| Summary: | <p dir="ltr">This study evaluated the influence of different carbon sources on purple non-sulphur bacteria (PNSB) biofilm formation, and the production of <u>polyhydroxybutyrate</u> (PHB) and other value-added bio-products. Higher PNSB growth and biofilm formation were observed in fuel-synthesis wastewater (FSW), followed by acetate. Both FSW and acetate cultures contained a large proportion of <u>Rhizobiales</u>, while sugar substrates led to yeast enrichment. Protein contents reached 40–41 % for acetate, which is suitable for <u>single cell protein</u> (SCP) use. The maximum PHB content from the suspended and biofilm growth was obtained from glucose (18.1 ± 0.10 %, 12.9 ± 1.11 %), followed by FSW (14.9 ± 0.25 %, 11.2 ± 0.50 %). FSW showed the highest overall productivity for both protein and PHB. Pigment concentrations were low for all substrates. The study underscores substrate influence on <u>microbial community</u> and <u>bioproducts</u> potential. It highlights FSW as a promising substrate for PNSB, suggesting its treatment integration for resource recovery.</p><h2 dir="ltr">Other Information</h2><p dir="ltr">Published in: Bioresource Technology Reports<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.biteb.2024.101945" target="_blank">https://dx.doi.org/10.1016/j.biteb.2024.101945</a></p> |
