Meaning they do not have a membrane-bound
organells
All members of Monera
are prokaryotes
Capsule is a dry layer and acts as an
extra layer of protection
Cell wall protects and prevents the cell
from expanding and bursting
Flagellum allows the cell to move
or swim
Cell membrane retains the cell contents
and controls what passes in and out of
cell
Plasmid is a small loop of DNA that contains
genes (which may cintrol antibiotic
resistance)
DNA contains genes that control
the cell
DOES NOT HAVE A
NUCLEUS
Structure of Bacteria
Spherical-shaped
Spiral-shaped
Rod-shaped
Types of
Bacteria
Cell division occurs when the cell membrane and cell
wall pinch in
The two identical loops of DNA move to opposite ends
of the cell
The cell increases
in size
The loop of DNA replicates
Binary
Fission
Bacterial Reproduction
An endospore is a thick and tough-walled dormant and
dehydrated bacterial cell formed during unsuitable conditions
Outer coat forms around the
cortex
A thick wall (cortex) forms around
enflufed cell
The smaller cell is engulfed by
larger cell
Cell undergoes asymmetrical binary fission
(one cell is larger than the other)
Conditions become unfavourable for
bacterium
Process of endospore
formation
Endospore formation
make food by converting one chemical
into another
Chemosynthesis
make food using light
energy
Photosynthesis
Autotrophic nutrition is where
the bacteria produce their
own food
live on and take in food from dead
sources
Saprophytic
take in food from a live host and
usually harms the host
Parasitic
Heterotrophic nutrition is where
bacteria obtain their food and
nutrients from other living
organisms
Nutrition in Bacteria
Only a measured amount of nutrients are
added
Bacteria act on substrate and experiences lag,log and
stationary phases
Generally product is removed before
decline phase
It's a simple
process
It allows small volumes of products
to form
The micro-organisms grow
naturally
Advantages
Bioreactor is sterilised and process
starts again
Product is separated from
micro-organisms
Batch
Processing
Nutrients are constantly added to the bioreactor
at the same rate at which the product is withdrawn
Micro-organisms are kept at the log phase
of growth
Product is constantly removed from the
bioreactor
No time is
wasted
No need to sterilise bioreactor
so often
Product formed more
rapidly
Advantages
Bioreactor is left open for inflow of nutrients and outflow
of product
Continuous -flow
Processing
Food Processing
are chemicals produced by
micro-organisms that kill or
prevent the growth of other
micro-organisms
No effect on
viruses
This one resistant bacterium is then able
to multiply
When one bacterium develops a
mutation that enables it to avoid effects
of an antibiotic
Antibiotic Resistance
Overuse of
Antibiotics
Antibiotics
