Efficiency of Polyhydroxyalkanoate (PHAs) Production from Palm Oil using Pseudomonas aeruginosa BSE1(OP474060)

Abstract

This study focuses on the efficiency of Polyhydroxyalkanoate (PHAs) production from palm oil using Pseudomonas aeruginosa BSE1(OP474060). It was found that the influence of palm oil concentration on the growth and PHAs accumulation of P. aeruginosa BSE1 showed that palm oil concentration affected the growth and PHAs accumulation. At concentrations of 0.50 and 0.75%w/v, the maximum dry cell weights were 3.83 and 4.83 g L -1 respectively. The study of PHAs yield and structural analysis by FTIR technique showed that palm oil concentration of 0.75 % w/v had the highest PHAs yield of 40.83 %. This concentration is suitable for the production and accumulation of PHAs. The results of the structural analysis of the extracted PHAs using the FTIR technique revealed methyl and methylene groups in the range of 2,900-2,800 cm−1 which is the specific position of medium-chain PHAs (mcl-PHA) found from P. aeruginosa BSE1. Further research should focus on the economic feasibility of PHAs production from palm oil. Finally, this research can support the palm oil industry and stimulate demand for bioplastics, thereby facilitating adaptation to climate change.
