bacterial nutrition Flashcards
autotrophic
organisms which make their own food
heterotrophic
organisms which take in food made by other organisms
A
photosynthetic bacteria
use light energy to make food
H
parasitic bacteria
take food from live host
some cause diseases
heterotrophic
take in food
autrophic
make food
saprophytic
eg. bacteria of decay
photosynthetic molecules
eg, purple sulphur bacteria
parasitic
eg, streptococcii
chemosynthetic
eg, nitrifying bacteria
factors that affect the growth of bacteria 🦠
temperature
ph
oxygen concentration
scale
lag log stationary death
lag1
🦠 no. low as they are adapting to new enevironmenta
log2
bacteria are producing at maximum rate due to ideal conditions
food storage oxygen
stationary3
no. produced=no.dying
due to lack of space and food
death4
bacteria start dying more than being produced
bioprocessing
the use of micro-organisms to form a useful product
bioreactor is
a container in which microorganisms are used to produce a product
