A Study on the garbage decomposing Characteristics of the garbage-decomposing accelerant( I )

The characteristics of the commercial garbage-decomposing accelerant, Raw Material of Pomia(RMP), Pomia and Vitabio. were analyzed. In HPLC pattern, Pomia and Vitabio showed main peak of about 30kDa in 280nm wave length. RMP, Pomia and Vitabio showed three, two and two peaks in 210nm. K and Na ion content of RMP were 2,620 and 1,590ppm, respectively, and their content were the largest one among others. Ca, Mg and Mn ion content of RMP were also the largest one, but Zn ion content was the least one. $Cl^{-}$, $F^{-}$ and $NO_3^{-}$ ion content of RMP were the largest one, especially $Cl^{-}$ content was 3,553ppm. pH values of RMP and Pomia were in neutral region, but Vitabio was 9.03. Dried residue content of RMP, Pomia and Vitabio were 1.4%, 0.55% and 0.4%, respectively. The number of general bacteria on PCA plate from RMP, Pomia and Vitabio were 2.2{\times}10^{6}cfu/ml,{\;}6.5{\times}10^{3}cfu/ml{\;}and{\;}1.1{\times}10^{3}cfu/ml$, respectively. The number of facultative anaerobes of RMP was $4.4{\;}{\times}{\;}10^{4}cfu/ml$, and it was biggest one. Lactobacilli and yeasts were found less than 10cfu/ml at best. The bacterium exists in RMP in high frequency was identified as Bacillus subtilis. Volatile sulfur compound amount of garbage samples treated with Pomia and Vitabio in concentration of 1/500 at $33^{\circ}C$ for 8 days were 1,273ppb and 1,902ppb, respectively, and control showed 3,015ppb. Volatile organic compound amount of the garbage samples treated were 68,312ppb, 124,317ppb and 263,954ppm, respectively. Diethylamine that known as malodor compound were 5,107ppb, 261ppb and 11,124ppb, respectively.
