Polyhydroxyalkanoate (PHA) production was achieved using tomato cannery waste coupled with a mixed microbial culture during wastewater treatment. The two‐stage PHA production process comprised a sequencing batch reactor (SBR), operating under a periodic feast–famine regime, to accomplish simultaneously wastewater treatment and selection of PHA‐accumulating microbes, followed by a batch reactor for the production of PHA‐rich biomass. The SBRs were efficient at removing soluble carbon (84… 

Sludge minimization in municipal wastewater treatment by polyhydroxyalkanoate (PHA) production

The proposed approach to link polyhydroxyalkanoates (PHA) production with sludge minimization in municipal wastewater treatment has a good potential especially if coupled to minimization of both primary sludge and excess secondary sludge.

PHA production by mixed cultures: a way to valorize industrial waste

The effectiveness of polyhydroxyalkanoates (PHA) production process includes a first stage of Mixed Microbial Culture (MMC) selection. This step determines the success of subsequent PHA accumulation

Process Development of Polyhydroxyalkanoates Production by Halophiles Valorising Food Waste

This study established a novel production system of PHA from food waste through halophilic microbial fermentation with spent medium recycling, and successfully reused for four consecutive batches and provided consistent PHA concentrations and product qualities.

Bioconversion of Organic Pollutants in Fish-Canning Wastewater into Volatile Fatty Acids and Polyhydroxyalkanoate

It can be seen that the acidification of fish-canning wastewater is possible even at high saline concentrations (27.7 g NaCl/L), and the enrichment and accumulation results show promising news and which direction has to be followed: PHAs can be obtained from challenging substrates, and the feeding mode during the accumulation stage has an important role to play when it comes to inhibition.

Economical analysis seemed to suggest the PHA produced from the food waste could be an alternative material to produce the biodegradable plastic to be used for the collection bags for solid waste.

Optimal production of polyhydroxyalkanoates in activated sludge biomass

In this study, actiated sludge microorgan isms from a conventional wastewater treatment process were induced, by control-ling the carbon: nitrogen (C:N) ratio in the reacorliquor, to accumulate PHAs and an intermittent nitrogen feeding program was established to optimize the volumetric PHA productivity in a wastewaterreatment process.

Enrichment of activated sludge in a sequencing batch reactor for polyhydroxyalkanoate production.

Observations by fluorescence microscopy showed that the majority of microorganisms in the enriched biomass could be stored and were identified among the numerically most representative genera in the enrichment biomass.

Biodegradable polymers from organic acids by using activated sludge enriched by aerobic periodic feeding.

A new process based on the aerobic enrichment of activated sludge to obtain mixed cultures able to store PHAs at high rates and yields is described, which seemed to indicate that, on removing the substrate mixture for copolymer production, propionic acid was fully utilized to produce propionyl coA, whereas the acetylCoA was fully provided by acetic and lactic acid.

Aerobic production of activated sludge polyhydroxyalkanoates from nutrient deficient wastewaters.

The molecular weight and melting point of the PHA produced were found to be in a desirable range with respect to material properties, which have not been well studied in the previous literature for mixed cultures.

Recovery of biodegradable plastics from activated sludge process

In this research, PHA (polyhydroxyalkanoate) production system by activated sludge was studied. PHA behaves as carbon and energy storage material in bacteria. And PHA is a biodegradable plastic when

Production of polyhydroxyalkanoates by mixed microbial cultures

The mechanisms of storage, metabolism and kinetics of mixed cultures for PHA production by mixed cultures are studied and an overview and discussion of various mechanisms and processes is presented.

A Proposal for Zero Emission from Palm Oil Industry Incorporating the Production of Polyhydroxyalkanoates from Palm Oil Mill Effluent

In our previous reports, we have described the production of organic acids from palm oil mill effluent (POME) which were used as fermentation substrates to produce polyhydroxyalkanoates (PHA). Here

Optimization of polyhydroxybutyrate production by mixed cultures submitted to aerobic dynamic feeding conditions

Activated sludge submitted to aerobic dynamic feeding conditions showed a good and stable capacity to store polyhydroxybutyrate (PHB) and a microbial population with a high PHB storage capacity was selected.
