title: [Determination of the enzymatic traits of anaerobic gram-negative nonsporulating bacteria].
abstract: The method requiring the use of a semi-liquid medium with the reduced content of protein hydrolysates and with bromo-thymol blue added as indicator and permitting the determination of sugar fermentation by bacteroids and fusobacteria is presented. The determination is made by a change in the color of the indicator and the intensity of microbial growth (opacity) after the incubation of the inoculated medium under free access of air. A study has been made for comparing the above method with the electrometric method for the determination of fermentative features in anaerobic microorganisms.
