Study of Bacterial Biopolymer Production by Bacillus Species
Summary
This study investigated the ability of Bacillus bacteria to produce polyhydroxyalkanoate (PHA) biopolymers, which are biodegradable alternatives to petroleum-based plastics. Microbial biopolymer production could help reduce reliance on conventional plastics that persist and accumulate in the environment.
Modern world can‘t be imagined without plastics due to their vast applications in contemporary life. All the plastic products which are available in market are made up of Petrochemical based synthetic plastics. Such plastics are much difficult to biodegrade which results in its wise accumulation in environment and affects biogeochemical cycles enormously. However, Bioplastics made up of Polyhydroxybutyrate (PHB) provide a better alternative to life threatening petrochemical plastics. PHB is a natural biopolymer produced by numerous bacteria by using different substrates and easy to extract. Thus on nature’s demand the author was performed an experiment with the aim isolate PHB producing bacteria form natural environment and optimized the PHB producing capability of selected isolates. Among twenty two bacterial isolates, five isolates were showed prominent PHB production at 37°C in presence of glucose and sucrose as a carbon source while peptone a nitrogen source in medium with pH 7.0. The isolates which showed more than 50% PHB production were identified as Bacillus licheniformis and Bacillus cereus. PHB polymer production by isolate was confirmed by UV spectrophotometer analysis.

A Review on Biological Synthesis of the Biodegradable Polymers Polyhydroxyalkanoates and the Development of Multiple Applications
This review covers the biological production of polyhydroxyalkanoates, a family of biodegradable bioplastics that bacteria naturally produce from waste carbon sources. Researchers found that these biopolymers have properties similar to conventional plastics like polypropylene but can fully biodegrade, making them a promising alternative to petroleum-based plastics. The study emphasizes that scaling up production and establishing proper end-of-life management are critical steps for PHAs to compete with conventional plastics and help reduce microplastic pollution.
Production of polyhydroxyalkanoate (PHA) biopolymer from crop residue using bacteria as an alternative to plastics: a review
This review examines how PHA, a biodegradable plastic made from crop waste using bacteria, could serve as a sustainable alternative to conventional plastics. While PHA breaks down naturally unlike traditional plastics that fragment into microplastics, challenges remain in making it heat-stable and cost-competitive enough for widespread industrial use.
