The modified forms of starch have varied applications in food and other industries. Basic strategies to modify starch quality are 

(i) genetic modification of crops (by breeding or biotechnology)

(ii) food processing (using enzymes and chemicals)

(iii) food supplementation (modification of starch by employing microorganisms)

Some classes of mutants were obtained from the parental strain as the source of genetic material for transduction:

I) A strain that are resistance to thialysine

II) A strain in which both the threonine-regulated AK and HD were resistant to feedback inhibition by threonine

III) A strain is selected for ß-hydroxynorvaline Sensitive, in which HDI was sensitive to both inhibition and repression and the threonine-regulated AK was constitutively synthesized

L-Cysteine has traditionally been obtained by extracting it from acid hydrolysates of human hair and animal feathers. High levels cannot be synthesized from glucose because l-cysteine feedback inhibits the enzyme, which catalyzes one of the steps in the biosynthesis of l-cysteine. These enzyme are,
