Time-dependent heat inactivation of lipase LipA. Purified lipase LipA (18 ng/ml) from P. aeruginosa was incubated at 70°C in the absence (−○-) and in the presence of 1 mg/ml (−■-) bacterial alginate from P. aeruginosa SG81 shown in red, (−--) deacetylated bacterial alginate from P. aeruginosa SG81 shown in red, (−♦-) bacterial alginate from P. aeruginosa FRD1 shown in orange, (−◊-) bacterial alginate from P. aeruginosa FRD1153 shown in orange, (−□-) algal alginate shown in pink, (−▲-) xanthan shown in green and (−●-) dextran shown in blue. Results are shown as mean of five independent experiments with standard deviations.
