Recovery of Manganese from Low-Grade Ferromanganese Ores Using Bacillus Safensis

The present investigation aims for the betterment of an environmental friendly procedure to extract Mn from mining desecrates using native microorganism. A single bacterial strain viewing noticeable growth on Mn-supplemented agar plate was isolated from the collected ore samples from Mn mining deposits of Joda Barbil districts of Odisha state of India. Molecular characterization of selected isolates conducted by the 16S rRNA sequencing method and the selected strain was taxonomically characterized as Bacillus safensis with genebank accession number (MF409013). Bioleaching experiment was conducted in 250 ml flask with optimum process conditions and Bacillus safensis as inoculum. Manganese extraction of 80% was monitored in the period of 20 days. The acknowledged bacterial strain exposed an eminent tolerance and solubilizing capability. The existing study brings light on the greener substitute for the extraction and recycling of manganese from the waste materials.
