Fungi consortia in situ biodegradation of xenobiotic, military shooting range, Kachia, Kaduna, Nigeria

Abstract

A major limitation of the white-rot fungus is its sensitivity during biodegradation of mixed matrix explosive pollutants and the scale of Kachia military shooting since 1967, Nigeria. The amplified 16S rRNA gene of each microbial isolate was processed for sequencing and characterization with Gene Bank database. Fungal species heavy metal reduction in increasing order of Aspergillus niger > Trametes versicolor > Rhizopus spp > Phanorochate chrysoporium > Penicillium spp were identified. The total explosive contents shows a significant difference for all locations in both dry and wet seasons (P<0.05) using Anova test. Microbial fungi consortium (MFC) bioremediate heavy metal significantly at 61.7% relative to isolated fungi species because of the lateral gene transfer/co-metabolism, where Trametes versicolor and Aspergillus niger act as gene mediators. MFC growth in 1% mineral salt medium munitions was significance than fungal species isolate. Deploying Myco Bio-augmentation / Phytoremediation/Biosimulation (Myco B-P-B) techniques to optimize the RDX and HMX characterized by a higher Nitrogen/Carbon ratio since fungi lack the beta-glucuronidase (GUS) gene to utilize carbon source directly. Pollutants bio-stimulation will enhances co-metabolism by MFC. Plant detoxification capabilities can be improved using fungi genes laccases and cytochrome P450 monooxygenase expressed effectively in plants using protoplast fusion
