Module 3 Flashcards
Bifidobacterium classifciation
Actinobacteria –> Actinobacteria –> Actinobacteridae –> Bifidobacteriales
Hight chromosomal G+C content
Bifidobacterium and Propionibacterium
Y morphology
Bifidobacterium
Human milk Isolate
Bifidobacterium
Bifidobacterium Simple Sugars
Fructose-6-P-PK pathway (F6PK)
Bifiodobacterium not LAB because
Lactic acid not end main product
F6PK
F6P –> Erythrose 4P + Acetyl-P (Joins other 2)
Bifid Shunt
1 mole glucose –> 2.5 mol ATP + 1.5 mole acetate + 1 mole lactate
Non-digestible Oligosaccharides (NDOs)
Obtained from complex carbs or enzymatically produced from disaccharides
NDOs
Group of glycans that include various prebiotics and increase Bifidobacterium numbers (selective probiotic effect)
NDO Types
FOS + Galacto (GOS)
Human milk oligosaccharides (HMOs)
B. bifidum and B. longum subsp. infantis
Bifidobacterium can
Hydrolyze complex sugars like HMO to glucose –> glycolytic pathway
Propionibacterium Classification
Actinobacterium –> Propionbacteriales –> Propionibacteriaceae
Anaerobic and aerotolerant
Propionibacterium
