Four typical antibiotics were added to human feces for aerobic composting using batch reactors with sawdust as the bulk matrix. Under three composting temperatures (room temperature, 35 ± 2 °C and 55 ± 2 °C), decreases in the extractable concentrations of antibiotics in the compost were monitored for 20 days. As a result, the removals of extractable tetracycline and chlortetracycline were found to be more temperature-dependent than the removals of sulfadiazine and ciprofloxacin. However, more than 90 % of all of the extractable antibiotics were removed at 55 ± 2 °C. Three specific experiments were further conducted to identify the possible actions for antibiotic removal, including self-degradation in aqueous solution, composting with a moist sterile sawdust matrix without adding feces and composting with human feces and moist sterile sawdust. As a result, it was found that the removal of tetracycline and chlortetracycline was mainly due to chemical degradation in water, whereas the removal of sulfadiazine was mainly attributed to adsorption onto sawdust particles. The microbial activity of compost varied with temperature to a certain extent, but the differences were insignificant among different antibiotics. Although microbial action is important for organic matter decomposition, its contribution to antibiotic degradation was small for the investigated antibiotics, except for ciprofloxacin, which was degraded by up to 20 % due to microbial action.

“…This may be the result of a reduction in N loss during acidulocomposting under acidic conditions, as reported by Asano et al (2010). The C content was also higher in AC than in the other composts.…”

“…The acidulocomposting facility has devices for heating, mixing, and ventilating and can automatically keep temperatures between 50 and 70 °C and maintain acidic conditions (pH 3.5-6.5) via the production of lactic acid by thermophilic lactic acid bacteria (Asano et al, 2010;Hemmi et al, 2004) for more than 2 yr, with very low odor emissions and little labor needed during the process (Nishino et al, 2003). The acidulocompost (AC) produced is acidic (typically pH 4.5-5.5) and has a caramel-like and weakly burnt smell (Nishino et al, 2003).…”

“…Gaseous N losses during the composting of livestock manures and sewage sludge under alkaline conditions are potentially high, with reported values of approximately 46-77% (Witter & Lopez-Real, 1988) and more than 60% (Martins & Dewes, 1992) of the total N in the raw materials. Because acidulocomposting proceeds under acidic conditions, N losses through ammonia volatilization are very low (Asano et al, 2010). Therefore, the acidulocomposting method may decrease ammonia volatilization and air pollution and increase the compost's N content.…”

“…In acidulocomposting, lactic acid bacteria such as Lactobacillus and Pediococcus species are the major contributors throughout the composting process, and PCR-based studies have demonstrated the presence of unidentified micro-organisms (Hemmi et al, 2004;Haruta et al, 2005;Asano et al, 2010;Suematsu et al, 2012). However, little has been reported on novel bacteria from acidulocompost.…”

A thermophilic and phospholipid-degrading bacterium, designated strain B157 T , was isolated from acidulocompost, a garbage compost processed under acidic conditions at moderately high temperature. The organism was Gram-stain-positive, aerobic, spore-forming and rod-shaped. Growth was observed to occur at 40-65 C and pH 4.8-8.1 (optimum growth: 50-60 C, pH 6.2). The strain was catalase-and oxidase-positive. The cell wall contained meso-diaminopimelic acid, alanine, glutamic acid and galactose. The predominant respiratory quinone was menaquinone-7 (MK-7) and the major fatty acids were anteiso-C 17 : 0 and iso-C 17 : 0 . Comparative 16S rRNA gene sequence analysis showed that strain B157 T was related most closely to Tuberibacillus calidus 607 T (94.8 % identity), and the phylogenetic analysis revealed that it belonged to the family Sporolactobacillaceae. The DNA G+C content was determined as 51.8 mol%. In spite of many similarities with the type strains of members of the family Sporolactobacillaceae, genotypic analyses suggest that strain B157 T represents a novel species of a new genus, Caenibacillus caldisaponilyticus gen. nov., sp. nov. The type strain of Caenibacillus caldisaponilyticus is B157 T (=NBRC 111400 T =DSM 101100 T ).
