Recycled Cellulose‐Based Colorimetric Indicators for Non‐Contact Detection of Food Contamination

Advanced Sustainable Systems, Volume 10, Issue 4, April 2026.
Recycled cellulose acetate films, functionalized with red cabbage anthocyanins, combine antioxidant activity and pH‐responsive color changes for smart food packaging. They extend shelf life by preventing oxidation and enable non‐contact detection of bacterial contamination via VOC‐triggered color shifts.

The Optimization Conditions of Polyhydroxybutyrate Methyl Ester from Polyhydroxybutyrate via Acid-Catalyst

Energy Procedia, 2017
Abstract Recently, microbial polyhydroxyalkanoates (PHA) were proposed as an alternative biofuel, termed 3-hydroxyalkanoate methyl ester (3HAME). PHA is a strong candidate to make biofuels and be used in the fuel additive market today. However, an optimization study of 3HAME from PHA has never been reported.

Polyhydroxybutyrate production by freshwater SAR11 (LD12)

The ISME Journal
Abstract SAR11 bacteria (order Pelagibacterales) are oligotrophs and often the most abundant bacterioplankton in aquatic environments. A subset of sequenced SAR11 genomes, predominantly in the brackish and freshwater SAR11 subclades, contain homologs of pha genes, which in other organisms confer the ability to store carbon and energy via

Electrospun Pectin-Polyhydroxybutyrate Nanofibers for Retinal Tissue Engineering [PDF]

, 2017
Natural polysaccharide pectin has for the first time been grafted with polyhydroxybutyrate (PHB) via ring-opening polymerization of β-butyrolactone. This copolymer, pectin-polyhydroxybutyrate (pec-PHB), was blended with PHB in various proportions and ...
