Chromium (Cr) Biosorption, from High Energy Battery (Heb) Effluent Using Fungi
In the current industrialized world, uses of batteries have gained importance asa result of its high performance and energy storage system. Though, battery wasconsidered safe and produced less carbon foot print, it also has its ill effects suchas heavy metal contamination in water and soil, which is also at its thresholdto be addressed. Here comes the concern, about the elevated heavy metalconcentration especially chromium in the environment and its health hazardsexerted over all living organisms. Thus, as an approach towards the bio sorptionof chromium from environment, fungal isolates obtained from soil samples of HEBeffluent were screened for their resistance and efficiency. Among the 36 fungalisolates attained, Aspergillus was found to be most predominant in both easternand western area, as well as more resistant to chromium even at 1000 ppm.On further optimization of pH, Temperature, incubation period, carbon source,nitrogen source and phosphorous, it concluded that medium with Glucose, maltextract and potassium dihydrogen phosphate at pH 5 showed significant growthand proficient absorption of chromium under static condition. The 18s rRNA genesequencing of the effectual organism revealed to be Aspergillus niger (KY354579)with 99 % according to BLAST analysis.
