Among the six natural strains, B. subtilis, B. laterosponus, P. aeruginosa had relatively higher TOC degradation
ability with rmax of 54%, 52%, and 43%; respectively. However, Pseudomonas aeruginosa had slightly greater qmax
(0.59 mgTOC/(d-mgVSS) and shorter Ts (10h). These results revealed that Pseudomonas aeruginosa was the most
effective strain for degrading the organic substrate (glucose) in the synthetic wastewater. However, the natural
local strains showed much less degradation (20-40% less) when compared to the SludgeHammer bacteria (see Fig
2). From the kinetic parameters in Table 1, this bacteria had the greatest rmax (71%) and the shortest Tlag (
