Polyhydroxyalkanoates (PHA) are biodegradable plastic. Numerous bacteria produce PHAs under environmental stress conditions, such as excess carbon-rich organic matter and limitations of other nutritional elements potassium, magnesium, oxygen, phosphorus, nitrogen. In addition to having physicochemical properties similar fossil-fuel-based plastics, have unique features that make them ideal for medical devices, easy sterilization without damaging the material itself dissolution following use. can replace traditional plastic materials used in biomedical sector. be a variety applications, including implants, drug delivery wound dressings, artificial ligaments tendons, bone grafts. Unlike not manufactured from petroleum products or fossil fuels are, therefore, environment-friendly. this review, recent overview applications with special emphasis on sectors, delivery, healing, tissue engineering, biocontrols, discussed.

Carboxylic acids have become interesting platform molecules in the last years due to their versatility act as carbon sources for different microorganisms or precursors chemical industry. Among carboxylic acids, short-chain fatty (SCFAs) such acetic, propionic, butyric, valeric, and caproic can be biotechnologically produced an anaerobic fermentation process from lignocellulose other organic wastes of agricultural, industrial, municipal origin. The biosynthesis SCFAs is advantageous compared synthesis, since latter relies on fossil-derived raw materials, expensive toxic catalysts harsh conditions. This review article gives overview complex waste products. Different applications are explored how these considered a source bioproducts, aiming at development circular economy. use requires adequate concentration separation processes that also addressed this review. Various bacteria oleaginous yeasts efficiently SCFA mixtures derived fermentation, attribute exploited microbial electrolytic cells produce biopolymers oils polyhydroxyalkanoates. Promising technologies conversion into bioproducts outlined with recent examples, highlighting future bioeconomy.

Abstract Background Plastic is widely utilized in packaging, frameworks, and as coverings material. Its overconsumption slow degradation, pose threats to ecosystems due its toxic effects. While polyhydroxyalkanoates (PHA) offer a sustainable alternative petroleum-based plastics, their production costs present significant obstacles global adoption. On the other side, multitude of household industrial activities generate substantial volumes wastewater containing both organic inorganic contaminants. This not only poses threat but also presents opportunities get benefits from circular economy. Main body abstract Production bioplastics may be improved by using nutrients minerals feedstock for microbial fermentation. Strategies like feast-famine culture, mixed-consortia integrated processes have been developed PHA highly polluted with high loads. Various process parameters loading rate, content (volatile fatty acids), dissolved oxygen, operating pH, temperature critical roles accumulation biomass. Research advances are going on downstream recovery utilizing combination physical chemical (halogenated solvents, surfactants, green solvents) methods. review highlights recent developments upcycling resources into PHA, encompassing various strategies, processing methodologies, techno-economic analyses. Short conclusion Organic carbon nitrogen promising, cost-effective source producing bioplastic. Previous attempts focused enhancing productivity through optimizing culture systems growth conditions. However, despite technological progress, challenges persist, such low productivity, intricate processing, scalability issues, properties resulting PHA. Graphical

Currently, the global demand for polyhydroxyalkanoates (PHAs) is significantly increasing. PHAs are produced by several bacteria that an alternative source of synthetic polymers derived from petrochemical refineries. This study established a simple and more feasible process PHA production Halomonas alkaliantarctica using dairy waste as only carbon source. The data confirmed analyzed halophile could metabolize cheese whey (CW) mother liquor (CWML) into biopolyesters. highest yield was 0.42 g/L in cultivation supplemented with CWML. Furthermore, it proved structure depended on type by-product manufacturing, its concentration, culture time. results revealed H. produce P(3HB-co-3HV) copolymer cultivations CW at 48 h 72 without adding any precursors. Based obtained physicochemical thermal analyses, extracted reported to have properties suitable various applications. Overall, this described promising approach valorizing future strategy industrial management high value microbial biopolymers.

Polyhydroxyalkanoates (PHA) are biodegradable biopolymers produced by prokaryotic microbes, which, at the same time, can be applied as single-cell proteins (SCPs), growing on renewable waste-derived substrates. These PHA polymers have gained increasing attention a sustainable alternative to conventional plastics. One promising application of and PHA-rich SCPs lies within aquaculture food industry, where they hold potential feed additives, biocontrol agents against diseases, immunostimulants. Nevertheless, cost production remains high, partly due expensive substrates for cultivating PHA-accumulating SCPs, costly sterilization, energy-intensive harvesting techniques, toxic extraction purification processes. This review summarizes current state its in aquaculture. The structure classification PHA, microbial sources, cultivation substrates, biosynthesis pathways, challenges solutions discussed. Next, is explored, focusing challenges, common innovative PHA-integrated farming practices, mechanisms inhibiting pathogens, enhancing immune system, improving growth gut health various aquatic species. Finally, future research needs identified. Overall, this paper provides comprehensive overview highlights need further area.
