    Isolation and growth optimization of fungus from thermophilic phase of composting
    (UMT Lahore, 2020) Aqsa Shehzadi
    Stimulated by exponential growth population and increase consumption proportionality, organic waste has become a crucial environmental issue. Composting is the simplest method of reducing the organic waste encourages the production of beneficial bacteria and fungi that break down organic matter to create humus or compost. It is a self-heating biological conversion, which generates a suitable end product such as biofertilizer. Thermophilic phase accelerates the degradation of organic waste or complex carbohydrate, because temperatures above 400C. Thermophilic fungi are of wide interest due to their potential to produce heat-tolerant enzymes for industrial and biotechnological processes. This study is designed to optimize the parameters for isolated fungi from thermophilic phase of compost in order to determine best composting decomposition condition. Various parameters such as pH, temperature, EC, biomass were investigated to evaluate the effect on growth rate of fungus and for the production of lipase enzyme and α-amylase enzyme. To determine the suitable conditions, fungus was grown at different temperature and pH. Isolated fungus was active in acidic pH of 5.5 and 450C temperature. It was rapidly determined that the optimization of compost’s parameter promotes the decomposition rate, stability of the final product and better humification process. Therefore, more research ought to be done on this phase, in order to further optimize the composting process and reduce the time of composting process.
