Abstract
Disclosed herein are microbiome-based compositions for reducing and/or eliminating target compounds from water within recycled aquaculture systems. This disclosure also relates to methods for preparing dynamic microbiome-based compositions, and methods for deploying the dynamic microbiome-based compositions into recirculating aquaculture water systems.
Claims24
A composition for deploying into water of a recirculating aquaculture system (RAS), the composition comprising:
- (a) an enriched microbiome that is configured to reduce an amount of a target compound by a desired amount within the water;
- and
- (b) a carrier that is configured to induce the enriched microbiome to produce a biofilm or to sequester at least a portion of the target compound from the water or both.
A method for preparing a microbiome-based composition for deploying into water of a RAS, the method comprising:
- (a) selecting a microbiome sample from a water source that has been exposed to a target compound;
- (b) preparing an inoculum from the microbiome sample;
- (c) enriching the inoculum to produce a microbial consortium that degrades, consumes or otherwise converts one or more target compounds in the inoculum by culturing the inoculum in a medium that contains the one or more target compounds to produce an enriched microbial consortium;
- (d) culturing the enriched microbial consortium in a suitable nutrient medium for producing greater quantities of the enriched microbial consortium.
A method for preparing a microbiome-based composition for deploying into water of a RAS, the method comprising:
- (a) selecting a microbiome sample from a water source that has been exposed to an unrelated metabolic target compound, wherein metabolizing of the unrelated metabolic target compound results in degradation of a target compound;
- (b) preparing an inoculum from the microbiome sample;
- (c) enriching the inoculum to produce an enriched microbial consortium that degrades, consumes or otherwise converts one or more target, off-flavour compounds in the inoculum by culturing the inoculum in a medium that contains the one or more target, off-flavour compounds, the unrelated metabolic target compound or both to produce an enriched microbial consortium;
- (d) culturing the enriched microbial consortium in a suitable nutrient medium for producing greater quantities of microbial consortium.
A filter for use with a recirculating aquaculture system, the filter comprising:
- (a) a surface;
- (b) a microbiome aggregate adhered to the surface, wherein the microbiome aggregate comprises an enriched microbial consortium in a suitable nutrient medium for producing greater quantities of microbial consortium;
- and
- (c) a biofilm and wherein the enriched microbial consortium is configured to reduce an amount of a target compound within water that passes along the surface.
A recirculating aquaculture system (RAS) comprising:
- (a) a holding tank for holding a body of water;
- (b) a waste removal system that is configured to reduce one or both of chemical waste or solid waste within the body of water;
- (c) one or more conduits for fluidly connecting the holding tank and the waste removal system;
- (d) a pumping system for circulating water through the one or more conduits;
- and
- (e) a microbiome aggregate that comprises an enriched microbial consortium adhered to a surface of a carrier by a biofilm and wherein the enriched microbial consortium is configured to reduce an amount of a target compound within body of water.
