Latest Research on Biodegradation : March – 2020

Biodegradation of polycyclic aromatic hydrocarbons

Polycyclic aromatic hydrocarbons, the products of the incomplete combustion of fossil fuels, are ubiquitous in nature. Some of these chemicals are of environmental concern because of their genotoxic and carcinogenic potential and their persistence in the environment. [1]

Control of biodegradation of biocompatable magnesium alloys

By utilising its rapid corrosion reaction and controlling its degradation process through Zn and Mn alloying, purification and anodization, chemically active magnesium can be developed into a biodegradable biocompatible implant material with a specific biodegradation process and tolerable hydrogen evolution rate, which may replace current problematic biodegradable polymers in applications. [2]

The mechanism of biodegradation of polyethylene

LDPE films have been exposed to abiotic and biotic environments. The films were UV irradiated for periods of 0, 7, 14, 26 and 42 days before being mixed with water and soil. [3]

Biodegradation Potentials of Aspergillus sydowii and Fusarium lichenicola on Total Petroleum Hydrocarbon in an Oilfield Wastewater in Rivers State

This study investigated the potential of Aspergillus sydowii and Fusarium lichenicola as mixed cultures in the biodegradation of Total Petroleum Hydrocarbons TPHs in oilfield wastewater. Oilfield wastewater was collected from an onshore oil producing platform and biodegradation of total petroleum hydrocarbons was investigated using standard methods. Fungi were isolated from oilfield wastewater contaminated soils obtained from the vicinity of the oil producing platform. Experimental control set-up and treatment with mixed culture of fungal isolates were periodically analyzed on days 7 and 21 intervals for total petroleum hydrocarbon degradation using Gas Chromatography (GC).

Biodegradation Potential of Bacteria Isolated from Crude Oil Polluted Site in South South, Nigeria

Aims: This study aimed to determine the biodegradative potential of crude oil by Chryseobacterium sp. and Lysinibacillus fusiformis isolated from Crude Oil site in Gokana LGA, of Rivers State. [5]
