DESCRIPTION OF
NONOMURAEA MESOPHILA
SP. NOV.
Nonomuraea mesophila
(me.so
′
phi.la Gr. n.
mesos
middle; Gr. fem. adj.
philos
loving; N.L. fem. adj.
mesophila
middle temperature loving).
Aerobic, Gram-stain-positive, non-motile actinobacterium that forms extensively branched substrate and aerial mycelia. Aerial hyphae differentiate into spore chains with smooth surfaces. Good growth occurs on ISP 2, ISP 4, modified Bennett’s and tryptic soy agar and moderate growth on Czapek’s, nutrient and ISP 5–7 agar. A range of substrate mycelial pigments are formed including cream, light brown, dark brown, reddish brown, reddish black or claret red ones. Melanoid pigments are not produced on the ISP 6 agar. Red coloured diffusible pigments are observed on modified Bennett’s agar. Grows from 20–37 °C (optimum, 28 °C), from pH 6.0–8.0 (optimum, pH 7.0) and in the presence of up to 5 % (w/v) NaCl. Hydrolyses aesculin, reduces nitrate, but does not produce H
2
S, does not hydrolyse allantoin, arbutin or urea. Degrades hypoxanthine, starch and Tweens (20, 40 and 80), but not adenine, casein, chitin, gelatin, guanine, xanthine or xylan. Adonitol, D-arabinose, D-fructose, raffinose, cellobiose, D-galactose, melezitose, melibiose, dextran, D-glucose, inulin, lactose, D-maltose, D-mannitol, sucrose and D-xylose are used as sole carbon and energy sources but not D-sorbitol, D-mannose, dextrin, L-sorbose, L-arabinose, L-rhamnose, L-glutamine, myo-inositol, sodium succinate or xylitol. L-Alanine, L-arginine, L-asparagine, L-cysteine, glycine, L-hydroxyproline, α-isoleucine, L-methionine, L-phenylalanine, L-proline, L-serine, L-tyrosine and L-valine are utilized as sole nitrogen sources, but not L-histidine. The predominant menaquinones are MK-9(H
4
) and MK-9(H
6
). The polar lipid profile include diphosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, dihydroxy-phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol, two unidentified aminophospholipids, an unidentified glycophospholipid, four unidentified phospholipids and an unidentified lipid. Whole-cell hydrolysates include

and C

10-methyl. The DNA G+C content of strain 6K102
T
is 70.8 mol% and its genome size 10.14 Mbp.
The
type
strain,
