New polyenic antibiotics active against gram-positive and gram-negative bacteria. IX. Reclassification of a strain W-315 producing enacyloxins.

W-315was shownto be an "intermediate" strain among the genera Gluconobacter, Pseudomonas and Acetobacter6\ Since strain W-3 1 5 had characteristics similar to Gluconobacter, except for the absence of ubiquinone10 (Q10), we tentatively identified strain W-315as a Gluconobacter sp. Recently, we reexamined the generic placement of strain W-315 utilizing the additional data found in the new edition of Bergey's Manual of Systematic Bacteriology7). In this paper, we propose that strain W-315 be transferred to the genus Frateuria. Yamada et al.8) characterized the isoprenoid
