Phylum Firmicutes, Class Bacilli, Order Bacillales, Family Staphylococcaceae, Genus Salinicoccus, Salinicoccus siamensis Pakdeeto
et al. 2007.
Gram-positive cocci, 0.6-0.8 μm in diameter, occuring singly, in pairs, tetrads or
clumps. Non-motile. Non-spore-forming.
Colonies are smooth, circular, of low convexity and orange in colour. Strictly aerobic.
Moderately halophilic; growth occurs in media containing 1.5-25% NaCl; optimum
10% NaCl. Grows in pH 6.0-9.0; optimum pH 8.5. Growth temperature range 15-45
ºC, optimum 37 ºC.
Isolated from a traditional fermented shrimp paste (‘ka-pi’) produced in Thailand.
Positive results for catalase, oxidase, acid production from: D-fructose, D-glucose,
glycerol, D-ribose & trehalose.
Negative results for aesculin hydrolysis, arginine hydrolysis, casein hydrolysis, citrate utilization, gelatin hydrolysis, indole production,
methyl red test, nitrates reduction, starch hydrolysis, Tween 80 hydrolysis, urease, Voges–Proskauer test, acid production from:
amygdalin, L-arabinose, cellobiose, aesculin, D-galactose, gluconate, myo-inositol, inulin, lactose, maltose, D-mannitol, D-mannose,
melibiose, melezitose, methyl alpha-D-glucoside, raffinose, L-rhamnose, salicin, sorbitol, sucrose & D-xylose.
