ease of liquid-solid separation (15).…”

“…11 days, followed by slower reduction of COD (95%) over 11 COD 51-54 000 m da s. Final: pH 8. 3 Presence of phenol reduced bacterial numbers (total viable counts, COD 1600 mg/I TVC) but remaining organisms degraded it using phenol mono TOC 600em e and TVC rose a ain. Three distinct eflluents were produced by different stages in the manufacturing process.…”

“…Air is exhausted through a pipe at the top. The random microflora, which develops in such digesters, responds with rapid growth and typically the temperature is elevated (to a maximum of 70e° C) by self heating (3,4,5]. The organic component of the feedstock is used for microbial growth but most is exhausted as CO 2 , some ammonia and water.…”

“…Sonnleitner and Fiechter (1983a,b)studied the microbiology of sewage sludge undergoing TAD at 50–67°C and characterized at least 95% of the isolates as Bacillus spp. with maximal growth temperatures in excess of 70°C.…”
