Abstract: To discuss the bacteriostasis of extracts from aloe vera on Aeromonas veronii by juicing method, water extraction and alcohol extraction method, the inhibition activities, the minimal inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of the extracts from three kinds of methods which had significantly antibacterial effect against Aeromonas veronii were determined with K-B programe and the double broth dilution method. The results showed that the extracts from aloe vera with three kinds of methods all displayed sterilization ability on Aeromonas veronii inordinately. MIC of the extracts from aloe vera with juicing method, water extraction and alcohol extraction method were 1, 0.5, 0.125 g/mL, respectively. The MBC were 1, 1, 0.25 g/mL, respectively. Alcohol extract method showed higher activities than the others. But water extraction was considered as the most suitable method for extracting based on both of the antifungal activity and extraction efficiency.
