Cooperative Interaction between the Seeded Bacteria in Bio-Enhanced Activated Carbon Filter
Abstract:
In this study, the fluorescence in situ hybridization (FISH) was used to specifically detect the seeded bacteria Pseudomonas sp and Bacillus subtilis in the BEAC filter. For evaluating the cooperative interaction between the seeded bacteria, Lotka-Volterra model was introduced to calculate the data gained from FISH results. The parameter α measures how much species Pseudomonas sp. inhibits species Bacillus subtiliss growth, and β measures how much species Bacillus subtilis inhibits species Pseudomonas sp..α=0.0063<K1/K2 and β=0.73<K2/K1 in the top section of the BEAC filter.α=-0.13<K1/K2 and β=0.41<K2/K1 in the middle section of the BEAC filter.α=0.66<K1/K2 and β=0.30<K2/K1 in the bottom section of the BEAC filter. The seeded bacteria Pseudomonas sp. and Bacillus subtilis could coexist in the BEAC filter. The bio-enhanced technology used here is a promising approach to introduce and maintain the seeded bacteria.
