The carbon sources of 96-well plate are shown in Table 2.
The sample suspensions (prepared from 5 g compost matrix and
45 ml 0.85% sterilized NaCl solution) were shaken for 2 h and then
kept still for 1 h to settle down their organic matters. Then, the sus-pensions were diluted 10 times to form 103
solutions and 150 llof
each 10 3
solution were taken and inoculated on the microplates
