| Jeongeupia chitinilytica |
Colonies on TSA after 48h incubation at 25 ºC, are dark-yellow-pigmented, convex,
round and smooth, with entire edges, 1-2 mm in diameter. Growth occurs at 20-37
ºC, optimally at 25-30 ºC. Can grow in pH 6.0-8.0, optimally in pH 7.0-8.0. Can grow in
0-2% (w/v) NaCl, optimally in 1-2% NaCl.
