A bacteriocin-like substance producing strain T12 was screened from 212 lactic acid bacteria isolated from intestine of healthy pigs by paper disk test and was identified as Lactobacillus. The supernatant of T12 exhibited strong inhibitory activity against the gram-positive bacteria, including Micrococcus lysodeikticus, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus. A strong activity was also observed against the gram–negative bacteria and some eumycete, such as Escherichia coli, Salmonella typhimurium and Fusarium graminearum.

The fungicidal activity of methanol extract was higher than that of ethyl acetate extract, and the inhibition rates were higher than 90% against Alternaria longipes, Fusarium oxysporium, Gibberella zeae, Glomerella cingulata, Exserohilum turcicum under the concentration of 1000g/mL The results of the inhibition of spore germination indicated that the fermentation products exhibited obvious inhibition rate against Alternaria longipes, Exserohilum turcicum and Fusarium coeruleum, the EC50 values was 59.4g/mL, 96.5g/mL and 132.5g/mL. In the bioassay of the fermentation products against Bacillus sub tills and Bacillus cereus, by means of detection fo inhibition zone, the inhibition zone diameter was 20mm and 27mm. The results of pot tests that methanol extract showed higher than 70% of protective efficacy and therapeutic efficacy against wheat powdery mildew under the concentration of 2000g/mL.

Cereus group strain was investigated in this paper. The result confirmed that MYP and PEMBA medium had high selectivity for this bacterium.

对三种常用BC选择性培养基进行了比较，证明MYP及PEMBA对Bc群微生物有良好的选择性。

Furthermore, MYP was more selective and easier to prepare than PEMBA. Thus, it is considered to be a selective medium for B. cereus group microorganism.

其中MYP制备方便，培养时间短，更适合作为Bc群微生物的常规鉴定培养基。
