Beyond PEG: Emerging Polymer Lipid Alternatives for Lipid Nanoparticle (LNP) Formulations

Advanced Science, EarlyView.
This review discusses recent advances in PEG‐alternative LNP designs, including non‐PEG polymers, zwitterionic lipids, and polypeptides. It evaluates how surface‐engineering chemistry influences LNP formation and biological behavior, and highlights current limitations and opportunities of PEG‐alternative LNPs.

Biodegradation Behavior of Polyhydroxyalkanoates on the Territory of Vietnam and Central Siberia [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2012
For the first time, PHA biodegradation was studied in microecosystems situated in different regions and under different climate conditions. The study showed that the time necessary for the polymer weight to decrease to a half of its initial weight, could

Production of Polyhydroxyalkanoates Using Hydrolyzates of Spruce Sawdust: Comparison of Hydrolyzates Detoxification by Application of Overliming, Active Carbon, and Lignite

Bioengineering, 2017
Polyhydroxyalkanoates (PHAs) are bacterial polyesters which are considered biodegradable alternatives to petrochemical plastics. PHAs have a wide range of potential applications, however, the production cost of this bioplastic is several times higher.

Application of Immersed Membrane Bioreactor for Semi-Continuous Production of Polyhydroxyalkanoates from Organic Waste-Based Volatile Fatty Acids

Membranes, 2023
Volatile fatty acids (VFAs) appear to be an economical carbon feedstock for the cost-effective production of polyhydroxyalkanoates (PHAs). The use of VFAs, however, could impose a drawback of substrate inhibition at high concentrations, resulting in low ...

Biomedical Applications of Polyhydroxyalkanoates [PDF]

Indian Journal of Microbiology, 2017
Polyhydroxyalkanoates (PHA) are produced by a large number of microbes under stress conditions such as high carbon (C) availability and limitations of nutrients such as nitrogen, potassium, phosphorus, magnesium, and oxygen. Here, microbes store C as granules of PHAs-energy reservoir.

Sustainable Manufacturing Platforms for Closed‐Cycle Bioeconomy Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The transition to a circular bioeconomy requires innovative production platforms that prioritize sustainability, resource efficiency, and waste minimization. Organic waste from agriculture, aquaculture, and food production represents an underutilized feedstock for biomanufacturing, contributing to a circular economy.
