Pektinase dapat diproduksi dari berbagai macam mikroorganisme seperti Aspergillus niger dan Bacillus firmus. Pectinase can be produced from various kinds of microorganisms such as Aspergillus niger and Bacillus firmus. This research aim was to investigate the influence of the addition of Ca ion towards the pectinase activity from Bacillus firmus and to determine the kinetic parameters. Pectinase was in the form of a crude extract.

Asih, Sri. North Tapanuli has a soda fountain as a source of potential biotic diversity of Indonesia, one of which is the hydrolytic bacteria. The purpose of this study was to isolate bacteria from the soda fountain and test Parbubu hidrolasenya enzyme activities, ie lipase, protease, and cellulase enzyme hidrolase and characterize the best in certain conditions of temperature and pH. Isolation of bacteria from the soda fountain Parbubu using pour plate method produced 23 isolates of bacteria.
Test semikualitatif hidrolase enzyme using hydrolytic enzymes in media index showed that the bacterial isolates P9 has the highest lipase activity. Harvest time P9 bacterial lipase based on the growth curve and enzyme production curves, ie on the seventh hour of incubation. Lipase enzyme has optimum activity at pH 7, at 5.
