Agricultural wastes are used to improve the digestive efficiency of Groupers on soy beans. Corn cobs are digested by xylanaseauxiliary proteins to produce xylooligos. The residues of corn cobs are then used to culture a probiotic which can secrete digestive enzymes. Xylooligos, digestive enzymes,probiotics are mixed with soy bean powders to improve the digestion efficiency of Groupers.

1. Using an environmentally friendly way to produce xylooliogs
2. Using cross-linked enzyme aggregates
3. Providing a wild-type probiotic which produces digestive enzymes
4. Agricultural wastes are used thoroughlyenvironmentally friendly
5. Improving the digestion of carnivorous fishes on soy beans
6. Strategies used can reduce costs

This technology can be applied in:
(1) The aquaculture of Groupers
(2) The aquaculture of other carnivorous fishes
(3) Other animal husbandry
(4) Functional food industry
(5) The treatment of other agricultural wastes
(6) Degradation of agricultural wastes for bioenergy production
