Description of
Amycolatopsis marina
sp. nov.
Amycolatopsis marina
(ma.ri'na. L. fem. adj.
marina
of the sea, marine).
Cells are Gram-positive, aerobic and non-motile and produce white aerial mycelium sparsely on ISP
2
agar medium. The branched yellow to yellow–brown substrate mycelium fragments into rod-like elements. No diffusion pigments are produced on any of the media tested. Catalase-positive and oxidase-negative. Negative for urease and negative for reduction of nitrate to nitrite. H
2
S is not produced. Growth occurs between pH 6.0 and 9.0, between
10
and
45
°C and between
0.5
and
12
% NaCl, but not above
45
°C or above
12
% NaCl. The optimum growth pH, temperature and NaCl are 7.0–8.0,
28
°C and
5
% NaCl. Resistant to rifampicin, amikacin, carbenicillin, tobramycin, kanamycin, clarithromycin and penicillin G (each at
30
µg), but sensitive to gentamicin, novobiocin, streptomycin, doxycycline, acetylspiramycin, carbenicillin, midecamycin, minocycline, cephalothin and chloramphenicol. (+)-D-Fructose, (+)-D-galactose, (+)-cellobiose,
myo
-inositol, (+)-L-rhamnose salicin, (+)-maltose, (+)-D-mannitol and (+)-trehalose are utilized as carbon sources, but sorbitol, (+)-D-lactose, dextrin, arabinose, (+)-raffinose and (‾)-sucrose are not. Decomposes gelatin, hypoxanthine, xanthine, allantoin and starch, but not L-tyrosine or casein. Cell-wall hydrolysates contain
meso
-diaminopimelic acid, arabinose and galactose. MK-

(
H

) (
79
%) is the predominant menaquinone; MK-

) (
13
%) is also present. The phospholipids comprise diphosphatidylglycerol, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylglycerol and phosphatidylinositol mannoside. The major cellular fatty acids are iso-C
16
: 0 and iso-C
