BIOCALCIFICATION OF CONCRETE USING CARBONIC ANYHDRASE PRODUCED BY SOIL BACTERIAL ISOLATES
ABSTRACT Two (2) bacterial isolates obtained from Garima construction sites were named GARIMA (A) and (B), and code-named GA (A) and GA (B) respectively. They were screened for their carbonic anhydrase (CA) producing ability. Isolates GA (A) and GA (B) showed positive reaction to para-nitrophenylacetate (pNPA), producing yellow and peach/orange coloured colonies respectively. The isolates were used to produce the crude CA and the mean enzyme activity with standard error ...
