Managing Wastewater Using Plastic Eating Bacteria - A Sustainable Solution For Sewage Fed Fisheries

YAffluent like plastics has made the water management issues of sewage fed fisheries much more difficult as well as cost-ineffective. However, possible impact of introduction of bacteria in managing plastics in wastewater for sustainable sewage fed fisheries operation has not been yet documented. Present study is an attempt to investigate whether Ideonella sakaiensis can be used to eradicate problems with plastics in sewage water so that fisheries operation can be continued in a sustainable way. The objective is to find the best suitable degradation procedure of various kinds of plastic involving biological means as well as other sources of natural means too. Bacterial and fungal species were also widely employed in these degradation processes. Several strains of Ideonella sakaiensis were used in developing the desired process. It was observed that, the hydrocarbon, present in plastics, can be degraded by organisms which can also use it as proper sources of carbon and these organisms can be employed. The outcomes are established by the changes in weight differences, tensile strength and reduction in the viscous properties in most of the instances while in few cases, molecular weight distribution, and fragility was also noticed. Thus it can be also concluded that HDPE plastics shows more resistance to soil conditions than that of the LDPE plastics. Further, Ideonella sakaiensis as a species does not pose any threat to the growth and cultivation of fishes. Thus in near future, plastics causing pollution in wastewater can be treated using this special variety of bacteria for improvement of fish cultivation.
