On the extraction of cellulose nanowhiskers from food by-products and their comparative reinforcing effect on a polyhydroxybutyrate-co-valerate polymer [PDF]

open access: yes, 2014
The present work reports on the characterization of cellulose nanowhiskers (CNW) extracted from three different food by-products, i.e., wheat straw (WSCNW), Brewers spent grains (BGCNW) and olive pomace (OPCNW), by using an optimized hydrolysis method ...

Natural Antioxidants as Thermal Stabilizers in Fully Biobased PHBV Compounds

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
Polyhydroxyalkanoates (PHA) are promising biobased polymers but degrade easily under heat and oxygen. This study examines PHBV with natural antioxidants to enhance thermal stability during processing. Results show regenerative additives prevent degradation and the effectiveness is comparable to that of synthetic additives.

In vitro biocompatibility assessment of PHBV/Wollastonite composites

open access: yesJournal of Materials Science: Materials in Medicine, 2007
Biodegradable and biocompatible materials are the basis for tissue engineering. As an initial step for developing bone tissue engineering scaffolds, the in vitro biocompatibility of degradable and bioactive composites consisting of polyhydroxybutyrate-co-hydroxyvalerate (PHBV) and wollastonite (W) was studied by culturing osteoblasts on the PHBV/W ...

Coupling Nitrogenous Organic Wastewater Treatment and Biorefinery via N‐Cycling Bacterium

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
The vast reservoir of nitrogenous organic pollutants in industrial wastewaters can serve as untapped carbon‐nitrogen resources. This study employs the newly discovered Paracoccus sp. ZQW‐1 as a versatile chassis to simultaneously achieve N‐methylpyrrolidone (NMP) wastewater depuration and polyhydroxybutyrate (PHB) synthesis.

Aligned bacterial PHBV nanofibrous conduit for peripheral nerve regeneration

open access: yesArtificial Cells, Nanomedicine, and Biotechnology, 2014
The conventional method of peripheral nerve gap treatment is autografting. This method is limited. In this study, an aligned nanofibrous graft was formed using microbial polyester, Poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV). The regenerative effect of the graft was compared with that of autografting in vivo.

Bionanocomposites based on 3-hydroxybutyrate-co-3-hydroxyvalerate (PHBV) and cellulose nanowhiskers (CNWs) [PDF]

open access: yes, 2016
Over the past decade, bio-based polymers, especially in packaging, have gained a bigger role due to the over consuming of petrol derivates and the gradually growing concerns relating environment and sustainability issues.
