“…The experimental data from other SBRs operated in a similar manner (Johnson et al, 2010) were additionally used to validate Equation (9). As can be seen from Figure 5, the experimental data on the PHB content at the end of feast phase can be described by Equation (9) very well.…”

“…The temperature effects on PHA-producing cultures enriched with a feast-famine strategy have been studied by Krishna and van Loosdrecht, 1999 and by Johnson et al, 2010. However, both of these studies mainly studied the influence of temperature on the kinetics of the process.…”

The impact of temperature and cycle length on microbial competition between polyhydroxybutyrate (PHB)-producing populations enriched in feast-famine sequencing batch reactors (SBRs) was investigated at temperatures of 20 1C and 30 1C, and in a cycle length range of 1-18 h. In this study, the microbial community structure of the PHB-producing enrichments was found to be strongly dependent on temperature, but not on cycle length. Zoogloea and Plasticicumulans acidivorans dominated the SBRs operated at 20 1C and 30 1C, respectively. Both enrichments accumulated PHB more than 75% of cell dry weight. Short-term temperature change experiments revealed that P. acidivorans was more temperature sensitive as compared with Zoogloea. This is particularly true for the PHB degradation, resulting in incomplete PHB degradation in P. acidivorans at 20 1C. Incomplete PHB degradation limited biomass growth and allowed Zoogloea to outcompete P. acidivorans. The PHB content at the end of the feast phase correlated well with the cycle length at a constant solid retention time (SRT). These results suggest that to establish enrichment with the capacity to store a high fraction of PHB, the number of cycles per SRT should be minimized independent of the temperature.

“…In this study glucose was selected as carbon source for further studies. There were several reports on PHB production using mixed cultures (Tohyama et al 2000;Johnson et al 2010). In the present study glucose may be converted into lactate by L. delbrueckii NII 0925 and the lactate was in turn converted to PHB by B. sphaericus NII 0838 as an alternative.…”
