Bifidobacteria – Bifidobacterium species

blaehungen-800x675Bifidobacteria fight harmful bacteria and pathogens in the entire digestive system of humans and vagina of women. Due to their anaerobic (energy production without oxygen) metabolism, bifidobacteria are able to gain acceptance in the colon, whereas lactobacilli mainly dominate the small intestine. The intestinal bifidobacteria feed on fibres or undigested carbohydrates. With appropriate nutrition, they settle permanently in the intestine. In adults, about 25% of intestinal bacteria are bifidobacteria, and in babies up to 95% of intestinal bacteria are bifidobacteria.

Naturally, bifidobacteria occur in mother’s milk (from healthy mothers). If breastfeeding is not breastfed, the mother is not healthy or antibiotics have been/are administered, probiotics should be considered.

Bifidobacteria survive the stomach passage, among other things a condition for the fact that Bifidos may be counted among the probiotics.

Bifidobacteria stimulate the production of antibodies and somehow – don’t ask me how – can stimulate the growth of certain immune cells. Perhaps because they are seen as intruders, but in the end they do not claim the immune system?

Bifidos produce Vitamins. of the B-complex That sounds good, doesn’t it? Unfortunately Bifidos are found in the colon, but vitamins are absorbed mainly in the small intestine. At least some old-school doctors argue against the now universally accepted importance of intestinal flora for our health.
Bifidobacteria acidify the large intestine by fermenting glucose to lactic acid. Acid production is not as strong as in the case of lactobacilli and takes place completely under exclusion of oxygen.

Bifidobacteria excrete Bifidin. It is a poison used to fight pathogenic intestinal bacteria (e. g. rotting bacteria such as clostridia, salmonella, listeria or the harmful E. -Coli strains). However, the low PH value in its environment is sufficient to prevent the bacteria mentioned above from proliferating and spreading.

Bifidobacteria also have an effect in the human vagina, lowering the pH-value and keeping the women away with bifidin harmful germ and vaginal fungi.

In Studies, a tendency has been shown that bifidobacteria reduce flatulence and (particularly B. infantis) normalize stool consistency, both in the stools and in the stools.

Bifidobacteria also feed glucose. But if we want to feed the bifidobacteria in our large intestine, then we need indigestible dietary fibres, which are not absorbed in the small intestine. They are therefore specialized in the metabolism of oligosaccharides and polysaccharides.

Bifidobacterium fermentation

Bifidobacteria degrade sugar as a special form of heterofermentative lactic acid fermentation (bifidobacterium fermentation) via a complicated energy metabolism pathway. The sugars are broken down to acetic acid and lactic acid. Bifidobacterium fermentation produces 25% more energy / ATP than the general heterofermentative lactic acid fermentation of e. g. lactobacilli. A representative of the genus Lactobacillus develops more acidity during lactic acid fermentation than the bifidobacteria.

Bifidobacterium sp.

  • Normal value in the large intestine: 106-1011 (These are very many. It underlines how important they are for our healthy intestinal flora.)
  • Oxygen consumption: optional anaerobic
  • In Latin, bifidus means approximately, split or forked.
  • rod bacteria
  • often club-shaped (“coryneform”).
  • gram positive
  • Supporting the defence against pathogens
  • Metabolism of oligosaccharides and polysaccharides
  • motionless
  • nonporous
  • form smooth microcolonies without filaments on agargel culture media.
  • have a similarity to corynebacteria
  • non pathogenic = harmless to humans
  • Bifidobacteria do not possess aldolase (Fructose-1,6-bisphosphate aldolase is the enzyme for splitting fructose-1,6-bisphosphate into dihydroxyacetone phosphate (DHAP) and glycerinaldehyde-3-phosphate (GAP)) and are therefore dependent on their special form of fermentation for energy production:

Bifidobacterium adolescentis

  • Adolescens (lat.) = adolescent
  • Especially in the large intestine of adolescents = babies – children
  • Bifidobacterium adolescentis belongs to the healthy human and animal intestinal flora. The first contact with adolescentis in the intestine occurs immediately after birth. The population is decimated in later adulthood by factors such as diet, stress and antibiotics. Bifidobacterium adolescentis was first isolated by Tissier in 1899 in the faeces of breastfed newborns. Tissier was the first researcher to initiate the therapeutic use of bifidobacteria for the treatment of infant diarrhoea with high oral doses of bifidobacteria. Since then, their presence in the intestine has been linked to a healthy intestinal flora.

Bifidobacterium animalis

Probiotic preparations with Bifidobacterium animalis

  • OMNi-BiOTiC 6

Bifidobacterium animalis subsp. lactis

  • Compared to other bifidobacteria, it has a particularly high resistance to gastric acid and bile salts, making it particularly suitable as a probiotic.
  • High adherence to the intestinal mucosa
  • Activia has had the name Bifidus regularis protected for a strain of Bifidobacterium animalis.

Bifidobacterium bifidum

  • Very important bifidobacterium in human colon
  • especially for children/babies
  • Acidifies the colon
  • thus inhibits the growth of harmful bacteria
  • Important for the immune system
  • Stimulates the activity of macrophages (B-lymphocytes and phagocytes/eating cells)
  • Promotes the functions of the digestive system
  • Productions of B-vitamins
  • Adheres very well to the intestinal wall
  • Very resistant to gastric acid and bile fluid
  • is important for the immune system.

Bifidobacterium breve

  • One of the strongest representatives of bifidobacteria
  • survives bile salts and stomach acid
  • Breve = short
  • Bifidobacterium breve communicates with the immune system
  • Thereby regulation of inflammatory reactions.
  • Theory: Seems to influence the production of hormones.
  • Also available in the vagina.
  • Inhibits fewer pathogenic bacteria than B. bifidum. E. g. Escherichia coli and Enterococcus
  • Here’s how you feed these bifidos: Substrate

Bifidobacterium bulgaricus

There’s no such thing. You probably mean Lactobacillus Bulgaricus

Bifidobacterium infantis

  • Especially likes to thrive in the large intestines of babies. Replaced by B. bifidum after feeding and especially after weaning. The word infantile should be familiar to everyone: immature, childish.
  • Also involved in digestion
  • Producer of B-complex vitamins:
    • Folic acid,
    • Thiamine (vitamin B1),
    • Pyridoxine (vitamin B6),
    • Biotin (vitamin B7)
    • Niacin

Bifidobacterium longum

  • Bifidobacterium longum is the strain of human bifidobacteria, the beneficial effects of which have been best researched.
  • Contained in some yoghurt varieties.
  • More than 40 scientific journal articles have highlighted the fact that it improves the intestinal environment and helps to maintain a healthy immune system, combat infections and that it also promotes bone strength by improving calcium uptake due to the acidity of the intestinal environment.
  • Has the ability to increase the production of immunoglobulin A (IgA). Immunoglobulin A can repel toxic antigens from food and thus protect the intestinal mucosa.
  • Prevents diarrhoea caused by antibiotics.
    Inhibits harmful germs such as…

    • candida
    • enterococcus
    • Escheria Coli
    • staphylococcus aureus
    • streptococcus bacteria
  • Ability to assist in the digestion of lactose.
  • Facilitates the formation of biotin in the digestive tract.
  • Scientific work has also revealed:
    • The number of bifidobacteria in the colon flora decreases with age. Scientific studies have shown that B. longum can improve the intestinal flora of the colon of elderly people. B. longum improves the intestinal environment and over a longer period of time the resistance to infections.
    • The ingestion leads to a significant increase of the relative bifidobacteria in the entire intestinal flora. This naturally also results in the reduction of putrefactive bacteria and products such as ammonia.
    • In order to reduce the risk of intestinal infections, B. longum can stimulate colonization of the intestine with bifidobacteria in low weight premature babies.
      In case of constipation, it regulates intestinal passage because it lowers the ammonia content, decreases the activity of some enzymes in the stool and increases the bowel frequency.
    • longum inhibits the development of cancer.
  • Here’s how you feed these bifidos: Substrate

By lowering the pH-value by the acids excreted by B. longum, the calcium uptake increases, which in turn could be beneficial for bone growth or bone strength.
