Abstract:
Five-day seeded Biochemical oxygen demand (BOD) tests using Glucose-Glutamic acid (GGA) substrate were carried out. The seeds used are a regular seed an NX seed and an over-the-counter food supplement commonly referred to as a probiotic. The purpose was to determine if seed type influenced 5-day BOD test results. The NX seed contained a chemical formulation designed to inhibit nitrification. Test results indicate that 5-day BOD varied significantly with each seed. Micrographs of stained samples prepared from cultures of the three seeds identified Gram-stain negative rods present in all the three inoculates.
Keywords:
