I can ferment glucose and can growin anaerobic environment via fermentation of this sugar. I alsoproduce purple color in a microbiological test to which oil isadded to stimulate the formation of anaerobic environment.

1. What is the substrate of the enzyme, the presence or absence ofwhich will determine whether the test, with the purple color, willbe positive or negative

a)glucose           b) aminoacid(s)              c)protein                     d) lipids

1. What is the indicator of the test media from question 13.

a) amylase    b) methyl green   c) ferric ammonium citrate    d) bromcresolpurple     e) iron

1. What is the nature of the chemical reaction catalyzed by thisenzyme?

a) hydrolysis ofnucleotides                                  b) hydrolysis of proteins

c) decarboxylation of aminoacids                       d) deamination of amino acids

I can not grow in a viscousenvironment. I don’t have DNAse.

1. What will be the color of the growth around me, if I lack theseskills?

a)colorless       b)green             c)red                     d) black

1. I can remove amine groups from amino acids such asphenylalanine. What will be the color associated with my growthafter the addition of the appropriate indicator?

a)colorless               b)green              c)red                          d) black

1. I am a test where no indicator is needed. I am whitish in colorto begin with and when bacteria that grows on me makes the rightenzyme, you could see a halo around its growth. What is myname?

a) lipasetest                b) Glucoronatetest                c) amylasetest                        d) casease test
