Characterization of Polyhydroxybutyrate Nanoparticles

Iraqi Journal of Science, 2022
     Preparation of nanoparticles is one of the important ways to increase the biological effectiveness of materials. There are several methods to prepare the polyhydroxybutyrate (PHB) nanoparticles. Here, a new method is used based on exposing PHB to ultrasound waves under variable pH conditions.

In vivo and Post-synthesis Strategies to Enhance the Properties of PHB-Based Materials: A Review

Frontiers in Bioengineering and Biotechnology, 2021
The transition toward “green” alternatives to petroleum-based plastics is driven by the need for “drop-in” replacement materials able to combine characteristics of existing plastics with biodegradability and renewability features.

Effective and Sustained Control of Soil-Borne Plant Diseases by Biodegradable Polyhydroxybutyrate Mulch Films Embedded with Fungicide of Prothioconazole

Molecules, 2021
Soil-borne diseases and plant rhizosphere nematode have caused many crop yield losses. Increased environmental awareness is leading to more restrictions on the use of certain fumigants and root irrigation methods due to their impact on human health and ...

Polyhydroxybutyrate: An intriguing biopolymer

Bioscience Reports, 1988
The microbial polymer poly-3-hydroxybutyrate (PHB) and related poly-hydroxyalkanoates, such as poly-3-hydroxyvalerate and poly-3-hydroxyoctanoate, are unique biodegradable thermoplastics of considerable commercial importance. The structure, properties and regulation of synthesis and degradation of PHB are reviewed and the microbial production of ...

Polyhydroxybutyrate accumulation by a Serratia sp.

Biotechnology Letters, 2007
A strain of Serratia sp. showed intracellular electron-transparent inclusion bodies when incubated in the presence of citrate and glycerol 2-phosphate without nitrogen source following pre-growth under carbon-limitation in continuous culture. About 1.3 mmol citrate were consumed per 450 mg biomass, giving a calculated yield of maximally 55% of stored ...

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

Journal of Applied Polymer Science, EarlyView.
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

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial
