25
supply only the bare necessities for survival and can be useful in manipulating which pathways are turned on in the bacterium.
Minimal media
26
all the ingredients are known
Defined media
27
tend to contain complex mixtures of nutrients and chemical species in unknown proportions, such as yeast extract.
Undefined media
28
A culture medium is simply water and nutrients that support microbial growth.
Bacterial culture methods
29
3 primary categories of culture media
NUTRITIVE DIFFERENTIAL SELECTIVE
30
Media that support the growth of many different microorganisms without distinguishing genera or species
NUTRITIVE
31
allow several different types of bacteria to grow, but also contain compounds that allow microbial genera
DIFFERENTIAL
32
are used to select for the growth of a particular "selected" microorganism.
SELECTIVE
33
Bacterial culture methods (3)
Culture broth Storing bacterial cells Nutrient agar
34
Culture in liquid media, also known as a BLANK, gives the bacteria present easy access to the available nutrients compared to static bacterial colonies.
Culture broth
35
When looking to store bacterial strains long term, they may be grown up in liquid media. Glycerol is then added, which will prevent complete freezing and consequent lysis of the bacterial cells, permitting their storage at
-80 °C.
36
Adding agar to BLANK enables it to be set in petri dishes, as slopes or in plugs.
liquid media
37
is useful when you wish to select individual colonies from a mixed culture
Solid media
38
Common problems with bacterial culture (5)
Contamination Overgrowth of some species Antibiotic treatment prior to sampling Incorrect growth conditions Non-culturable and slow-growing organisms
39
Good aseptic technique can help to avoid contamination of bacterial cultures.
Contamination
40
Some bacterial species grow easily and vigorously
Overgrowth of some species
41
In a diagnostic setting, it is important to know if antibiotic treatment has been administered prior to sampling.
Antibiotic treatment prior to sampling
42
The use of inappropriate or suboptimal growth conditions may impede or completely prevent the growth of your target strain.
Incorrect growth conditions
43
Some bacterial species, even now, cannot be grown in the lab.
Non-culturable and slow-growing organisms
44
Applications of bacterial culture (5)
Diagnose infection Genetic manipulation Epidemiological study Scale up to enable omics studies Develop vaccines and therapeutics
45
cells are grown under BLANK, generally outside their natural environment
controlled conditions
46
macroscopically visible collection of millions of bacteria originating from a single bacterial cell
Colony

introduced this medium Used for preparing solid medium obtained from seaweeds

Types of Culture media Based on their consistency (3)
solid medium liquid medium semi solid medium
49
Types of Culture media Based on the constituents ingredients (4)
simple medium complex medium synthetic or defined medium Special media
50
special media (8)
◦Enriched media ◦Enrichment media ◦Selective media ◦Indicator media ◦Differential media ◦Sugar media ◦Transport media ◦Media for biochemical reactions
51
Based on Oxygen requirement (2)
Aerobic media Anaerobic media
52
contains 2% agar Colony morphology, pigmentation, hemolysis can be appreciated.
Solid media
53
no agar. For inoculum preparation, Blood culture, for the isolation of pathogens from a mixture. Eg: Nutrient broth
Liquid media
54
0.5% agar. Eg: Motility medium
Semi solid medium
55
Media other than basal media. They have added ingredients. Provide special nutrients
Complex media
56
Media prepared from pure chemical substances and its exact composition is known
Synthetic or defined media
57
Substances like blood, serum, egg are added to the basal medium
Enriched media
58
Used to grow bacteria that are exacting in their nutritional n
Enriched media
59
Liquid media used to isolate pathogens from a mixed culture.
Enrichment media
60
is incorporated with inhibitory substances to suppress the unwanted organism.
Media
61
These media contain an indicator which changes its colour when a bacterium grows in the
Indicator media
62
Media used for transporting the samples.
Transport media
63
These media are used to grow anaerobic organisms.
Anaerobic media
64
Culture methods include: (7)
Streak culture Lawn culture Stroke culture Stab culture Pour plate Method Liquid culture Anaerobic culture methods
65
Used for the isolation of bacteria in pure culture from clinical specimens.
STREAK CULTURE
66
Provides a uniform surface growth of the bacterium.
LAWN CULTUR
67
e is made in tubes containing agar slope / slant.
STROKE CULTURE
68
Provide a pure growth of bacterium for slide agglutination and other diagnostic tests.
STROKE CULTURE
69
Prepared by puncturing a suitable medium – gelatin or glucose agar with a long, straight, charged wire
STAB CULTURE
70
Agar medium is melted (15 ml) and cooled to 4
POUR PLATE METHOD
71
are inoculated by touching with a charged loop or by adding the inoculum with pipettes or syringes.
LIQUID CULTURE
