“…With respect to PHA production from grape pomace extract, T. taiwanensis can be considered being very promising bacterium. In a similar study, Kovalcik et al obtained comparable or lower PHB titers employing Halomonas halophila (1.8 g/L of PHB), Halomonas organivorans (2.1 g/L of PHB) and Cupriavidus necator (1.9 g/L PHB) [35]. Nevertheless, T. taiwanesis provides all the above-mentioned advantages associated with the cultivation of thermophilic bacterium.…”

“…Using 20 g/L of grape sugar extract in the flask test, the cell dry mass of Cupriavidus necator H16 reached 4 g/L, and PHA production was almost 2 g/L. Furthermore, PHA production using halophilic strains produced comparable results of 1.8 g/l for Halomonas halophila, and the highest production was recorded in Halomonas organivorans 2.1 g/L [35]. Extremophiles may be a suitable alternative to mesophiles regarding PHA production.…”

“…Grape pomace has several uses; it can be used as a food supplement [30], fertilizer [31], or feed [32][33][34]. However, it can also be used as a carbon waste source for biotechnology purposes [35,36]. Therefore, this material can be a suitable resource to produce PHA.…”

Polyhydroxyalkanoates (PHA) are microbial polyesters that have recently come to the forefront of interest due to their biodegradability and production from renewable sources. A potential increase in competitiveness of PHA production process comes with a combination of the use of thermophilic bacteria with the mutual use of waste substrates. In this work, the thermophilic bacterium Tepidimonas taiwanensis LMG 22826 was identified as a promising PHA producer. The ability to produce PHA in T. taiwanensis was studied both on genotype and phenotype levels. The gene encoding the Class I PHA synthase, a crucial enzyme in PHA synthesis, was detected both by genome database search and by PCR. The microbial culture of T. taiwanensis was capable of efficient utilization of glucose and fructose. When cultivated on glucose as the only carbon source at 50°C, the PHA titers reached up to 3.55 g/L, and PHA content in cell dry mass was 65%. The preference of fructose and glucose opens the possibility to employ T. taiwanensis for PHA production on various food wastes rich in these abundant sugars. In this work, PHA production on grape pomace extracts was successfully tested.

“…In particular, they used dephenolized grape pomace to produce volatile fatty acids (VFAs) by anaerobic acidogenic digestion and they exploited these VFAs as carbon substrate for the production of mcl-PHAs. Kovalcic et al [ 128 ] used oils and fermentable sugars derived from grape pomace as carbon nutrient for Cupriavidus necator to produce PHB in a 2-L reactor, obtaining a volumetric PHB productivity of 1.363 g/Lh. Moreover, in addition to fermentable sugars and lipids, authors also isolated pigments, phenolic compounds, lignin, and cellulose from the same wine peels and seeds, proposing a circular system of bio-refinery.…”

The plastic industry is today facing a green revolution; however, biopolymers, produced in low amounts, expensive, and food competitive do not represent an efficient solution. The use of wine waste as second-generation feedstock for the synthesis of polymer building blocks or as reinforcing fillers could represent a solution to reduce biopolymer costs and to boost the biopolymer presence in the market. The present critical review reports the state of the art of the scientific studies concerning the use of wine by-products as substrate for the synthesis of polymer building blocks and as reinforcing fillers for polymers. The review has been mainly focused on the most used bio-based and biodegradable polymers present in the market (i.e., poly(lactic acid), poly(butylene succinate), and poly(hydroxyalkanoates)). The results present in the literature have been reviewed and elaborated in order to suggest new possibilities of development based on the chemical and physical characteristics of wine by-products.

“…So far, only a few papers described the use of grape pomace as a carbon source for the biosynthesis of PHAs. Kovalcik et al [ 78 ] compared the potential of Cupriavidus necator , Halomonas halophila and Halomonas organivorans to produce P(3HB) by using oil and fermentable sugars derived from grape pomace. However, Cupriavidus necator was found to be the best producer that after 29.5 h of the biofermentation was able to produce 8.5 g L −1 of P(3HB) corresponding to 63% of CDW.…”

The rising global consumption and industrialization has resulted in increased food processing demand. Food industry generates a tremendous amount of waste which causes serious environmental issues. These problems have forced us to create strategies that will help to reduce the volume of waste and the contamination to the environment. Waste from food industries has great potential as substrates for value-added bioproducts. Among them, polyhydroxyalkanaotes (PHAs) have received considerable attention in recent years due to their comparable characteristics to common plastics. These biodegradable polyesters are produced by microorganisms during fermentation processes utilizing various carbon sources. Scale-up of PHA production is limited due to the cost of the carbon source metabolized by the microorganisms. Therefore, there is a growing need for the development of novel microbial processes using inexpensive carbon sources. Such substrates could be waste generated by the food industry and food service. The use of industrial waste streams for PHAs biosynthesis could transform PHA production into cheaper and more environmentally friendly bioprocess. This review collates in detail recent developments in the biosynthesis of various types of PHAs produced using waste derived from agrofood industries. Challenges associated with this production bioprocess were described, and new ways to overcome them were proposed.
