Abstract

Long-chain saturated fatty acids (C(13) to C(18)) and fatty alcohols (C(12) to C(18)) were well utilized by three different soil isolates of Cladosporium resinae as the sole carbon and energy sources in static liquid cultures. Shorter-chain compounds, down to C(5), did not support growth and were in fact toxic towards the fungus growing on glucose. Rapid and considerable potassium efflux, protein leakage, and inhibition of endogenous respiration were observed in the presence of the shorter fatty acids and alcohols. Possible mechanisms and significance of the toxicity are discussed.

摘要

长链饱和脂肪酸(C(13)至C(18))和脂肪醇(C(12)至C(18))可被三种不同的树脂枝孢土壤分离株在静态液体培养中作为唯一的碳源和能源良好利用。短链化合物,直至C(5),不能支持生长,实际上对在葡萄糖上生长的真菌有毒。在较短的脂肪酸和醇存在下,观察到快速且大量的钾外流、蛋白质泄漏以及内源性呼吸的抑制。讨论了毒性的可能机制和意义。
