Effluent from anaerobically treated swine wastewater was
first sanitized using sodium metabisulfite (Na2S2O5) at 0.2 g
L-1 for a day and diluted with distilled water to produce
dilution percentages of 0, 10, 20, 40, 60, 80 and 100 in a 20-
L container with a size of 5 L. S. platensis stock solution
(OD560 at 1.0) with 10% dilution was added. The
experiment was replicated three times in a Completely
Randomized Design. The cultures were maintained for 14
days with sufficient aeration.
