Table 1 Percentage of resting cells formed after stress exposure

From: Formation and characterization of non-growth states in Clostridium thermocellum: spores and L-forms

Stress type Specific modification Percent spores Percent L-forms
MTC media (control) No modifications 0 0
Nutrient limitation Reduced cellulose (1g L-1) 0 0
Nutrient limitation Low phosphorous 0 0
Nutrient limitation Low nitrogen 0 0
Nutrient limitation No vitamins 4.2 ± 2.8 0
Inhibitor Added ethanol 0 0
Inhibitor Added acetate 0 0
Oxidative stress Added oxygen 6.6 ± 4.0 0
Substrate change Transfer from cellulose to cellobiose 6.9 ± 3.7 0
Substrate changes Transfer from cellobiose to cellulose 6.2 ± 3.7 0
Starvation Depletion of substrate during steady state growth 0 98.0 ± 0.017
  1. Conditions predicted to be unfavorable for growth were tested to determine which stressors cause C. thermocellum to form spores or L-forms. The percentage of resting cells to total cells is shown. Error represents one standard deviation, n = 3.
