Proper Attire
Closed-toe shoes, Long hair needs to be pulled back, Avoid loose-fitting items of clothing
and loose jewelry or loose sleeves, long pants, Goggles or approve eyewear, Lab coats stored
in the lab and not to be removed from the lab.
Types of Wastes in Microbiology
- Glass- Paper- Biological
Major Classes of Microorganisms
Virus• Algae• Fungi• Protozoa• Bacteria
which microorganisms are Prokaryotes
Bacteria
which microorganisms are Eukaryotes
Algae, Fungi, Protozoa
Neither prokaryotic or eukaryotic
Virus
Prokaryotes
no nucleus, only nucleoid, no internal membrane bound organelles, has cell membrane,
smaller ribosomes, reproduction via binary fission, one chromosome, smaller cells
Eukaryotes
,has nucleus, has internal membrane bound organelles, has cell membrane, bigger ribosomes,
mitosis and meiosis, mrore than one chromosome, larger cells
viruses
noncellular, require a host cell for replication, 15-450 nm, HIV, Herpes, Hepatitis, flu
algae
unicellular or multicellular, in fresh and ocean water, variable size, photosynthetic
protozoa
single-celled eukaryotes, 10 mu m diameter, typically in water, some in animal hosts, most
asexual, some sexual, most capable of locomotion w/ pseudopodia, cilia, flagella, disease-
causing agents
pseudopodia
false feet, extenstion of the internal guts of a cell
cilia
hairlike projections for movement
flagella
long filament like tail for swimming
fungi
eukaryotic w/ membrane bound organelles, some single cell, common agent of human
disease, obtain food from other organisms, cell wall, molds & yeasts
mold
multicellular, have hyphae, reproduce via sexual and asexual spores
, yeasts
unicellular, reproduce asexually by budding
bacteria
prokaryotic, diverse environments, chemical/light energy source, 0.5-10 mu m, mostly single
cell, shape, cell wall type, and motility determine genus and species
bacterial shapes/morphology
rods/bacillus, coccus, spirillum/curved
nucleic acids
heredity and DNA/RNA
proteins
structure & function, amino acids
carbohydrates
OSE endings, glucose, lactose, energy
lipids
barrier from outside, fatty acids, phospholipid bilayer
bacterial cell structure
nucleoid->ribosomes in cytoplasm->cell membrane->cell wall->periplasm(Gram- only)->out
membrane(Gram- only)->capsule(sometimes)->flagella
nucleoid
heredity (single, circular DNA chromosome)
