Abstract

Plastic waste pollution is escalating globally at an unprecedented pace, with a significant measure of this waste remaining unrecycled. Hence, polyhydroxyalkanoates (PHAs), a biogenic polyester, as a potential alternative to synthetic plastics has been intensively studied over the years. PHAs are biodegradable and biocompatible polyester produced by various microorganisms through the bioprocessing of sustainable sources. Bacterial PHAs show potential as an eco-friendly, biodegradable, and biocompatible alternative to conventional plastics. Malaysian environment, anthropogenic and natural, harbors an enormous diversity of microorganisms as well as various bacteria that produce PHAs. Hence, the current submission highlights on four indigenous PHA producers, isolated from the local environments, namely Cupriavidus malaysiensis USMAA2-4, Cupriavidus malaysiensis USMAA10-20, Cupriavidus malaysiensis USMAHM13, and Pseudomonas putida BET001. The four strains have contributed significantly as a workhorse in advancing PHA research and innovation in Malaysia and globally. Their uniqueness and significance in the PHA investigation, which include biosynthesis, recovery strategies, metabolic pathways involved, characteristics and properties of extracted PHA, biodegradation, and its potential applications are discussed.

从马来西亚环境中分离出的最高短链长度和中链长度的聚羟基烷酸酯微生物生产者

塑料垃圾污染正以前所未有的速度在全球范围内升级，其中很大一部分垃圾仍未回收利用。因此，聚羟基烷酸酯（PHAs）作为一种生物聚酯，作为合成塑料的潜在替代品，近年来得到了广泛的研究。pha是由各种微生物通过可持续来源的生物处理而产生的可生物降解和生物相容性聚酯。细菌pha显示出作为传统塑料的环保、可生物降解和生物相容性替代品的潜力。马来西亚的环境，无论是人为的还是自然的，都孕育着各种各样的微生物以及各种产生pha的细菌。因此，目前提交的重点是从当地环境中分离出的四种本土PHA生产者，即Cupriavidus malaysiensis USMAA2-4， Cupriavidus malaysiensis USMAA10-20， Cupriavidus malaysiensis usmah13和恶臭假单胞菌BET001。这四种菌株作为推动马来西亚和全球PHA研究和创新的主力作出了重大贡献。讨论了它们在PHA研究中的独特性和意义，包括PHA的生物合成、回收策略、代谢途径、提取PHA的特征和性质、生物降解及其潜在应用。图形抽象

期刊介绍： Research papers must make a significant and original contribution to microbiology and be of interest to a broad readership. The results of any experimental approach that meets these objectives are welcome, particularly biochemical, molecular genetic, physiological, and/or physical investigations into microbial cells and their interactions with their environments, including their eukaryotic hosts. Mini-reviews in areas of special topical interest and papers on medical microbiology, ecology and systematics, including description of novel taxa, are also published. Theoretical papers and those that report on the analysis or ''mining'' of data are acceptable in principle if new information, interpretations, or hypotheses emerge.
