Abstract：
:Purple phototrophic bacteria (PPB) have been proposed as a high-growth, assimilative option for wastewater treatment. The original partition-release-recover concept proposal requires their near complete digestion and release (and subsequent recovery) of energy and nutrients in an anaerobic digester. While the growth (partition) step has been extensively assessed, no work has been done on their anaerobic digestion characteristics (release). Continuous mesophilic (20d) and thermophilic (10d) digestion could achieve around 55% volatile solids degradation (VSD), with 35% (mesophilic) and 20% (thermophilic) nitrogen solubilisation. Post digestion (with/without pretreatment) could increase the VSD to 70% and nitrogen solubilisation to 43%. A number of pretreatment options were tested, with high temperature and sonication being relatively effective, and chemical treatment, and temperature phased digestion being relatively ineffective vs controls. Overall, anaerobic digestion of PPB results in substantial residual particulate material, with an increased nitrogen content, and avenues to effectively utilise this residue should be identified.
