which is gram positive and which is gram negative?

Purple:

Gram + have thick peptidoglycan layer which acts like a sponge holding the crystal violet complex. Lack lipopolysaccharide outer membrane.

Pink:

Gram – have thin peptidoglycan layer surrounded by lipopolysaccharide (fatty starch) outer membrane that disrupts crystal violet colorization process. Stains pink with Safranin.

what does clear halo mean, what does dark purple mean

Clear halo = bacteria that produce amylase

Dark purple = starch present, no amylase

nitrogen fixing bacteria lives in root nodules of plants

n2—> nh3

what shape of bacteria is this

bacillus (rod)

what shape of bacteria is this

spirrilus

what shape of bacteria is this

cocci

Cyanobacteria Oscillatoria sp.

cyanobacteria not true algau

prokaryote

name and what is the arrow pointing at

Cyanobacteria Anabaena sp.

arrow pointing at heterocysts, fix bacteria

cyanobacteria not true algaea

what is this representing

colony morphologies

describe archaea and name types

Prokaryotic cells -

Similar to Bacteria, but differences in DNA and cell walls

Extremophiles! -

Thermophiles: Inhabit extremes of temperatures -Halophiles: Inhabit extremely salty areas -Methanogens: Thrive in methane producing places

what type of test describe

disk diffusion test

Compare various petri dishes with colonies of bacteria in them to find out which antiseptic is most useful in killing bacteria. Use metric system!

what is an antiseptic? - Substance that prevents the growth of disease-causing microorganisms - The larger the halo, the better that antiseptic is at inhibiting growth of that particular microorganism
