Algae: Phototrophic eukaryotic microorganisms Fungi: Nonphotosynthetic eukaryotic microorganisms that contain rigid cell walls Slime molds: nonphototrophic eukaryotic microorganisms that lack cell walls and that aggregate to form fruiting structures (cellular slime molds) or masses of protoplasm (acellular slime molds) Protozoa: unicellular eukaryotic microorganisms

Chapter 6 Viruses 6.1 General Properties of Viruses 6.2 Structure of viruses 6.3 The cultivation of viruses 6.4 General Features of Virus Reproduction 6.5 one-step growth curve 6.6 Temperate Bacteriophages: Lysogeny and Lambda

Pili and fimbriae G short, fine, hairlike appendages that are not involved in motility Fimbriae/fimbria: 1000piece/cell, adhesion to host epithelium Sex pill/pilus: 1-10piece/celly sexual conjugation, they are genetically determined by sex factors or conjugative plasmids and are required for bacterial mating Receptors of some bacterial viruses

Oxidative phosphorylation occurs at cell membrane since there are no mitochondria) Cell wall Cytoplasm Cell membrane The cell wall is outside of cell membrane -rigid, protecting cell from osmotic lysis

Isolation of pure cultures the growth curve Measurement of microbial growth The continuous culture of microorganisms
