In the phase I, Lactobacillus Casei Shirota inYakult was used as the seed, while Lactobacillus kefiri and Lactobacillus acidophilus were selected as the seed in the phase II. The substrate used in the study was dry manure. In phase II, Lactobacillus kefiri and Lactobacillus acidophilus were used separately to start up fermentations at two different moisture contents, 70% and 90%. After finishing the above experiments, tests of using the mixed culture of the above two species were conducted at 70% and 90% moisture contents consequently. The results showed that at moisture content of 90%, more protein content in the product was observed; and higher concentration of lactic acid appeared in the moisture content of 70%. In comparison of the efficiency of Lactobacillus, the results indicated that fermentations of Lactobacillus acidophilus on the 21st day and mixed Lactobacillus sp .on the 14th day, the highest protein content and higher crude fat content could be obtained for both at 90% of moisture content.
