Fast production of enriched biocompost from sugarcane baggase using biotechnological process

The objective of the present study was to optimize fast production of enriched biocompost from sugarcane bagasse using native effective microorganisms and also other available materials. Four native bacterial strains with high hydrolase activities were produced at their optimized fermentation conditions. The compost production experiments were performed in the format of completely randomized design (CRD). Bagasse, filter cake and vinasses were used as base materials in all treatments (exception for control). The microbial cocktail (106-107 cells/g waste), chicken manure or urea was used as improvers. The treatments were as follows: T1- chicken manure and microbial cocktail, T2-chicken manure, T3- urea and micronial cocktail, T4- urea, and T5- control (only bagasse). The maximum temperature increase (upo to 58°C), the maximum C/N ratio (15.9) and EC reductions was observed for T1, followed by T2. The highest phosphorous (1.1%), potassium (1%), total nitrogen (2%) and nitrate (210 mg/kg) and also the lowest ammonia (67 mg/kg) contents were observed in T1. Evaluation of the phytotoxicity effects of the produced composts on cress (Lepidium sativum) seeds germination showed that the fastest and maximum germination was observed for T1 and T2, respectively. The wheats cultured on the compost produced from T1 showed significantly higher height, and fresh and dry weights compared to other treatments. So, the results of the present study showed that the presence of microbial strains ans chicken manure enhanced a significant reduction inprocess period, compost maturity and finally production of high quality compost from sugarcane wastes.
