others anaerobic May be free living, parasitic, or symbiotic, 69 Enteric Bacteria Gram negative Can live in aerobic & anaerobic habitats Includes E. coli in intestines Salmonella – causes food poisoning, 70 Chemoautotrophs Gram negative Obtain energy from minerals like iron Found in freshwater ponds, 71 Nutrition, Respiration, and Reproduction, 72 Modes of Nutrition Saprobes – feed on dead organic matter Parasites – feed on a host cell Photoautotroph – use sunlight to make food Chemoautotroph – oxidize inorganic matter such as iron or sulfur to make food, 73 Methods of Respiration Obligate Aerobes – require O2 (tuberculosis bacteria) Obligate Anaerobes – die if O2 is present (tetanus) Facultative Anaerobes – don’t need O2, but aren’t killed by it (E. coli), 74 Bacterial Respiration Anaerobes carry on fermentation Aerobes carry on cellular respiration, 75 Reproduction Bacteria reproduce asexually by binary fission Single chromosome replicates & then cell divides Rapid All new cells identical (clones), 76 Cellular organism copies it’s genetic information then splits into two identical daughter cells, 78 Reproduction Bacteria reproduce sexually by Conjugation Form a tube between 2 bacteria to exchange genetic material Held together by pili New cells NOT identical, 80 Spore Formation Form endospore whenever when habitat conditions become harsh (little food) Able to survive for long periods of time as endosperm Difficult to destroy (heat resistant), 81 Transduction & Transformation Genetically change bacteria May become antibiotic resistant Transformed bacteria pick up pieces of DNA from dead bacterial cells Transduction – viruses carry foreign DNA to bacteria; used to make insulin, 83 Pathogens Called germs or microbes Cause disease May produce poisons or toxins Endotoxins released after bacteria die (E. coli) Exotoxins released by Gram + bacteria (C. tetani).

Inactive member won’t be able to Types of Bacteria on the Basis of Shape: Cocci: This classification is done on the basis of shape, cell wall, flagella, nutrition and morphology. Not just finding your interest, but facilitate you broadcast your interest. 1.5 1.5 BACTERIAL STRUCTURE The outer layer or cell envelope consists of two components, a rigid cell wall and beneath it a cytoplasmic or plasma membrane. Learning Objectives. Facultative anaerobes: Those bacteria that do not require O2 but can use it if available. 3. Bergey’s Manual of Systematic Bacteriology. Appendages 5. library of professional ppt presentations.
