Abstract: Biocides are the more worldwide used chemical compounds for the biodeterioration treatment, and they arespecific for different fuels. In this article it was evaluated the Biobor J.F. antimicrobial activity in vitro, the Liquid 1 andsix natural extracts (Quinidine trep, Quinidine, Colophony (2 mg/mL), VN (2.1 mg/mL), AR (2 mg/mL) and the extractT2-CIIQ). Germs from the, Pseudomonas, Bacillus and Micrococcus and the fungus of the species Hormoconis resinae,Aspergillus versicolor, Aspergillus niger and Alternaria alternate, isolated from contaminated fuels. The determinationof the minimum inhibitory concentration (MIC) was made by the radial diffusion method in monolayer of agarized atmosphereand the minimum germicide concentration (MGC) and the minimum fungicide concentration (MFC) weredetermined by the serial double dilutions method in culture with transfers to solid environment. The Biobor J.K. andthe Liquid I showed an inhibition microbial with the pure product. The germicide and fungicide activities were effectiveonly with the products which haven’t been diluted. The Quinidine treq and Quinidine extracts had a 12.5 μg/mL MIC forboth germs and fungus. The T2-CIIQ MIC has a value of 30 μg/mL coinciding with the MGC and the MFC. The Biobor J.F.and the Liquid I showed an antimicrobial activity without dilute. The Quinidine and T2-CIIQ extracts offered germicideand germistatic actions to low concentrations: 12.5 and 30 μg/mL respectively.
