Bioplastic production from bananas by soil isolating bacteria
Main Article Content
Abstract
The research aims to study the bioplastic of polyhydroxyalkanoates (PHAs) production by bacteria isolated from soil samples of Chachoengsao and Nakhon Nayok provinces using 3 kind of ripe banana; Lady Finger, Cavendish and Pisang Awak as carbon sources. Among only 16 isolates can produced PHAs. However, the maximum PHAs content (30.10±0.25%) was obtained from the isolate strain N22-3. The cell morphology was investigated by the Gram staining method using the light microscope. It was found that the N22-3 isolate was a Gram-negative. Then it was identified by 16S rRNA analysis and showed that the PHAs-producing bacterium had maximum sequence 99.85% similarity with Klebsiella pneumoniae. The PHAs film was characterized in its structure. The result showed that it was similar to the standard biopolymer of polyhydroxybutyrate (PHB).
