all the isolated cultures are re suspended by adding 1 ml sterile water and then each re suspended culture is inoculated into a flask which already contains sterile white water 100 ml and 3 g lbkp pulp later different dispersing agents are added into different flasks of each kind of culture to obtain different mixtures the mixtures are cultivated in an incubate shaker at 40 u00b0 c 70 rpm after being mixture cultivated for 3 hours 3 ml antagonistic c5 streptomyces bikiniensis which has been amounted to 10 7 ml after being cultivated for 24 hours is added thereinto to obtain another mixture the mixture are cultivated in the incubate shaker again at 40 u00b0 c 70 rpm after 7 days the production of the deposit is recorded 1 only incubate the antagonistic c5 without incubating the culture isolated from the slime and 3 only incubate the culture isolated from the slime without incubating the antagonistic c5 4 incubate both the culture isolated from the slime and the antagonistic c5 6 incubate the culture isolated from the slime the dispersing agent and the antagonistic c5 the groups described above are double checked and all experiments are repeated at least once deposit is calculated by the formula as follows deposit ue89e ue89e deposit ue89e ue89e dry ue89e ue89e weight ue89e ue89e of ue89e ue89e experimental ue89e ue89e group deposit ue89e ue89e dry ue89e ue89e weight ue89e.
