The Arginine Deiminase Pathway In Lactococci: Physiological Role And Molecular Characterization, Lan-Szu Chou

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lactococcus is an economically important group in lactic acid bacteria (LAB) that are often used in the dairy industry as starters for cheese production. Good starter strains should possess the ability to grow, ferment milk sugar, and produce desirable flavor compounds during cheese making. Therefore, it is essential to understand the physiology of these starters during cheese processing in order to obtain high-quality cheese products.

Cheese manufacturing compromises several stress factors that affect the growth of starter lactococci. Among these stressed environmental parameters, sugar starvation is the most important one to overcome to obtain energy for cellular processes. It is …
