The Activity of Potassium and Phosphate Solubilizing bacteria from Sugarcane Rhizosphere on Some Bagasse Condition Media Inoculated by Lignocellulolytic bacteria

Abstract

The main aim of this research was to study the activities of phosphate solubilizing (PSB) and potassium solubilizing (KSB) bacteria and lignocellulolytic on some conditions of bagasse media. Six conditions of bagasse were combined with lignocellulolytic bacteria as carrier media for PSB and KSB. Bacteria activity under observation included respiration, concentration of P-total, K-total, N-total, organic carbon, the change of C/N ratio, and the change in cellulose and lignin concentration. The research results corroborated that respiration of microbial increase from D+7 (seventh days) to D+28 (twenty-eighth days) on all condition of bagasse media with maximum respiration reaching11.14mg CO2/kg/day; the population of PSB and KSB are 97.67.107cfu.g-1 and 64.17. 107cfu.g-1; the concentration of K-total and Ptotal, N-total, C-organic and C/N ratio decreased on all treatments media during incubation respectively.
