Polyhydroxyalkanoates (PHA) production from waste streams using mixed microbial cultures (MMC) can unlock the potential of PHA to substitute oil-based plastics. However, these processes are still at low technology readiness level (4–6). Demonstrating a better environmental performance would boost their deployment industrial scale. Hence, including guidance during development, when there opportu...
BACKGROUND Cyanide is one of the most toxic chemicals produced by anthropogenic activities like mining and jewelry industries, which generate wastewater residues with high concentrations of this compound. Pseudomonas pseudoalcaligenes CECT5344 is a model microorganism to be used in detoxification of industrial wastewaters containing not only free cyanide (CN(-)) but also cyano-derivatives, such...
BACKGROUND The substitution of plastics based on fossil raw material by biodegradable plastics produced from renewable resources is of crucial importance in a context of oil scarcity and overflowing plastic landfills. One of the most promising organisms for the manufacturing of medium-chain-length polyhydroxyalkanoates (mcl-PHA) is Pseudomonas putida KT2440 which can accumulate large amounts of...
The goal of this research is to optimize PHA production in the syngas fermenting organism Rhodospirillum rubrum. Syngas fermentation is the hybrid thermochemical/ biological approach to processing biomass into valuable fuels and chemicals. The process begins with the gasification of biomass to produce syngas, a flammable gas mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), a...
The recovery of biopolymers from sewage sludge could be a crucial step in implementing circular economy principles wastewater treatment plants (WWTP). In this frame, the present study was aimed at evaluating simultaneous production polyhydroxyalkanoates (PHA) and extracellular polymeric substances (EPS) obtainable agro-industrial wastewater. Two biological enrichment systems, aerobic granular (...
Seven strains of sulfate-reducing bacteria (SRB) were tested for the accumulation of polyhydroxyalkanoates (PHAs). During growth with benzoate Desulfonema magnum accumulated large amounts of poly(3-hydroxybutyrate) [poly(3HB)]. Desulfosarcina variabilis (during growth with benzoate), Desulfobotulus sapovorans (during growth with caproate), and Desulfobacterium autotrophicum (during growth with ...
Polyphosphate accumulating organisms (PAOs) belong mostly to Proteobacteria and Actinobacteria and are quite divergent. Under aerobic conditions, they accumulate intracellular polyphosphate (polyP), while they typically synthesize polyhydroxyalkanoates (PHAs) under anaerobic conditions. Many ecological, physiological, and genomic analyses have been performed with proteobacterial PAOs, but few w...
