Abstract
The present invention provides a process for the preparation of stable and reusable biosensing granules useful in the assessment of biodegradability of effluents. The biosensing granules are prepared by culturing active aerobic microbial consortia in synthetic medium, separating the active aerobic microbial consortia, immobilizing the microbial consortia using natural polymer to form biosensing granules, and dehydrating the immobilized biosensing granules to obtain stable biosensing granules having a moisture content of 5-30%.
Claims16
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%.
