“…In our previous work, with a mesophilic laccase it was found that, the deactivation energy (E d ) of NP-laccase as calculated from the Arrhenius plot was around 6.768 kJ/mol while that for the laccase (ÀNP) was À47.532 kJ/mol. For the NP-laccase from E. coli the halflife of inactivation was 60 min at 40°C as compared to 330 min at 80°C (Mukhopadhyay et al, 2013b). In our study, taken with the earlier report, it was found that there was a commonality vis a vis imparting thermostability to both mesophilic and psychrophilic enzymes by treatment with the corresponding nanoparticle (cofactor).…”

“…Afterwards, the presence of galacturonic acid and reducing sugars, which are residues of gummy substances, can indicate the degumming extent474849. Both galacturonic acid and reducing sugars were maintained at higher concentrations in the BA samples than in the CK samples throughout the entire retting period (Fig.…”

High-throughput sequencing and GC-MS (gas chromatography-mass spectrometry) were jointly used to reveal the bacterial succession and metabolite changes during flax (Linum usitatissimum L.) retting. The inoculation of Bacillus cereus HDYM-02 decreased bacterial richness and diversity. This inoculum led to the replacement of Enterobacteriaceae by Bacillaceae. The level of aerobic Pseudomonadaceae (mainly Azotobacter) and anaerobic Clostridiaceae_1 gradually increased and decreased, respectively. Following the addition of B. cereus HDYM-02, the dominant groups were all degumming enzyme producers or have been proven to be involved in microbial retting throughout the entire retting period. These results could be verified by the metabolite changes, either degumming enzymes or their catalytic products galacturonic acid and reducing sugars. The GC-MS data showed a clear separation between flax retting with and without B. cereus HDYM-02, particularly within the first 72 h. These findings reveal the important bacterial groups that are involved in fiber retting and will facilitate improvements in the retting process.

“…A reducing sugar was also produced using Bacillus megaterium AK2 with BP as the substrate that was treated with hydroxyapatite nanoparticles supplemented by pure pectate lyase. This has ability to enhance fiber tenacity and degum and decorticate ramie fibers, which have applications in bioethanol, biofuel, and textile industries (Mukhopadhyay et al 2013).…”

AbstractBanana peel (BP) is an agrowaste produced in large volumes annually, especially by food-processing industries; however, its disposal is of significant concern. However, recent research suggests that BP is a valuable source of bioactive compounds, which can be converted into value-added products. This article reviews the conversion process of value-added products from BP and provides an outline on the chemical composition of BP and its possible applications. In addition, we also discuss the utilization of BP as a substrate to produce animal feed, biofertilizer, dietary fibers, clean energy, industrial enzymes, as well as its use in the synthesis of nanomaterials. Based on the research conducted so far, it is obvious that BP has a wide variety of applications, and thus, developing a biorefinery approach to adequately utilize BP will help realize its economic benefits to the fullest. Based on the valorization of BP, a scheme for BP biorefinery has been proposed. A material balance for BP biorefinery for 1-ton bone-dry BP is presented and our results show that 432 kg of protein or 170 kg of citric acid, 170 kg of pectin, 325 m
