Abstract
The present invention provides a novel process of neutralizing textile industrial wastewater by a bacterial strain isolated in India. The isolated bacterial strain is capable to bring down the pH of wastewater from 12.00 to 7.00 units within two hours. The neutralization of alkaline textile industrial wastewater by such biotechnological process is highly effective and economical as compared to conventional neutralization by chemical means. This biotechnological process may find wide commercial application in textile industries emanating alkaline wastewater.
