The production of polyhydroxyalkanoates (PHAs) by Bacillus megaterium using industrial residues, crude glycerol from biodiesel synthesis and rice hull hydrolysate (RHH), as low-cost carbon sources was investigated. experiments were conducted shaking flasks at 30 °C 180 rpm up to 72 h. extraction PHA carried out sodium hypochlorite make its recovery more environmentally friendly avoiding organic...

The fishing industry produces vast amounts of saline organic side streams that require adequate treatment and disposal. bioconversion resources into value-added products, such as biodegradable polyhydroxyalkanoates (PHAs), has not yet been fully explored. This study investigated PHA production by mixed microbial cultures under 30 gNaCl/L, the highest NaCl concentration reported for acclimatizat...

Nerve guidance conduits (NGCs) are used as an alternative to the “gold standard” nerve autografting, preventing need for surgical intervention required harvest autologous nerves. However, regeneration outcomes achieved with current NGCs only comparable autografting when gap is short (less than 10 mm). In present study, we have developed made from a blend of polyhydroxyalkanoates, family natural...

This work describes the production of polyhydroxyalkanoates (PHA) as a side stream process on a municipal waste water treatment plant (WWTP) and a subsequent analysis of the production potential in Germany and the European Union (EU). Therefore, tests with different types of sludge from a WWTP were investigated regarding their volatile fatty acids (VFA) production-potential. Afterwards, primary...

Pseudomonas oleovorans NCIMB 6576 and Ralstonia eutropha 10442 were used for the production of Polyhydroxyalkanoates (PHA) from industrial waste cooking oils, bacteria cultured on tryptone soya broth (TSB) Tryptone agar (TSA). P. NCIMB6576 gave a better percentage PHB yield (8.2%) with PS oil as carbon source compared to 6.45% TS oil. However, very low (0.64%) was recorded when grown TSB withou...

BACKGROUND Pseudomonas putida KT2442 is a natural producer of polyhydroxyalkanoates (PHAs), which can substitute petroleum-based non-renewable plastics and form the basis for the production of tailor-made biopolymers. However, despite the substantial body of work on PHA production by P. putida strains, it is not yet clear how the bacterium re-arranges its whole metabolism when it senses the lim...

Given the current plastic disposal global crisis, biodegradable polymers may have an important role in leading way towards a more sustainable industry. Polyhydroxyalkanoates (PHA) are biobased and aliphatic polyesters synthesized by bacteria stored as intracellular granules. In this study, PHA was produced at pilot scale mixed microbial culture (MMC) fed with fermented fruit pulp waste. The acc...

The production of polyhydroxyalkanoates (PHA) using industrial wastewaters as feedstocks is a current and challenging topic. This study investigated the biopolymers by mixed microbial culture under different OLRs equal to 1 kgCOD m?3d?1 (Period 1), 2 2) 3 3). maximum PHA content was achieved in Period (0.38 gPHA gTSS?1), whereas lower values were obtained (0.13 gTSS?1) (0.26 gTSS?1). Overall, p...

Olive tree is a well-known source of polyphenols. We prepared an olive leaf extract (OLE) and characterized it via high performance liquid chromatography (HPLC) analysis. OLE was blended with different polyhydroxyalkanoates (PHAs), namely, poly(hydroxybutyrate-co-hydroxyvalerate) (PHBHV) polyhydroxybutyrate/poly(hydroxyoctanoate-co-hydroxydecanoate) (PHB/PHOHD), to produce fiber meshes electros...
