Because the EARLY DAYS OF MICROBIOLOGY it's been recognized THAT, in the course of their lifestyles cycles, microorganisms show developmental adjustments in universal with different organisms. within the final decade curiosity during this element of microbiology has constructed enormously, and learn findings have supplied an figuring out of the genetic, molecular and biochemical bases of improvement.

C. allowing only one half-reaction to occur. d. only under aerobic conditions. Short Answer 5. Consider bacterium A that oxidizes hydrogen as a source of energy and uses reduction of nitrate to nitrite as the other half-reaction. 2 lor these half-reactions). Which bacterium can obtain more energy from the oxidation of an equivalent amount of hydrogen? 6. Bacteria can obtain energy by the oxidation of chemicals. Using the Gibb's free energy change for an oxidation/reduction (redox) reaction, discuss what variables determine the amount of energy available from a redox reaction.

What are unit membranes and why are they selectively permeable? • What structures are inside and outside the bacterial cell? / What are the diffirent baclerial shapes? / What are gram-negative and gram-positive bacleria? / What is peptidoglycan? / I1 l hal are Ihe properties andjiu"tions if bacterial slructures? , spirochete), filamentous, and appendaged. Bacterial shape is primarily determined by cell wall structure and is one of the properties used to identify and classify bacteria. All bacteria have a cell wall with the exception of the mycoplasma group of bacteria (consisting of six genera), the most common being the genera Mycoplasma and Ureaplasma.

Weighing bacteria requires a large number of bacteria for accuracy (the wet weight of a bacterium is about 10- 12 g). The most widely used and practical technique for measuring the number of bacteria in suspension is measuring turbidity. Turbidity refers to the cloudiness of a solution. Light scattering is the primary process by which turbidity occurs. A good approximation is that the bactcrial weight concentration is directly proportional to the amount of light scattering. Absorbance meters ("colorimeter") and spectrophotometers can be used to measure turbidity.
