Aerobic growth properties of CS mutants^a

Carbon source	Growthb of strain:
	104A14	CSDX1	CSDX426	A39S	A39L
Mannitol	++	++	++	++	++

^aGrowth was tested on minimal salts agar medium supplemented with 0.0125% arabinose and containing 0.4% of the indicated carbon source. Plates were incubated aerobically at 30°C for 6 days. The medium pH was 7.4. 

^b++, growth similar to that of 104A14 on the carbon source (growth on mannitol, fructose, xylose, sorbitol, glycerol, and glutamate was similar for all five strains); +, growth notably poorer than that of 104A14; ±, visible but very poor growth; −, no growth.
