Production of Polyhydroxyalkanoate by Bacillus thuringiensis Isolated from Agricultural Soils of Cascas-Peru
Summary
Researchers isolated Bacillus thuringiensis SP7-1 from agricultural soils in Cascas, Peru and characterized its production of polyhydroxyalkanoate (PHA) bioplastic, finding 0.54 g/L accumulation representing 19% of dry biomass, with FTIR, DSC, and TGA analysis confirming notable thermal degradation at 270-303 degrees C and a melting temperature of 166.88 degrees C.

Study of Bacterial Biopolymer Production by Bacillus Species
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.
Polyhydroxyalkanoate production from rice straw hydrolysate obtained by alkaline pretreatment and enzymatic hydrolysis using Bacillus strains isolated from decomposing straw
Researchers used rice straw — an agricultural waste product — both as the source for isolating bacteria and as the carbon-rich feedstock to grow them on, successfully producing polyhydroxyalkanoate (PHA), a biodegradable plastic alternative. The best-performing Bacillus bacterial strains converted pretreated rice straw into up to 59% of their body weight as PHA, demonstrating a low-cost pathway for producing compostable bioplastics from farm waste.

Researchers characterized a newly isolated thermotolerant bacterium, Cupriavidus sp. CB15, from composting environments and demonstrated its ability to produce polyhydroxyalkanoate (PHA) bioplastic from glycerol, offering a cost-effective route to biodegradable polymer production.
Insight into polyhydroxyalkanoate (PHA) production from xylose and extracellular PHA degradation by a thermophilic Schlegelella thermodepolymerans
Researchers found that a heat-loving bacterium called Schlegelella thermodepolymerans can convert xylose — a sugar from plant biomass — into up to 80% of its body weight as polyhydroxyalkanoate (PHA), a biodegradable plastic alternative, and can also break down PHA it encounters in the environment.
Bacteria isolated from soil degrade low-density polyethylene for growth and polyhydroxyalkanoate synthesis
Researchers isolated bacteria from plastic waste-contaminated soils and characterised their ability to degrade low-density polyethylene (LDPE), finding that after 16 weeks a bacterial consortium and Chitinophaga oryzae NT1-2 achieved weight losses of 21.97% and 16.14% respectively. FTIR analysis detected new carbonyl functional groups on degraded LDPE surfaces, alkane hydroxylase and alcohol dehydrogenase activities were quantified across strains, and the LDPE-degrading bacteria were also shown to synthesise polyhydroxyalkanoate (PHA), with C. oryzae NT1-2 producing the highest PHA yield of 26.27 mg/g-glucose.
