Abstract

Cold-adapted strain of Geomyces pannorum P11 was found to mineralize of phosphorus-carbon bond-containing compound--2-aminoethylphosphonic acid (2-AEP, ciliatine). The biodegradation process proceeded in the phosphate-independent manner. Ciliatine-metabolizing enzymes' activity was detectable in cell-free extracts prepared from psychrophilic G. pannorum pregrown on 4 mM 2-AEP. Phosphonoacetaldehyde hydrolase (phosphonatase) activity in a partially purified extract was demonstrated at 10 °C.

摘要

冷适应菌株 Geomyces pannorum P11 被发现能够矿化含磷-碳键的化合物——2-氨基乙基膦酸（2-AEP，纤毛素）。生物降解过程是在不依赖磷酸盐的方式下进行的。从在 4mM 2-AEP 上预培养的嗜冷 Geomyces pannorum 制备的无细胞提取物中可以检测到纤毛素代谢酶的活性。在部分纯化的提取物中，10°C 时表现出磷酰基乙醛水解酶（磷酸酶）活性。
