An organism that can happily grow in an extreme environment is an extremophile. The extreme envir-onments include physical extremes like pressure, temperature and radiation and geochemical extremes like desiccation, salinity, pH and low redox potentials.
The thermophiles are the extre-mophiles that can thrive superbly at high temperatures. They have developed such enzyme systems that can help the organisms not only to survive at higher temperatures but also grow and reproduce. They have ability to use sulphurous waste and convert it into non-toxic products. Since the environment for such microorganisms sustains higher temperatures, many spoilage and pathogenic organisms cannot survive in such extreme conditions. Therefore it would be ideal if we can make use of these organisms to degrade the kitchen waste to remove more toxic elements and then subject it to the traditional biogas plant for methane generation. What we need to do is to maintain the high temperature in the predigestor tank.
