Pro-ecological packaging materials based on polyhydroxybutyrate (PHB) [PDF]

E3S Web of Conferences, 2018
Polymers are common used in everyday life. For economic reasons and specific properties, they replace traditional materials such as glass, wood or paper. The use of polymeric materials generates waste, whose disposal is difficult. Legislation and pressures on the use of pro-ecological materials have increased interest in biodegradable polymers.

Effects of Carbon‐to‐Nitrogen Ratio in Biofloc System on Water Quality, Growth Performance and Haematological Parameters of Nile Tilapia (Oreochromis niloticus)

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT A 10‐week indoor culture trial was carried out to assess the impact of various C/N ratios on the water quality, growth performance and haematology of Nile tilapia (Oreochromis niloticus) in a biofloc system. The experiment included four biofloc treatment groups with distinct C/N ratios (12:1, 15:1, 18:1 and 21:1) and a control group with a C/N

Influence of reprocessing on monopolymer blends of polyhydroxybutyrate (PHB)

Polymer Testing
This work addresses the mechanical recycling of the biobased and biodegradable polymer Polyhydroxybutyrate (PHB) by investigating different properties at each stage from once extruded (E) PHB blended with virgin (V) material in two ratios (E20V80 and E80V20) and further extruded five times (E5).

Isolation and Enhancement of PHB-producing Bacteria from Sewage using Watermelon Rinds

Journal of Pure and Applied Microbiology
Plastics contribute significantly to global environmental pollution due to their non-biodegradable nature. Biopolymers like polyhydroxybutyrate (PHB), synthesized by microorganisms, offer an eco-friendly alternative.

Design and Statistical Optimization of PLA Organoclay‐Based Dispersions for Recyclable Packaging Paper

Polymer Engineering &Science, Volume 66, Issue 6, Page 4321-4333, June 2026.
Through experimental design, polylactic acid (PLA)—organoclay dispersions were optimized to produce biobased coatings that have a high barrier potential while maintaining repulpability, promoting sustainable packaging solutions. ABSTRACT Performance and recyclability of paper coatings depend on precise control of polymer, surfactant, filler ...

Mechanistic Insight with HBCH₂CoA as a Probe to Polyhydroxybutyrate (PHB) Synthases

ACS Chemical Biology, 2014
Polyhydroxybutyrate (PHB) synthases catalyze the polymerization of 3-(R)-hydroxybutyrate coenzyme A (HBCoA) to produce polyoxoesters of 1-2 MDa. A substrate analogue HBCH2CoA, in which the S in HBCoA is replaced with a CH2 group, was synthesized in 13 steps using a chemoenzymatic approach in a 7.5% overall yield.

Improved polyhydroxybutyrate (PHB) production in transgenic tobacco by enhancing translation efficiency of bacterial PHB biosynthetic genes [PDF]

Journal of Bioscience and Bioengineering, 2011
Polyhydroxybutyrate [P(3HB)] was produced in the transgenic tobacco harboring the genes encoding acetoacetyl-CoA reductase (PhaB) and polyhydroxyalkanoate synthase (PhaC) from Ralstonia eutropha (Cupriavidus necator) with optimized codon usage for expression in tobacco. P(3HB) contents in the transformants (0.2mg/g dry cell weight in average) harboring

Optimization of the phototrophic Cyanobacteria polyhydroxybutyrate (PHB) production by kinetic model simulation

Science of The Total Environment, 2021
Cyanobacteria can grow using inorganic substrates, such as CO2 from industrial sources and nutrients from wastewaters, and therefore are promising microorganisms to produce polyhydroxybutyrate in a cleaner circular context. However, this biotechnological production is highly challenging because it involves different interlinked reactions that are ...

High‐Throughput Screening of Cyanobacterial PHB Production Using Fluorescence‐Based Detection

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
A validated high‐throughput screening protocol using Nile blue fluorescence is presented for optimizing cyanobacterial PHB production. This method enables the simultaneous assessment of multiple environmental parameters in microplates, offering a rapid, low‐volume alternative to gas chromatography to accelerate bioprocess development.
