E-biodegradation using microbial consortium by the incorporation of Cobalt Ferrite Nanoparticle as the enhancer for biodegradation”

Abstract

Plastics are the synthetic materials created out of the fossil fuel resources. As a result they remain in the
environment for a very long time without any degradation because of microbial attack resistance. It has given rise to
serious threats to the environment due to its poor waste disposal. Plastics have various drawbacks like inducing lower
water absorption of soil, reduction in the fertility of soil. Therefore, the degradation of Low Density Polyethylene
(LDPE) by mixed microbial consortium with Nanoparticles seems to be a good choice.Nanoparticles studies have shown
their ability to degrade the synthetic polymer with the help of microbes. Cobalt Ferrite Nanoparticle with size ranging
15-40 nm were synthesized and characterized through XRD, FT-IR spectra, simultaneous TG-DTG-DTA, vibrational
sample magnetometry (VSM) and transmission electron microscopy (TEM).Nanoparticles influence exponential and
stationary phase. It acts by reducing the duration of lag phase and increasing the duration of exponential and stationary
phase. These nanoparticles influence the growth profiles of LDPE degrading microorganisms and enhance the rate of
Biodegradation. This review has its emphasis on LDPE degradation aspects of mixed consortium associated with
Nanoparticle act as enhancers of biodegradation
