Action of micro‐organisms on bituminous materials. II. Composition of low molecular weight asphaltic fractions determined by microbial action and infra‐red analyses
Abstract:Assay of narrow fractions from three asphalts designated 1A, 3A, and 6A indicates the chemical nature of some of the asphaltic constituents utilised by Mycobacterium ranae and Pseudomonas 196Aa. These organisms were tested with pure hydrocarbons for growth response. The results indicated that Ps. 196A utilised n‐alkanes containing 6—22 carbon atoms, some alkenes and fatty acids but none of the aromatic hydrocarbons tested. M. ranae utilised substituted benzene compounds, but not benzene, alkenes or most alkane… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
