Abstract (en)
[origin: WO2019168627A1] A method for improving the quality of pond water used in aquaculture applications by adding to the pond water active bacteria that are preferably germinated from spores on site using a nutrient-germinant composition and an incubation method for increased spore germination efficiency, in combination with a nitrification enhancement agent such as calcium carbonate or calcified seaweed, and an optional reaction surface area modifier such as calcified seaweed or plastic or metal particles or fragments. The nutrient-germinant composition comprises L-amino acids, D-glucose and/ or D-fructose, a phosphate buffer, an industrial preservative, and may include bacteria spores (preferably of one or more Bacillus species) or they may be separately combined for germination. The incubation method comprises heating a nutrient germinant composition and bacteria spores, to a temperature range of 35°C to 60°C for around 2 to 60 minutes to produce an incubated bacteria solution that is discharged to the aquaculture application.
