aerobes

vibrio, aliivibrio, and photobacterium are facultative _______

aerobes

_____ uses a reversal in the citric acid cycle

autotrophy

an example of a predatory bacteria is

bdellovibrio

luciferase is involved in the light production of ______ bacteria

bioluminescent

another colored species of green sulfur bacteria that exists is

brown

all species of cyanobacteria fix carbon dioxide by the

calvin cycle

magnetospirillum are _____ and _____

chemoorganotroph, microaerophile

myxobacteria are _____ soil bacteria

chemoorganotrophic

what are the 2 pigments that cyanobacteria produce

chlorophyll a and phycobilins

green sulfur bacteria have _____ that are bacteriochlorophyll-rich bodies bounded by a thin membrane

chlorosomes

have type I and type II photosystems

cyanobacteria

the only group of oxygenic phototrophic bacteria are the

cyanobacteria

vibrio, aliivibrio, and photobacterium have a _____ metabolism

fermentative

_____ myxobacteria exhibit complex behavioral patterns and life cycles

fruiting

myxobacteria display swarming behavior and form ________ that produce myxospores

fruiting bodies

functional traits can be shared between organisms with divergent SSU rRNA sequences because

functional traits may evolve independently, be shared through horizontal gene transfer, or be lost in divergent lineages

phylogenetically distinct, nonmotile, anoxygenic phototrophs

green sulfur bacteria

green sulfur bacteria are often found at the greatest depths of all phototrophic cells in lakes, oceans and microbial mats, this is because green sulfur bacteria are

have chlorosomes that are very efficient at harvesting light allowing them to perform photosynthesis where light intensities are very low

green sulfur bacteria use ____ as an electron donor and oxidize it to ____

hydrogen sulfide, sulfate

some bioluminescent bacteria are capable of ____ production

light

are magnetotactic, demonstrating directed movement in a magnetic field

magnetospirillum

most bioluminescent bacteria inhabit _____ environments

marine

bdellovibrio are widespread in _______, including marine environments

soil and water

myxobacteria display ________ behavior and form fruiting bodies that produce myxospores

swarming

all cyanobacteria species have specialized membranes called

thylakoids

the pathogen that causes cholera

vibrio

3 types of bioluminescent bacteria

vibrio, aliivibrio, and photobacterium

bioluminescent bacterial cells are motile, straight or curved ____

rods

group of gliding bacteria that form multicellular structures called fruiting bodies and show complex developmental life cycles

myxobacteria

obtain nutrients by lysing other bacteria and utilizing released nutrients

myxobacteria

reflecting the complex life cycle, their genome is much larger than other bacteria such as E. coli

myxobacteria

their lifestyle includes consumption of dead organic matter or other bacterial cells

myxobacteria

under appropriate conditions, vegetative cells aggregate, construct fruiting bodies, and undergo differentiation into

myxospores

many species of cyanobacteria also fix

nitrogen

vegetative myxobacterial cells are simple, _______ that glide across surfaces

nonflagellated rods

luciferase is an ____ dependent enzyme

oxygen

some bioluminescent bacteria are

pathogenic

bdellovibrio have two stages of

penetration

cyanobacteria cell walls contain

peptidoglycan

bdellovibrio species are predatory cells that replicate in the

periplasmic space

bdellovibrio species replicate in the ____ of ____ bacteria

periplasmic space, gram-negative

bacterial bioluminescence regulation is mediated by population density or

quorum sensing
