In the present study, all of the strains have shown extracellular multi enzyme
activity. However, majority of isolates were amylase (82%) and esterase (74%) producers
while 66% of the isolates showed lipase and β-galactosidase production (Fig. 1).
Percentage of cellulase producing isolates was less (50%) as compared to other enzymes.
Low count of cellulase producers is most likely due to the low content of organic matter
in the hotspring water (Kazue et al., 2006). The production of extracellular lipases and
esterases by Bacillus sp. was reported by Jung et al., (2003) while Batra et al., (2002)
reported the production of β-galactosidase by Bacillus sp. isolated from hotspring.
