Microbiological activities in the composting process : A review

Composting is a technological process of waste management that is, with the help microbiological activities in aerobic conditions, organic material decomposed and stabilized into biodegradable mixture transformed compost. This decomposition matter has recently attracted lot attention due to its environmentally friendly methods which additional environmental pollution avoided. The composting follows four phases (first mesophilic phase, thermophilic second maturation phase). most important factors influencing success are C/N ratio, humidity, temperature, substrate particle size, pH, oxygen content microorganisms. Microorganisms such as bacteria, fungi, actinomycetes act chemical decomposers carbon dioxide, heat, water, hummus, relatively stable final product - In composting, microorganisms decompose complex molecules lignin, cellulose, hemicellulose. presence different types influenced by composition composite mixtures changes temperature through process. At beginning compression, microbial activity increases significantly, causes rise. initial dominance bacteria replaced fungi active compost maturation.This scientific paper aims present an overview role beneficial mixture.
