Functionalisation of polyhydroxybutyrate for diagnostic uses

New Biotechnology
Polyhydroxybutyrate (PHB) is a biodegradable and biocompatible biopolyester, naturally produced and self-assembled as spherical inclusions inside bacteria. These PHB particles contain a hydrophobic PHB core covalently coated with PHB synthase (PhaC), which serves as an anchoring linker for foreign proteins of interest.

Measuring Temporal Variations of Nucleotide Pools in Microbial Granular Biofilm

Helvetica Chimica Acta, Volume 109, Issue 10, October 2026.
The developed metabolomics workflow enables quantification of energy nucleotides in complex microbial biofilms. The method provides a foundation for investigating rapid metabolic responses to dynamic environmental conditions. ABSTRACT Microbial communities often face environmental fluctuations that occur on timescales much shorter than their growth ...

Designing PLA/PHBV Implants With Degradation Matched to Normal or Inflammatory Tissues

Journal of Applied Polymer Science, Volume 143, Issue 36, September 20, 2026.
PLA/PHBV blends are investigated under simulated normal and pathological conditions. Multivariate statistical analysis decouples the competing effects of water‐uptake‐driven hydrolysis and crystallinity‐imposed barriers. Melt‐state rheological parameters serve as structural probes linking phase morphology to degradation kinetics. A semi‐empirical model

Non-growth substrate ethane perturbs core methanotrophy in obligate methanotroph Methylosinus trichosporium OB3b upon nutrient availability

Applied and Environmental Microbiology
Obligate methanotrophs grow exclusively on C1 compounds; however, their widespread ecological distribution and ability to produce polyhydroxybutyrate (PHB) under nutrient stress suggest a greater-than-expected degree of metabolic flexibility.
