Agar plate method for detection and enumeration of alkylbenzenesulfonate-degrading microorganisms.
A simple method for detection and enumeration of alkylbenzenesulfonate (ABS)-degrading microorganisms by using agar plates was developed and used in microbiological studies of coastal marine and polluted river waters. The method depends upon the color responses of neutral red in alkaline medium. Neutral red changes from pink, when it enters into ABS micelles, to yellow, when the ABS is degraded...
متن کاملEnumeration of petroleum-degrading microorganisms.
A variety of factors, including concentration of oil, antibiotics, dyes, and inoculum washes, were examined to determine their effect on the total counts of microorganisms on oil-containing media. The media found to be best for enumerating petroleum-degrading microorganisms contained 0.5% (vol/vol) oil and 0.003% phenol red, with Fungizone added for isolating bacteria and streptomycin and tetra...
متن کاملEnumeration of heterotrophic bacteria in water for dialysis: Comparison of the efficiency of reasoner’2 agar and plate count agar
Due to the fact the incubation conditions may influence the microbiological evaluation of water for dialysis, the objective of the present study was the comparison of the efficiency of R2A and PCA media in the enumeration of heterotrophic bacteria in 193 samples of water collected in dialysis clinics from 12 cities in São Paulo, between October and December 2007. Results showed counts significa...
متن کاملA small-scale method for screening of lignin-degrading microorganisms.
A new method to facilitate rapid screening of lignin-degrading microorganisms was developed. Fungal strains are cultivated in tissue culture plates containing C-ring-labeled dehydrogenation polymerizate (DHP) (synthetic lignin). Evolved CO(2) is trapped in barium-saturated filter paper and is detected by exposing the paper to X-ray film. Analysis of the autoradiograms, carried out by density me...
متن کاملStudies with the Agar Cup-Plate Method: I. A Standardized Agar Cup-Plate Technique.
Official Circular 198 (Ruehle and Brewer, 1931) gives directions for performing the agar cup-plate test. However, in the limited literature dealing with the subject, no mention is made of the influence of varying the volume of agar, the amount of inoculum, the hydrogen ion concentration or other factors. In the course of other studies with the agar cup-plate method (Rose and Miller, 1939; Mille...
