Summary of "Production of polyhydroxyalkanoates by halotolerant bacteria with volatile fatty acids from food waste as carbon source."

In this study, a halotolerant strain was isolated from high salinity leachate and identified as Bacillus cereus NT-3. It can produce high concentration of polyhydroxyalkanoates (PHAs) with no significant changes when NaCl concentration is up to 50 g/L. FTIR and NMR spectra of PHAs synthesized by Bacillus cereus NT-3 were similar to the standard or previous results. Effluent from acidogenic fermentation of food waste and pure volatile fatty acids (VFAs) mixture was used as carbon source to check the effect of non-VFAs compounds of the effluent on PHAs production. The maximum PHAs production was 0.42 g/L for effluent fermentation, while it was 0.34 g/L for pure VFAs fermentation, indicating that bacteria could use actual effluent in better way. Furthermore, a mathematical model was established for describing kinetic behavior of bacteria using different carbon source. These results provided a promising approach for PHAs biosynthesis with low-cost carbon source. This article is protected by copyright. All rights reserved.

Medical and Biotech [MESH] Definitions

Short-chain fatty acids of up to six carbon atoms in length. They are the major end products of microbial fermentation in the ruminant digestive tract and have also been implicated in the causation of neurological diseases in humans.

FATTY ACIDS found in the plasma that are complexed with SERUM ALBUMIN for transport. These fatty acids are not in glycerol ester form.

Organic, monobasic acids derived from hydrocarbons by the equivalent of oxidation of a methyl group to an alcohol, aldehyde, and then acid. Fatty acids are saturated and unsaturated (FATTY ACIDS, UNSATURATED). (Grant & Hackh's Chemical Dictionary, 5th ed)

UNSATURATED FATTY ACIDS that contain at least one double bond in the trans configuration, which results in a greater bond angle than the cis configuration. This results in a more extended fatty acid chain similar to SATURATED FATTY ACIDS, with closer packing and reduced fluidity. HYDROGENATION of unsaturated fatty acids increases the trans content.

Fatty acid biopolymers that are biosynthesized by microbial polyhydroxyalkanoate synthase enzymes. They are being investigated for use as biodegradable polyesters.
