Taxonomic value of the property of fungi to assimilate hydrocarbons

Biodegradation of crude petroleum oil and environmental pollutants by Candida tropicalis strain

“…In contrast, Serratia marcescens OCS-21 and Acinetobacter calcoaceticus COU-27 attacked long chains n-alkanes, probably because of the less toxic nature of the long chain n-alkanes rather than short chain as reported by Atlas and Bartha (1981) and Ijah (1998). On the other hand, the tested yeast could not metabolize or degrade naphthylamine and naphthalene 2-sulphonate, due to their lethal effect as reported by Nynes et al (1968). The ability of C. tropicalis A, to degrade long and short chain hydrocarbons could be attributed to having a very efficient degradative enzyme system.…”

Hydrocarbon-degrading filamentous fungi isolated from flare pit soils in northern and western Canada

“…Early studies on hydrocarbon-degrading fungi focused on filamentous soi1 fungi (Hyphomycetes; Davies and Westlake 1979;Flippen et al 1964;Hoffman and Rhem 1976;Markovetz et al 1968;Nyns et al 1968;Perry and Cemiglia 1973;). In 1985, Bumpus et al reported the oxidation of polycyclic aromatic hydrocarbons (PAHs) by the wood-decay basidiomycete Phanaerochaete chrysosporiurn, an observation that influenced the re-direction of research from hyphomycetes to basidiomycetes (white rot fungi).…”

“…The presence of a rnonocarboxylic acid, a prirnary alcohol and a secondary alcohol from a C. blakesleeana extract was detected. Nyns et al (1968) tried to assign a taxonomie value to the ability to assimilate hydrocarbons in sorting among taxa of filamentous fungi. Strains of unspecified origin were inoculated on slants of Yeast Nitrogen Base agar containing 3% sucrose.…”

“…Species from the genera Aspergillus, Fusarium and Penicilliurn showed the most growth, however this ability was not consistent among al1 strains of any aven species. Nyns et al (1968) further tested these strains on individual hydrocarbons using the same method. Very few strains were capable of growth on n-alkanes of less than ten carbon atoms, whereas n-paraffins of 12…”

An Evaluation of Some Physiological and Biochemical Methods as an Aid to the Characterization of Species of Penicillium Subsection Fasciculata

“…Moreover, hydrocarbon assimilation and specific enzyme activities have been investigated for use as taxonomic characters (Nyns et al, 1968;Bridge & Hawksworth, 1984). The number and types of secondary metabolites produced have also been used to divide the species Penicillium viridicatum into subgroups (Ciegler et al, 1973(Ciegler et al, ,1981, and this approach has been extended by the inclusion of a small number of physiological tests to differentiate a number of species within the genus (Frisvad, 1981 ;Frisvad & Filtenborg, 1983).…”
