TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Method: The Bacillus species are B. subtilis, B. megaterium, B. polymyxa, B. licheniformis, B. uniflagellatus, B. lacterosporus, B. chitinosporus, B. amyloliquefaciens, B. pumilus, B. stearothermophilus, B. mycoides, B. sphaericus, B. coagulans, B. thuringiensis, B. lentus, B. circulars, B. badius, or B. firmus. The cell density of the inoculum is at least 108 or 1012 cells/ml. Preparing the inoculum comprises culturing a composition comprising 0.01-10 parts by weight of the mixture of Bacillus species, 1- 20 parts by weight of complex microbiological culture medium, and 70-98.99 parts by weight of water. The complex microbiological culture medium comprises whey protein concentrate, fish protein, poultry meal, molasses, or their mixtures. The complex microbiological culture medium further comprises humic acid. The complex microbiological culture medium further comprises Saccharomyces cerevisiae. The microbiological culture media further comprises S. cerevisiae. The method further comprises subculturing the enriched culture by taking an aliquot of the enriched culture, adding water, complex microbiological culture medium, and a selected amount of animal wastes, and then incubating the resulting mixture to result in a super-enriched culture. The method further comprises subculturing the super-enriched culture by taking an aliquot of the super-enriched culture, adding water, microbiological culture media, and a selected amount of animal wastes, and then incubating the resulting mixture. The mixture of the composition and the animal wastes is incubated for 12 hours to 14 days. Applying the enriched culture comprises spraying and mixing the enriched culture on a waste-containing lagoon. The selected volume of the inoculum is mixed with 1-4, preferably 3-4, times the selected volume of the animal wastes to be controlled. The method further comprises applying the enriched culture to the animal wastes to be controlled on a daily basis. EXAMPLE - A composition was prepared by mixing 0.03 parts by weight of Bacillus subtilis, 0.18 parts by weight of poultry meal (spray dried), 0.18 parts by weight of whey protein concentrate, 0.23 parts by weight of brewer's yeast, 0.23 parts by weight off-wash protein, 0.35 parts by weight of humic acid (derived from leonardite), 4.75 parts by weight of molasses, and 94.05 parts by weight of water. The mixture was incubated at 32.2degreesC. (i.e., 90degreesF.) for 7 days with agitation by pumping air through the mixture. The resulting culture was then ready to be subcultured. About 1893 liters (500 gallons) of the mixture was diluted with 5678 liters (1500 gallons) of liquid lagoon waste from a manure lagoon located on a dairy. The resulting mixture was then cultured at ambient temperatures for 14 days without agitation to result in an enriched culture. The enriched culture was then applied to the lagoon.
