Bio-plastic is a 19 production from anaerobic codigestion of natural polymeric material that has been developed extensively over croton bonplindianus baill the last two decades due to its good biocompatibility, biodegradability, and material properties. Mosquito repellent textiles are one of the revolutionary ways to Production of bio-plastics for food storage and 20 advance the textile field by providing the much-needed features of analysis of its properties driving away mosquitoes, especially in the tropical areas. This study briefly outlines the current methods used for Fabrication of mosquito repellent textiles using detoxification and decolorization of dye effluents stressing on the 21 herbal loaded nanoparticle importance of immobilized enzymes as a revolutionary biocatalytic solution to this environmental problem. Biodegradation of textile effluent immobilised The new treatment technologies with low energy consumption and 22 enzymes from weed plants(C.gigantea & possible recovery of valuable resources (e.g., energy and water) from D.metal) wastewater become of strong interest. Synthesis of iron oxide nanoparticles by the recently developed Waste water treatment and electricity 23 green approach is extremely promising because of its non-toxicity generation using MFC and CW-MFC and environmentally friendly behavior. Chitosan coating on fruits and vegetables has been found to be effective for the reduction of a variety of harmful micro-organism Photocatalysis of safranin using green 24 and extend the shelf-life of these products. It is widely investigated synthesized zinc oxide nanoparticle as an edible coating, which is defined as the formation of a thin film directly on the surface of the product they are intended to protect. Synthesis ,characterization and food Agriculture and phytoremediation efficiency may be significantly 25 preservative of chitosan improved by using Klebsiella sp.Klebsiella sp have proven effective in bioremediation of metals and influencing phytoremediation by phytoextraction or by phytostabilization in metal-contaminated soil Chemical control is an effective strategy used extensively in daily Plant growth promotion and enhancing life. An alternative to conventional chemical control is the utilization 26 phytoremediation using klebsiella spp. isolated of natural products from plants and essential oils an alternative from Eclipta prostarta source for larvicidal. Cell cultures pointed out a faster cell proliferation on glygel and a Investigating the potential of a bio insecticide 27 higher cell activation and differentiation on thermogel. These gels against mosquitoes could be used as scaffolds able to promote in situ bone regeneration. Development and characterisation of The results show the best degradation for methylene blue dye was at 28 biocompartable silk fibroin based hydrogel for the irradiation time of 5 hours and in the presence of UV source. in-vitro cell culture application This study is to reduce pollution load it is desirable to degrade the Photocatalytic degradation of Methylene Blue dye into non-toxic form before its discharge into the main stream. 29 by using copper oxide nanoparticles The present study reports the photocatalytic degradation of malachite green (MG). With the sharp increase in population and modernization of society, environmental pollution resulting from petroleum hydrocarbons has Photocatalytic degradation of Malachite Green 30 increased, resulting in an urgent need for remediation. Petroleum by using Titanium oxide nanoparticles hydrocarbon-degrading bacteria are ubiquitous in nature and can utilize these compounds as sources of carbon and energy. This technique hold a great promise for decontamination of heavy Screening of Oil Degrading Bacteria from metals from soil and water bodies with successful intervention of 31 Hydrocarbon Contaminated Soil interdisciplinary researchers, but challenges remain before commercialization and field scale application. 32 Phytoremediation and growth analysis of Due to its overall environmental impact, the residual dye in the Crossandra infundibuliformis in metal wastewater from the synthetic dye manufacturing and textile contaminated soil industries is a global concern. 1.
