Tetracycline

Introduction

Tetracycline is used in industrial sugar and ethanol fermentation (specifically molasses) as an antibiotic to control bacterial contamination, particularly lactic acid bacteria, which compete with yeast

Tetracycline is used in distilleries and sugar-based fermentation to:

• Control bacterial contamination (mainly Lactobacillus)

• Protect yeast performance

• Improve ethanol yield

• Reduce acid formation (lactic/acetic acid)

Where It Is Used

• Molasses-based ethanol plants

• Grain-based distilleries

• Sugar fermentation units

Benefits

• Maintains yeast viability

• Increases fermentation efficiency

• Reduces sugar loss

• Improves alcohol recovery %
