Polyhydroxybutyrate (PHB) was the first discovered form of PHA in 1926 and is from Bacillus Megaterium. Today, more than 300 microorganisms are known to synthesis and accumulate PHA intracellularly. Also genetically modified microbes and plants are being reported for the production of PHA. PHA can be of short chain length (3±5 carbon atoms) or medium chain length (6±14 carbon atoms). Polyhydroxyalkanoates are found to be fully biodegradable.
- ItemNovel Non-Thermal Food Processing Technologies for Quality Food Production(Readers Shelf, 2020)Conventional heat treatment methods are generally followed to process the raw agricultural commodities in order to reduce microorganism contamination and to increase the shelf life of the product. These methods can lead to reduction of nutritional quality and sensory properties of the processed foods products. Therefore, to avoid these undesirable changes during the heat treatment and to improve/maintain food quality and safety, novel non-thermal technologies plays very important role in processing of food products.
