Fig. 2From: Identification of a new thermostable and alkali-tolerant α-carbonic anhydrase from Lactobacillus delbrueckii as a biocatalyst for CO2 biomineralizationThe stability of pH on activity of purified LdCA. The assay was carried out at 0 °C with CO2 as a substrate, using 25 mM of different buffers for incubation: sodium citrate (circle); sodium phosphate (diamond); glycine–NaOH (triangle). The enzyme activity measured without any treatment was taken as 100 %Back to article page
