“…This method remains economical, as it uses only 3.5 g/L of carbon substrates for the production of PHBV with high, 80%, 3-HV content comparing to previously reported studies, with 20 g/L of inducing substrates [25,37]. Finally, to go forward and circumvent the inhibition effect observed here, an application of continuous strategy may be worthwhile, indeed, this technique has been previously described as valuable for such type of improvements [15,38,39]. Time courses for CDM (a), and substrates concentration in the medium (b), during the scale-up experiment.…”

“…The production of PHB can be achieved by many strains and at relevant yields and production rates [9][10][11]. These polymers can be used either for technical [12], medical [13] or bioremediation [14,15] purposes. However, certain applications require less brittle, more elastic polymer with lower glass transition temperature (T g ).…”

In the context of increasing volatility of oil prices, replacement of petroleum based plastics by bioplastics is a topic of increasing interest. Poly(hydroxyalkanoate)s (PHAs) are among the most promising families in this field. Controlling composition of the polymer on the monomeric level remains a pivotal issue. This control is even more difficult to achieve when the polymer is not synthesized by chemists, but produced by nature, in this case, bacteria. In this study mechanism and role of two 3-hydroxyvalerate (3-HV) inducing substrates on the production of PHBV with high, 80%, 3-HV content were evaluated. It was found that levulinic acid contributes to biomass and bio-polymer content enhancement, whereas sodium propionate mainly contributes to 3-HV enhancement. Optimized proportions of feeding substrates at 1 g/L and 2.5 g/L, respectively for levulinic acid and sodium propionate allowed a 100% productivity enhancement, at 3.9 mg/L/hour, for the production of PHBV with 80% 3-HV.

“…Berezina et al (2015) reported that benzoic acid was found to be a crucial compound for the bioremediation by Cupriavidus necator, and this strain transforms benzoic acid to the PHB showed that this bioremediation process is more suitable for the purification of waste streams. Koller and Braunegg (2015) reported PHB and poly(3-hy droxybutyrate-co-3-hydroxyvalerate) (PHBV) production by C. necator strain DSM 545 using animal-based crude glycerol phase (CGP) and the saturated biodiesel share (SFAE).…”

In the present study five different types of alkylphenols, each of the two different types of mono and poly-aromatic hydrocarbons were selected for degradation, and conversion into poly-3-hydroxybutyrate (PHB) using the Bacillus sp. CYR1. Strain CYR1 showed growth with various toxic organic compounds. Degradation pattern of all the organic compounds at 100 mg/l concentration with or without addition of tween-80 were analyzed using high pressure liquid chromatography (HPLC). Strain CYR1 showed good removal of compounds in the presence of tween-80 within 3 days, but it took 6 days without addition of tween-80. Strain CYR1 showed highest PHB production with phenol (51 ± 5%), naphthalene (42 ± 4%), 4-chlorophenol (32 ± 3%) and 4-nonylphenol (29 ± 3%). The functional groups, structure, and thermal properties of the produced PHB were analyzed. These results denoted that the strain Bacillus sp. CYR1 can be used for conversion of different toxic compounds persistent in wastewaters into useable biological polyesters.
