TABLE 1.
Cell mass variation and reducing sugars and enzymes produced after 30 days of cultivation of L. gongylophorus CCT1 on polysaccharides
| Carbon source | Cell mass variation [mean (SD)]a | Reducing sugar production (mg) [mean (SD)]a | Enzyme activityb (μmol/g/h) [mean (SD)]a |
|---|---|---|---|
| Xylan | 1.8 (0.13)1 | 47 (5.8)1,2 | 190 (56)1 |
| Starch | 1.7 (0.15)1 | 44 (26)1,2 | 620 (250)1 |
| Pectin | 1.3 (0.25)1,2 | 190 (25)1 | 4,600 (1,100)2 |
| Cellulose | 1.0 (0.06)2 | NDc | ND |
| Acid-swollen cellulose | 1.1 (0.28)2 | ND | ND |
| Microcrystalline cellulose | 1.0 (0.13)2 | 1.4 (1.1)2d | 23 (5.7)1d |
| Carboxymethylcellulose | 1.1 (0.11)2 | 29 (3.0)2d | 120 (90)1d |
| None | 0.65 (0.10) |
a
Values followed by distinct numbers are significantly different from each other (Dunn’s test).
b
Enzyme activities assayed were xylanase after growth on xylan, amylase after growth on starch, pectinase after growth on pectin, CMCase after growth on carboxymethylcellulose, and cellulase after growth on acid-swollen cellulose or microcrystalline cellulose.
c
ND, not detected.
d
Detected in 60-day cultures but not in 30-day cultures.
