Abstract
The present invention is a bacteria and nutrient delivery composition containing bran. The subject composition is preferably made in the form of a tablet that is structurally stable without being excessively hard. The tablets preferably have a configuration that reduces the likelihood of premature shearing in tableting presses or jamming in feeder devices for biomass generators. Methods of manufacturing the bacterial delivery composition in a structurally stable form that maintains bacterial viability are also provided.
Claims20
A method for making a feed material for a biomass generator in a pellet or tablet form, the method comprising:
- autoclaving bran to kill background microorganisms;
- producing a bran culture consisting essentially of bran, a fluid growth medium and non-spore forming Pseudomonas by applying to the autoclaved bran a fluid growth medium mixed with a waste-decomposing, bacterial culture of non-spore-forming Pseudomonas;
- incubating the bran culture under humidity;
- drying the bran culture;
- grinding the dried bran culture to smaller particles;
- and
- mixing with the ground bran culture one or more growth promoting nutrients to form a mixture;
- forming a tablet or pellet from the mixture;
- wherein the tablet or pellet comprises about 1 to 2 wt. percent bran and around 2-96.5 wt. percent total growth promoting nutrients, and wherein the Pseudomonas is present in an amount ranging between 0.1% and 10% of the total weight of the tablet or pellet.
