Chapter 19, Problem 20P

Summary Introduction

To explain: The advantages of using mutant lacking Cytochrome oxidase instead of wild-type yeast for large-scale production of ethanol.

Introduction:

Respiration-deficient mutants are formed from wild-type parents by using mutagenic agents. Cytochrome oxidase is not present in mutants and one of the effects of mutation is that fermentation is not suppressed by oxygen.

Summary Introduction

To explain:

The reason behind the elimination of Pasteur effect in absence of Cytochrome oxidase.

Introduction:

Louis Pasteur observed that when oxygen is added to anaerobic cells consuming high amount of glucose, rate of glucose consumption declines. Along with the decline in consumption of glucose, accumulation of lactate ceases.
