Abstract Cyanide is highly toxic to our ecosystem. The main contributor of cyanide
to the environment is the untreated or improperly treated wastewater coming from
various industries like steel, metallurgical, mining, tanning, etc. Bioremediation is
an inexpensive yet effective measure, compared to physico-chemical methods, for
removal of cyanide from industrial effluents. In the present study, one indigenous
bacterial strain was collected and isolated from the outfall of nearby coke-oven
plant and identified as Bacillus sp. NITD 19 through 16S rRNA gene sequencing.
The test strain was used for removal of cyanide from synthetic solution. Lethal
dose analysis was performed and the strain was found to grow up to 100 mg/L
initial cyanide concentration. One factor at a time (OFAT) analysis was performed
to get the effective operational parameters for maximum removal by varying pH
(6–10), inoculum load (1–4%), temperature (25–37
o C), and initial concentration
