identified as B. amyloliquefaciens according to phenotypic tests
and was confirmed by 16S rRNA gene sequencing. The present
work has been taken up with a view of exploring the possibilities
of using agro-industrial residues as a starch substrate for
the production of amylases by the tested strain in submerged
fermentation, which can hydrolyze starch to glucose. The use
of inexpensive substrates can economize the process of production.
This strain was capable to produce the highest a and b
amylases after 30 h as well as c amylase after 36 h in the medium
containing 2% potato starch waste, respectively incubated
at 50 C using shake flasks (150 rpm) as a batch culture
