“…Changes in the ORP were closely related to the presence of available TOC S . Despite continuous aeration, there was a steep decline in the ORP during the initial stage of treatment, which can likely be attributed to the increasing consumption of DO by aerobes (Hissett et al. 1982; Ndegwa et al.…”

Aims: This study aimed to characterize microbial community dynamics in aerated cow manure slurry at different aeration intensities. Methods and Results: Batch aerobic treatments were set up in 5‐l jar fermentor, each containing 3 l of manure slurry; the slurries were subjected to low, medium and high (50, 150 and 250 ml min−1, respectively) aeration for 9 days. Microbial community composition was determined using terminal restriction fragment length polymorphism and a clone library targeting 16S rRNA genes. High and medium aeration accelerated organic carbon degradation in parallel with the degree of aeration intensity; however, 90% of the initial total organic carbon was retained during low‐aeration treatment. During the active stages of organic carbon decomposition, clones belonging to the class Bacilli accumulated. Moreover, Bacilli accumulation occurred earlier under high aeration than under medium aeration. Conclusions: Organic matter degradation was mainly governed by a common microbial assemblage consisting of many lineages belonging to the class Bacilli. The timing of community development differed depending on aeration intensity. Significance and Impact of the Study: This study reports on changes in several environmentally important parameters and the principal microbial assemblage during the pollution‐reducing phase of cattle manure aeration treatment.

“…In the initial stage of the process, a steep decline in ORP (−350 mV) was observed despite continuous aeration. The decline in ORP was thought to be attributable to the increasing consumption of dissolved oxygen (DO) by the micro‐organisms (Hissett et al. 1982; Ndegwa et al.…”

Aims: To study the microbial community responsible for the reduction of the polluting load during aerobic digestion of pig slurry. Methods and Results: We analysed bacterial succession by nonculture‐based methods and determined the physicochemical parameters and polluting substances during 6 days of aerobic digestion. The bacterial subpopulations evolved by aeration, predominantly Bacillus spp., degraded organic matter and vigorously consumed oxygen, as indicated by low oxidation–reduction potential (ORP). In this phase, the volatile fatty acid (VFA) levels drastically decreased, and VFAs were almost depleted on day 4. Simultaneously, the ammonia concentration decreased to its lowest level on day 4; thereafter, it increased until the end of the process. After the decrease in the total organic carbon content in the supernatant of the decomposed slurry, the ORP increased (∼0 mV), and the microbial community showed an abundance of lineages belonging to the phylum Proteobacteria. Conclusions: Bacillus was the predominant member of the bacterial community driving the VFA‐removal process. Their predominance was related to the presence of available carbon, including VFAs and changes in ORP. Significance and Impact of the Study: Information on the relationships among the involved microbes, polluting materials and physicochemical parameters will aid process design and retrofitting of the process.

“…For example, Couillard and Zhu (1993) reported a higher maximum specific utilization rate of substrate (slaughterhouse effluent) at 58 8C whereas LaPara et al (2000) found no significant difference between 25 and 65 8C with a synthetic wastewater. With pig manure, Hissett et al (1982) made respirometric measurements using bacterial consortia adapted to temperatures between 5 and 50 8C. They reported the results as an Arrhenius plot that showed a typical straight line with a positive slope between 5 and 40 8C; however, after that, the slope become negative and an optimum appears around 45 8C (Fig.…”
