Get PDFSerratia peptidase is active proteolytic enzyme which has the potential of cleaving peptide bond. Present investigation deals about the Microbial production of serratia peptidase using Serratia marcescens in small scale fermentor. Batch fermentor has been run continuously throughout the night to analyze the production of protein as well as kinetics. Culture broth was maintained at 150rpm for 72 hrs. Protein sample was isolated by centrifuging at 3000rpm for 10mints. The result revealed that Serratia marcescens showed the enormous production of protein in fed batch fermentor compared to the small scale level. Different substrates were been used for the production of enzyme. Among all cysteine showed the better activity as 2 units/ml of enzyme. Enzymatic assay of Serratia peptidase was done at different time interval of crude broth. Enzyme activity showed that maximum at 40ºC for 72hrs. It was observed that 0.65 units/ml of enzyme. Fed batch pilot scale production of Serratia peptidase was done at 0.5%cystein and 700rpm for 48hrs of run time.Â
Removal of nanoplastics in water treatment processes: a review
No full textNanoplastics are drawing a significant attention as a result of their propensity to spread across the environment and pose a threat to all organisms. The presence of nanoplastics in water is given attention nowadays as the transit of nanoplastics occurs through the aquatic ecosphere besides terrestrial mobility. The principal removal procedures for macro-and micro-plastic particles are effective, but nanoparticles escape from the treatment, increasing in the water and significantly influencing the society. This critical review is aimed to bestow the removal technologies of nanoplastics from aquatic ecosystems, with a focus on the treatment of freshwater, drinking water, and wastewater, as well as the importance of transit and its impact on health concerns.
Still, there exists a gap in providing a collective knowledge on the methods available for nanoplastics removal. Hence, this review offered various nanoplastic removal technologies (microorganism-based degradation, membrane separation with a reactor, and photocatalysis) that could be the practical/effective measures along with the traditional procedures (filtration, coagulation, centrifugation, flocculation, and gravity settling). From the analyses of different treatment systems, the effectiveness of nanoplastics removal depends on various factors, source, size, and type of nanoplastics apart from the treatment method adopted. Combined removal methods, filtration with coagulation offer great scope for the removal of nanoplastics from drinking water with >99 % efficiency. The collected data could serve as base-line information for future research and development in water nanoplastics cleanup
