Cladosporium resinae

Fall has studied the capability of fourteen species of microorganisms to grow on methoprene as sole carbon source. One of these organisms, Cladosporium resinae, was able to utilize methoprene as sole carbon source, while another. Pseudomonas citronellolis, was similarly able to utilize 7-methoxycitronellic acid. (41). 

In fuel systems containing water, certain microorganisms can survive. Typical species are the bacterial anaerobe Disulfovibrio and the fungal species Cladosporium resinae. These microorganisms are called hydrocarbon utilizing microbes and often referred to as HUM or HUM-bugs. They can initiate corrosion in fuel systems. 

Pateamine (49), a thiazole-containing macrolide with a 19-membered dilactone functionality, was isolated from the New Zealand marine sponge Mycale sp., collected on the southwest coast of the South Island of New Zealand. Pateamine (49) had potent in vitro antifungal (MIC values Candida albicans, 1 pg/ml Trichophyton mentagrophytes, 20 ng/ml Cladosporium resinae, 0.4 pg/ml) and cytotoxic... 

Fungal contamination and decomposition of hydrocarbons are well-documented phenomena [65-79]. The major limiting factor for microbial activity in fuels is availability of water [65]. The volume of water required for microbial growth in hydrocarbon fuels is extremely small. Since water is a product of the microbial mineralization of organic substrates, it is possible for microbial mineralization of fuel to generate a water phase for further proliferation. For example, Cladosporium resinae, the kerosene fungus, grew in 80 mg water per liter of kerosene and after four weeks incubation, the concentration of water increased more than tenfold [65]. 

Fonken, Murray, and Reineke (F-254) isolated testosterone acetate (stage 1) from the degradation of progesterone with Cladosporium resinae, thereby substantiating further the thesis of Fried, Thoma, and Klingsberg. They proved unequivocally, with appropriately labeled progesterone, that the 21-carbon atom of progesterone is the precursor of the methyl carbon atom of acetate in testosterone acetate.
