Polyhydroxyalkanoate as Next Generation Bioplastics for Sustainability and Circular Energy Management

open access: yesEcoMat, Volume 8, Issue 9, September 2026.
Circular system converting wastewater sludge (WWS) into PHA bioplastics via acidification and MMC biosynthesis. System highlights LCA framework, showing GWP trade‐offs against fossil plastics and costs of $3–5/kg PHA, ultimately achieving lower carbon footprints and resource recovery for a sustainable bioeconomy.

Lymphocyte Micronucleus Formation Is Driven by Inflammation‐Induced Oxidative DNA Damage in Oesophageal Cancer Development

open access: yesInternational Journal of Cancer, Volume 159, Issue 5, Page 1311-1321, 1 September 2026.
Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...

Studies on polyhydroxyalkanoate (PHA) accumulation in a PHA synthase I-negative mutant ofBurkholderia cepaciagenerated by homogenotization [PDF]

open access: yesFEMS Microbiology Letters, 2000
In the genome of Burkholderia cepacia strain IPT64, which accumulates a blend of the two homopolyesters poly(3-hydroxybutyrate), poly(3HB), and poly(3-hydroxy-4-pentenoic acid), poly(3H4PE), from sucrose or gluconate as single carbon source, the polyhydroxyalkanoate (PHA) synthase structural gene was disrupted by the insertion of a chloramphenicol ...

PhaC Synthases and PHA Depolymerases: The Enzymes that Produce and Degrade Plastic

open access: yesInternational Islamic University Malaysia Engineering Journal, 2011
PHAs are a group of intracellular biodegradable polymer produced by (most) bacteria under unbalanced growth conditions. A series of enzymes are involved in different PHAs synthesis, however PhaC synthases are responsible for the polymerization step. PHAs

Heterologous expression of lipase gene (lip) and PHA synthase gene (PHAC1) from pseudomonas spp. in escherichia coli for the biosynthesis of polyhydroxyalkanoates (PHA) / Aung Shuh Wen [PDF]

open access: yes, 2011
Polyhydroxyalkanoates (PHA) are natural biodegradable and biocompatible plastic materials which potentially have a wide range of applications. The potential commercial value of these polyesters prompts a demand for intensive studies to maximise their ...
