Biodegradation of a model mixture of hydrocarbon (dodecane and hexadecane, 1:1 w/w), as well as hydrocarbon emulsified by synthetic and natural emulsifiers, and their mixtures were analyzed in the presence of Pseudomonas spp. and Bacillus spp. bacterial strains. Changes in surface tension were measured by the static and dynamic methods during biodegradation processes. During the biodegradation ...

The detection and measurement of hydrocarbons are high interest for a variety applications, example within the oil gas industry from extraction throughout complete refining process, as well environmental monitoring portable safety devices. This paper presents highly sensitive, selective, robust tunable laser analyzer that has capability to analyze several components in sample stream. More speci...
