When microorganisms encounter nutrient starvation conditions, they respond to them by arresting all metabolic activity and growth. then carry out starvation-induced activities such as production of enzymes. This includes many enzymes such as proteases, lipases, and capturing enzymes such as glutamine synthetase, and alkaline phosphatase (Kjelleberg and others 1987; Matin and others Siegle and Kolter 1992). During starvation, many bacterial species show increased resistance to a number of environmental stresses such as low pH and heat and oxidative stress (Hartke and others 1994: Watson and others 1998).
