“…Operating the SBR at higher volume exchange ratios -increasing the F/M ratio -leads to higher maximum PHA contents in the SBR itself. This was observed in the present study, as well as by Jiang et al (2011a) and Valentino et al (2014). However, it does not necessarily select for the highest PHA storage capacity or for a higher substrate uptake and PHA production rate.…”

“…Although Jiang et al (2011a) reported increasing rates for SBRs operated at cycle lengths increasing from 1 to 12 h, the specific substrate uptake rate in their SBR operated at 18 h cycles was considerably lower again -just as in this study (Table 2). Moreover, Valentino et al (2014) reported decreasing uptake and storage rates for SBRs operated at increasing cycle lengths (2-8 h). For successful PHA production, both high biomass-specific rates and a high PHA storage capacity are important.…”

“…For samples collected during the steady-state period of the SBR with the 8-h cycle, Alphaproteobacteria closely related to Meganema perideroedes were prominent, as well as the increase of Thauera-related phylotype was detected (also present in the early stages of the reactor operation). Valentino et al (2014) observed that shortening the feeding time in the 8-h cycle, from 40 to 10 min, led to an immediate adjustment of the MMC, and once the steady state was reached, Thauera become the dominant bacteria while the previous dominant bacteria related to M. perideroedes disappeared. Also, a progressive increase of Hydrogenophaga sp.…”

“…In order to investigate the effect of cycle length duration in the selection of PHA-storing bacteria, Valentino et al (2014) analyzed the population selected in SBRs with 2-, 6-, and 8-h cycles, all with 1 day of HRT and SRT, fed with a mixture of acetic and propionic acids, up to 8.5 g/L COD and pH controlled at 7.5. Also, the feeding time during the operation with the 8-h cycle was tested.…”
