“…The isolated potential strains could bring >80% decolourization of the reactive dyes (100 mgl -1 ) at static condition within 48 h in a low nutrient medium (Table 2). In connection to the literature, Khalid et al (2008) and Tamboli et al (2010) reported that shaking condition delays the degradation of textile dyes which supports our observation. Similarly, previous reports by Parshetti et al (2011) stated that, the percentage of decolourization was decreased with increasing dye concentration and time required for 100% decolourization of 10, 30, 50, 70 and 100 mgl -1 Crystal Violet by A.…”

The initial selections of bacterial strains were based on effective decolourization of the medium by visible observation and UV-Vis spectral analysis. The operational parameters for dye degradation by the bacterial strains was observed from 6.5 to 7.5 pH range, 35 to 45°C with 100 mg/l dye concentration in static condition for 3 days incubation. The FTIR analysis reveals the modification of the functional groups after bacterial treatment. The reduction of toxicity after bacterial treatment was confirmed using Vigna radiata phytotoxicity study. It was concluded that the native bacterial strains isolated from the sludge environment possess high dye degrading ability. Further characterization of these bacterial strains and their enzymes are necessary for intense field application study.

“…Employment of such bacteria combines bioremediation with the production of a high value-added material. So far, bacterial strains that belong to the genus of Sphingobacterium , Bacillus , Pseudomonas , and Rhodococcus have been isolated and studied regarding their PHA production potential degrading environmental pollutants, as summarized in Table 2 [ 3 , 29 , 33 , 34 , 35 , 36 , 37 , 38 , 39 ].…”

“…In another study, 82% decolorization of 0.8 g/L of the textile dye Orange 3R was feasible, employing Sphingobacterium sp. ATM which resulted in the production of 3.48 g/L of PHD and a cellular PHA content of 65% after 48 h [ 39 ]. In addition, full decolorization of 0.5 g/L of the textile dye Direct Red 5B (DR5B) was accomplished when the medium was supplemented with glycerol, glucose, starch, molasses, frying oil, and cheese whey.…”

Sustainable biofuels, biomaterials, and fine chemicals production is a critical matter that research teams around the globe are focusing on nowadays. Polyhydroxyalkanoates represent one of the biomaterials of the future due to their physicochemical properties, biodegradability, and biocompatibility. Designing efficient and economic bioprocesses, combined with the respective social and environmental benefits, has brought together scientists from different backgrounds highlighting the multidisciplinary character of such a venture. In the current review, challenges and opportunities regarding polyhydroxyalkanoate production are presented and discussed, covering key steps of their overall production process by applying pure and mixed culture biotechnology, from raw bioprocess development to downstream processing.

“…For instance, the harsh reaction conditions and the use of toxic feedstocks, solvents and catalysts are typical disadvantages of these processes. [ 11 ] A possible solution for overcoming these drawbacks is the development of UV‐curable formulations based on biodegradable polymers obtained by a sustainable process, which starts from biomasses or wide types of wastes [ 12–15 ] according to the circular economy framework. [ 16 ] In this view, poly(hydroxyalkanoate)s (PHAs) are the most attractive bacterial polymers, [ 17 ] thanks to their exceptional properties in terms of biodegradability, biocompatibility and bioresorbability.…”

A bio‐based polymeric ink for stereolithography developed through a two‐step solvent‐free process is herein proposed. Specifically, low‐molecular‐weight poly(hydroxybutyrate) (PHB)‐diol oligomers are prepared via molten transesterification of bacterial PHB with 1,4‐butanediol. Transesterification conditions such as diol concentration, catalyst amount, and reaction time are studied for optimizing the final oligomers’ molecular weight and structural features. In the second step, the oligomeric hydroxyl terminals are converted into methacrylate moieties through a solvent‐free end‐capping reaction and diluted in propylene carbonate in order to obtain a photo‐polymerizable ink with suitable viscosity. The ink is UV‐cured, and the obtained material properties are investigated by FT‐IR and differential scanning calorimetry measurements. The proposed method provides a valuable and environmentally friendly alternative to currently available synthetic routes, overcoming their typical disadvantages related to the used solvents and harsh conditions. Moreover, it opens up a sustainable route for converting polyesters into functionalized oligomeric derivatives, which can potentially find application in 3D printing of customized biomedical devices.
