An efficient method reported is to enrich a PHA-producing community in an aerobic feast\/anoxic famine enrichment strategy. This work evaluated the effect of different C\/N feed ratios of 3.5, 2 and 1 g COD\/g N.   <\/p>\n\n<p>The study was executed on a pilot plant scale with municipal excess sludge as an organic carbon source. System performance in PHA production was monitored over the three experimental periods characterised by the different C\/N ratios. Preliminary results show that a lower C\/N ratio decreased the PHA production (20, 24 and 26% w\/w of PHA produced, for COD\/N ratios of 1, 2 and 3.5 g COD\/g N respectively).   <\/p>\n\n<p>Metataxonomic analysis revealed an increase of PHA producers\u2019 microorganisms at the ratio of 3.5 g COD\/g N. The insights gained from the study demonstrate the negative effect of low C\/N ratios on PHA production. Moreover, the metataxonomic proved to be useful in highlighting relationships between operating conditions, microbiota, and the achievement of specific outputs. <\/p>\n\n<p>Read more at: <a href=\"https:\/\/link.springer.com\/chapter\/10.1007\/978-3-031-63353-9_74\">https:\/\/link.springer.com\/chapter\/10.1007\/978-3-031-63353-9_74<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Di Leto Y., Capri F.C., Mineo A., Mannina G., Alduina R., Gallo G.
