For cellular fatty acid analysis, cells of strain CNU040T and A. terrigena KCTC 12545T were grown aerobically on MA at 30 uC for 3 days. Fatty acid methyl esters were obtained by saponification, methylation and extraction using standard protocol of the MIDI (Sherlock Microbial Identification System, version 4.5). Fatty acids were analysed by GC (6890N; Agilent) and identified using the TSBA50 database of the Microbial Identification System (Sasser, 1990). The major respiratory quinones were analysed by HPLC (ZQ 4000; Waters) with a reversed-phase column (30063.9 mm Nova-Pak 130 C18; Waters) as described by Komagata & Suzuki (1987). Polar lipids were extracted according to the procedures described by Minnikin et al. (1984) and separated by two-dimensional TLC using 6.566.5 cm silica gel 60 F254 plates (Merck).
