TRUE

FALSE

In the production of bioethanol from starch by yeasts, amilases...

A. are not necessary to hydrolize starch because yeasts can perform starch saccharification.

B. are necessary to hydrolize starch because yeasts do not have these enzymes

C. are never added because they do not resist at the high temeperature reached during the fermentation.

D. are necessary to hydrolize cellulose because yeasts do not have these enzymes

What is bioventing?...

a. It is an ex situ remediation technology that stimulates the natural biodegradation of contaminants in soil

b. It is a remediation technology that stimulates the natural in situ biodegradation of contaminants in soil by adding new microorganisms with targeted degradation capabilities.

c. It is an in situ remediation technology that stimulates the natural in situ biodegradation of contaminants in soil by providing air or oxygen to existing soil microorganisms.
