Abstract:
1. A process for preparing stable and reusable biosensing granules useful in assessing biodegradability of an effluent, said process comprises the steps of: i. culturing active aerobic microbial consortia in a synthetic growth media, wherein the aerobic microbial consortia is collected from raw sewage, wastewater treatment plants or from activated aerated sludge units, ii. separating the active aerobic microbial consortia from the synthetic media, iii. immobilizing the active microbial consortia using a natural polymer to form immobilized biosensing granules, and iv. dehydrating the immobilized biosensing granules at 24-36° C. for a period of 2 to 20 hours, to obtain stable biosensing granules having a moisture content of 5-30%.
