Fig. 1From: Bacillus aryabhattai TFG5-mediated synthesis of humic substances from coir pith wastesTime course production of tyrosinase and laccase by B. aryabhattai TFG5. Enzyme activities were estimated at 4-h intervals in the respective media, and the optical density of 600 nm measured for the growth of B. aryabhattai TFG5. Values are the means of three replicates, and the error bar indicates the standard deviationBack to article page
