Chapter 6 Microbial Growth 1 Growth • increase in cellular constituents that may result in: – increase in cell number • e.g.‚ when microorganisms reproduce by budding or binary fission – increase in cell size • e.g.‚ coenocytic microorganisms have nuclear divisions that are not accompanied by cell divisions • microbiologists usually study population growth rather than growth of individual cells 2 The Growth Curve • observed when microorganisms are cultivated in batch

World War II brought death and destruction upon the world. On the other hand‚ it also opened doors for pioneering developments that commonly occur during such situations of high adversity. Some of the most important advancements took place in the field of medicine when the world was embroiled in World War II. As Dr. Ralph Major states‚ "An army is a vast laboratory of medical research where disease and injuries are seen on a far larger scale than in peacetime. Many improvements in the treatment of
