Biosynthesis of Extracellular Polymeric Substances by the Marine Bacterium Saccharophagus degradans under Different Nutritional Conditions

Table 1

Chemical composition of the culture mediums used: basal medium (BM) and nutrients limited medium (NL).

Compound (g/L)	Basal medium (BM)	Limited medium (LM)
Glucose	10	10
NH4Cl	6.68	3.34
KH2PO4	2.8	1.4
NaCl	23	23
KCl	1.5	0.75
CaCl2	0.3	0.15
MgSO4	0.6	0.30
FeSO4	0.16	0.08
EDTA	0.15	0.08
Tris-HCl (mL/L)	100	100

For experiment A the carbon sources used were also galactose, sucrose, starch, xylose, or fructose.
Limitation consisted in reducing by 50% the amount of N, P, K, Ca, Mg, and Fe originally present in BM.
pH 7.6.
