Abstract

 

Anoxybacillus sp. MGA110, a thermophilic cellulolytic bacterium, was isolated from municipal solid waste (MSW) composting and characterized by 16S rRNA sequencing. A pure culture of the isolated strain was applied to municipal solid waste composting as inoculum. The results of inoculation showed that the biodegradation of organic matter was quicker than the control as indicated by more reduction in C/N ratio. The inoculation increased duration of thermophilic phase, cellulase activity and number of thermophilic bacteria during the composting process. Hence, it can be concluded that inoculation with the isolated strain can accelerate composting process and promote biodegradation of organic matter as this reduces C/N ratio faster and increases cellulase activity more.
