Isolation and Deodorization Characteristics of Two Strains of Lactic Acid Bacteria

Two strains of lactic acid bacteria, named as LP and ST, were isolated from kimchi wastewater and anaerobic sludge. According to its morphological and the analysis of 16S rDNA gene sequence, strains LP and ST were identified as Lactobacillus plantatum and Streptococcus thermophilus, respectively. Thehighest removal rates of NH3 and H2S by L. plantatum were 54.87% and 37.35%, respectively. The highest removal rates of NH3 and H2S by S. thermophilus were 40.99% and 22.47%, respectively. For the mixture of the two strains, thehighest removal rates of NH3 and H2S reached 90.74% and 63.58%, respectively. The antagonist and symbiosis experiments showed no antagonistic inhibition between the two strains, but remarkable synergistic effect on deodorization. Fig 6, Tab 1, Ref 12
