AMI is a microbial consortium developed by DRDE (Defence Research & Development Establishment), Gwalior, India. We manufacture the AMI under License from DRDE, Ministry of Defence, Govt of India.
AMI is a mixture of different types of bacteria (Hydrolytic, Acidogenic, Acetogenic and Methanogenic groups) responsible for breakdown of complex polymers into simple sugars which are further broken down into low chain fatty acids and finally into biogas. The AMI has been developed by enriching a desired group of bacteria from mixture of microbes by natural selection. The efficiency of the consortium was improved by fortification of several critical species of bacteria (Proteolytic bacteria) isolated from cold habitats like Antarctica, Leh and Siachen glacier areas. The AMI was also augmented with Volatile Fatty Acids degraders and has been gradually adapted to grow even at 5°C so that it can work efficiently at mesophilic as well as psychrophilic temperature. AMI efficiently degrades human waste at temperatures as low as 5°C and as high as 50°C.
AMI is the heart of the BIO-DIGESTER System and essentially required to digest the human waste matter by anaerobic bio-degradation process which happens in four sequential steps namely
- Hydrolysis
- Acidogenesis
- Acetogensis
- Methanogenesis
The last two processes are very poorly understood and are very sensitive at low temperatures. Low temperature operations need low temperature active bacterial inoculum for efficient bio-degradation.
In the anaerobic degradation / digestion process each of the above step is dependent on each other for food and energy requirement and every step is performed by specific class of microorganisms which are present in the Anaerobic Microbial Inoculum manufactured and supplied by us.
