“…85 Previous reports have documented K. pneumoniae isolates as being capable of producing PHA in a range from 0.13 to 9.6 g L −1 . [85][86][87] Notably, strain E22 was able to produce at least 2.5 times more biopolymers than previously obtained with bacterial isolates of the same species, indicating a promising production capacity under the evaluated conditions. 88 This study reported the production of 88.58 ± 1.07 g L −1 of biomass, which had 26.40 ± 4.65% of P3HB, from a culture medium containing just 12.18 ± 5.31 g L −1 of carbohydrates and 1.62 ± 0.23 g L −1 of protein.…”

“…Decreasing the rate of acetyl-CoA admission into tricarboxylic acid generates greater targeting to PHA biosynthesis pathways, consequently increasing PHA production. 83 In some works, the production of PHA was evaluated using simple orange peel extracts (Sukan et 68,84,85 Sukan, Roy and Keshavarz performed cultures of Bacillus subtilis OK2 in a medium containing microwave-pretreated orange peel solutions, acid or water suspension in the presence of glucose and citrate. 68 The highest content of P3HB was obtained with orange peel suspensions in water.…”

Polyhydroxyalkanoates (PHA) are naturally occurring polyesters accumulated by bacteria under conditions of inorganic nutrient limitations and excess carbon. They offer renewable and biodegradable alternatives to petroleum‐based polymers, especially those used in transient single‐use applications. However, PHA still faces high production costs, primarily linked to the carbon source, lower productivity in processes and an early stage of technical development in comparison with well‐established fossil‐based polymers, which challenge its transition to a true commodity market. Recent research has highlighted the potential of renewable, inexpensive, abundant and non‐edible carbon‐rich residues from agriculture, municipal solid waste and industrial byproducts as alternative carbon sources in developing the production process. Recognizing Brazil's position as the leading producer of both citrus and sugarcane, this review introduces a novel citrus–sugarcane biorefinery model for PHA production, capitalizing on the geographical and operational synergies of both sectors. The proposed model integrates wet citrus pulp as a second‐generation carbon source, sugarcane industry fermenters, waste management, solvents and renewable energy from both sectors. Primary challenges involve the need for efficient, low‐cost biomass pre‐treatment to remove limonene and partially extract citric pectin, coupled with the partial hydrolysis of pectin to enhance solubility and reduce viscosity. Additional considerations include determining citrus biomass composition and sugar consumption, screening bacterial diversity for optimal PHA production, and deepening our understanding of the metabolic pathways underpinning the catabolism of citrus residues. Future research should focus on enhancing PHA concentrations and diversity and finally conducting life cycle assessment studies to evaluate the sustainability and feasibility of this proposed model.

“…To make the production of PHA competitive, it is necessary to use low-value waste materials as a substrate [ 159 ]. Different waste streams have been evaluated ( Table 2 ), such as waste vegetable oil [ 160 , 161 ] and fruit waste [ 159 , 162 , 163 ].…”

Plastics have become an essential part of the modern world thanks to their appealing physical and chemical properties as well as their low production cost. The most common type of polymers used for plastic account for 90% of the total production and are made from petroleum-based nonrenewable resources. Concerns over the sustainability of the current production model and the environmental implications of traditional plastics have fueled the demand for greener formulations and alternatives. In the last decade, new plastics manufactured from renewable sources and biological processes have emerged from research and have been established as a commercially viable solution with less adverse effects. Nevertheless, economic and legislative challenges for biobased plastics hinder their widespread implementation. This review summarizes the history of plastics over the last century, including the most relevant bioplastics and production methods, the environmental impact and mitigation of the adverse effects of conventional and emerging plastics, and the regulatory landscape that renewable and recyclable bioplastics face to reach a sustainable future.

“…As fruit waste extract provides good nutrition for biochemical production, it has been utilized for melanin production. Tarangini and Mishra reported that Bacillus safensis , isolated from garden soil, could produce 6.96 g/L of melanin within 10 h of incubation ( Tarangini and Mishra, 2014 ; Valdez-Calderón et al, 2020 ).…”

Melanin is one of the most abundant pigments found in the biosphere. Owing to its high biocompatibility and diverse biological activities, it has been widely applied as a functional biomaterial in the cosmetic, pharmaceutical, biopolymer, and environmental fields. In this study, the production of melanin was comprehensively reviewed concerning bioconversion and isolation processes. First, several melanogenic microbes, including fungi and bacteria, were summarized. Melanin production was classified by host and melanin type and was analyzed by titers in g/L in addition to reaction conditions, including pH and temperature. The production was further interpreted using a space-time yields chart, which showed two distinct classifications in productivity, and reaction conditions were analyzed using a pH-temperature-titer chart. Next, the extraction process was summarized by crude and pure melanin preparation procedures, and the extraction yields were highlighted. Finally, the recent applications of melanin were briefly summarized, and prospects for further application and development in industrial applications were suggested.
