Characteristics of Microbes

What are the 8 visible colony characteristics?
Shape, margin, elevation, size, texture, appearance, pigmentation, optical property
What are the 6 types of culture media?

Defined (What a bacteria needs)

Complex (nutrition for multiple types)

Selective (allows for 1 trait to thrive)

Differential (Selective and color changes by characteristic)

Anaerobic

Transport

What is the Generation Time Curve?

Lag phase (Cell prep for division)

Log phase (Log growth/division)

Stationary phase (growth and death in balance)

Death

Nt = (N0)(2^n)

Nt = # of cells in the population at time T

N0 = original # of cells

n = The # of divisions

What are the 6 types of enzymes?

Oxidoreductase

Transferase

Hydrolace

Lyase

Isomerase

Ligase

What are the 3 energy periods of Glycolysis?

Energy Investment (2 ATP used)

Lysis (NAD and P groups)

Energy conservation (2 ATP generated)

Colony Forming Units per Ml equation
CFU/ML * dilution factor = cfu/ml
Solid sample colony forming units per ml (2nd equation for solids only)
CFU/ml*volume water/grams of sample
Solve Nt = N0*2^n

x=2^n

Log(x)=Log(2^n)

Log(x)=nLog(2)

Log(x)/Log(2) = N

What are the 7 types of fermentation?

Lactic Acid

Alcoholic Acid

Proprionic Acid

Mixed Acid

Butandeiol Fermentation

Butenol/Acetone

Amino Acid Fermentation
