3‐hydroxybutyrate in the brain: Biosynthesis, function, and disease therapy

Brain-X, 2023
3‐hydroxybutyrate (3HB), or BHB, is an anionic small molecule acid metabolite with a hydroxyl group. 3HB is the major ketone body that is distributed in the human brain and its primary energy source when glucose is absent.

Can Biomass Mastication Assist the Downstreaming of Polyhydroxyalkanoates Produced from Mixed Microbial Cultures?

Molecules, 2023
Polyhydroxyalkanoates (PHAs) are natural polyesters which biodegrade in soils and oceans but have more than double the cost of comparable oil-based polymers. PHA downstreaming from its biomass represents 50% of its overall cost.

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.
