Degradation of long chain n-alkanes by Mucorales

Degradation of long chain n-alkanes by mucorales

“…All isomeric ketones and alcohols with chain lengths adequate to the alkane used were formed by the mould, as already concluded from the mass spectra of the difficult separable mixtures of oxidized alkane derivatives (Hoffmann & Rehm, 1976b). Moreover, in the region of ketones, numerous small peaks were discovered which to some extent showed a molecular ion (M +) at m/e 200 in the MS.…”

“…Quantitative estimations of the amounts of isomeric esters, which were found after 14 days in 400 ml substrate containing 2 % dodecane were performed by comparison of their peak areas with that of the previously (Hoffmann & Rehm, 1976b) determined 3-dodecanone.…”

“…Greater amounts of degradation products could be found in the substrates of Mortierella isabellina (CBS 224.35) than in those of other tested Mucorales (Hoffmann & Rehm, 1976b). Greater amounts of degradation products could be found in the substrates of Mortierella isabellina (CBS 224.35) than in those of other tested Mucorales (Hoffmann & Rehm, 1976b).…”

Lipid Biochemistry of Fungi and Other Organisms

“…It has also been shown that certain filamentous fungi degrade alkanes (Pelz and Rehm, 1973;Cerniglia and Perry, 1974;Gerasinova et al, 1975). For example, certain Mucorales fungi such as Absidia spinosa, Cunninghamella echinulata, and Mortierella isabellina metabolize C13 to C17 n-alkanes in the terminal and subterminal positions (Hoffmann and Rehm, 1976;1978).…”
