1. Apparatus useful for feeding a particulate starter material comprising nutrient and bacteria to a mixing tank, for solubilizing the starter material inside the mixing tank, for promoting growth of the bacteria and for discharging an aqueous slurry comprising the bacteria from the mixing tank, the apparatus comprising: a housing having a frame and a releasable cover;a particulate matter feeder unit;a feeder drive assembly supported by the frame and releasably engaged with the particulate matter feeder unit to allow dispensing of particulate starter material;a liquid flow control system;a mixing tank disposed at least partially below the particulate matter feeder unit to receive particulate starter material dispensed from the feeder unit;an aqueous slurry discharging device in fluid communication with the mixing tank that permits discharge of the slurry after sufficient residence time within the mixing tank;a microprocessor to control the feeder drive assembly and the liquid flow control system;a pressurized water supply controlled by the liquid flow control system to supply water to the mixing tank; anda power supply connected to the feeder drive assembly, liquid flow control system, and microprocessor;wherein the particulate matter feeder unit comprises a dam and, a rotatable feeder cup having a single feed chamber disposed below the dam, and wherein the dam and feeder cup cooperate to control a flow of particulate matter downwardly through the feeder unit;wherein the mixing tank comprises a bottom having a first drain port and wherein the frame comprises a lower support plate having a second drain port that is in fluid communication with the first drain port;wherein the aqueous slurry discharging device comprises a rigid overflow drain tube having a lower end that provides a fluid-tight seal at the first drain port and having an upper end that is at least partially disposed in a substantially central location inside the mixing tank;wherein the upper end of the rigid overflow drain tube comprises at least one inlet port and at least two oppositely disposed scuppers. 2. Apparatus useful for feeding a particulate starter material comprising nutrient and bacteria to a mixing tank, for solubilizing the starter material inside the mixing tank, for promoting growth of the bacteria and for discharging an aqueous slurry comprising the bacteria from the mixing tank, the apparatus comprising: a housing having a frame and a releasable cover;a particulate matter feeder unit;a feeder drive assembly supported by the frame and releasably engaged with the particulate matter feeder unit to allow dispensing of particulate starter material;a liquid flow control system;a mixing tank disposed at least partially below the particulate matter feeder unit to receive particulate starter material dispensed from the feeder unit;an aqueous slurry discharging device in fluid communication with the mixing tank that permits discharge of the slurry after sufficient residence time within the mixing tank;a microprocessor to control the feeder drive assembly and the liquid flow control system;a pressurized water supply controlled by the liquid flow control system to supply water to the mixing tank; anda power supply connected to the feeder drive assembly, liquid flow control system, and microprocessor;wherein the particulate matter feeder unit comprises a feed canister, a base having an aperture, a dam having an aperture, and a rotatable feeder cup having a single feed chamber disposed below the dam, and wherein the dam and feeder cup cooperate to control a flow of particulate matter downwardly through the feeder unit; andwherein particulate starter material from the feed canister fills the feed chamber when it is in alignment with the aperture in the dam and out of alignment with the aperture in the base and wherein particulate starter material is dispensed to the mixing tank from the feed chamber when it is in alignment with the aperture in the base and out of alignment with the aperture in the dam; andwherein the rotatable feeder cup comprises surface enhancements that contact the aperture in the dam when the feed chamber is out of alignment with the aperture in the dam to reduce the likelihood of bridging or jamming of the particulate starter material passing from the feed canister to the feeder cup. 3. The apparatus of claim 2 wherein the particulate matter feeder unit is preloaded with particulate starter material and is slidably engageable with the drive assembly so that when the starter material is consumed, the particulate matter feeder unit may be disengaged from the drive assembly, removed from the dispensing apparatus, and replaced with another pre-loaded particulate matter feeder unit. 4. Apparatus useful for feeding a particulate starter material comprising nutrient and bacteria to a mixing tank, for solubilizing the starter material inside the mixing tank, for promoting growth of the bacteria and for discharging an aqueous slurry comprising the bacteria from the mixing tank, the apparatus comprising: a housing having a frame and a releasable cover;a particulate matter feeder unit;a feeder drive assembly supported by the frame and releasably engaged with the particulate matter feeder unit to allow dispensing of particulate starter material;a liquid flow control system;a mixing tank disposed at least partially below the particulate matter feeder unit to receive particulate starter material dispensed from the feeder unit;an aqueous slurry discharging device comprising a pipe in fluid communication with the mixing tank that permits discharge of the slurry after sufficient residence time within the mixing tank;a microprocessor to control the feeder drive assembly and the liquid flow control system;a pressurized water supply controlled by the liquid flow control system to supply water to the mixing tank;scupper disposed near the upper end of the pipe; anda power supply connected to the feeder drive assembly, liquid flow control system, and microprocessor;wherein the particulate matter feeder unit comprises a dam and a rotatable feeder cup having a single feed chamber disposed below the dam, and wherein the dam and feeder cup cooperate to control a flow of particulate matter downwardly through the feeder unit;wherein the pipe is vertically disposed in a substantially central portion of the mixing tank, having a lower end in fluid communication with an aperture in a bottom surface of the mixing tank and an open upper end disposed at a desired level above the bottom surface of the mixing tank to permit the supply of a sufficient amount of water to grow bacteria from the particulate starter material before the water level reaches the upper end of the pipe to discharge the aqueous slurry. 5. Apparatus for dispensing an aqueous slurry comprising bacteria, the apparatus comprising: a feeder unit comprising a feed canister, rotatable feeder cup, and a base releasably attached to the feed canister, the feed canister comprising solid walls and an open end and containing pre-loaded particulate starter material comprising bacteria, the base and rotatable feeder cup each comprising an aperture to dispense particulate starter material from the feed canister to a mixing tank, the mixing tank being at least partially disposed below the aperture in the base;a feeder drive assembly releasably engaged with the feeder unit to rotate the aperture in the feeder cup into and out of alignment with the aperture in the base at predetermined intervals;two or more liquid mixing jets disposed inside the mixing tank in substantially equidistant locations to supply liquid to the mixing tank;an outlet for dispensing an aqueous slurry from the mixing tank, the aqueous slurry formed from particulate starter material and liquid combined in the mixing tank;wherein the apparatus is configured to allow the feeder unit to be slidably disengaged from the feeder drive assembly without the use of tools and removed from the apparatus when the starter material has been consumed and to be replaced with another feeder unit pre-loaded with particulate starter material;wherein the feeder drive assembly comprises a drive shaft and a plate that supports the base of the feeder unit; the aperture on the feeder unit base comprises a lip that engages with an aperture on the support plate; andwherein the base of the feeder unit further comprises a second aperture through which the drive shaft is disposed to provide rotational engagement with the rotatable feeder cup.
