''ビフィズス菌''属のメンバーは酸素<sub>2</sub>に敏感であるため、一般的にプロバイオティクスの活性は嫌気性の生息環境に限定される。最近の研究では、いくつかの''ビフィドバクテリウム''株が様々なタイプの[[wikt:oxic|oxic]]増殖を示すことが報告されている。低濃度のO<sub>2</sub>やCO<sub>2</sub>は、これらの''ビフィズス菌''株の増殖に刺激的な効果をもたらす。異なるO<sub>2</sub>濃度下での増殖プロファイルに基づき、''Bifidobacterium''種は4つのクラスに分類された： O<sub>2</sub>-過敏性、O<sub>2</sub>-感受性、O<sub>2</sub>-耐性、そして[[microaerophilic/ja|微好気性]]である。好気性増殖阻害の主な要因は、増殖培地中の[[hydrogen peroxide/ja|過酸化水素]]（H<sub>2</sub>O<sub>2</sub>）の生成であると提唱されている。O<sub>2</sub>感受性の''Bifidobacterium bifidum''を精製し、H<sub>2</sub>O<sub>2</sub>を形成する[[NADH/ja|NADH]][[oxidase/ja|オキシダーゼ]]が発見された。''b''型[[dihydroorotate dehydrogenase/ja|ジヒドロオロテートデヒドロゲナーゼ]]と同定した。この酵素は、高好気性環境におけるH<sub>2</sub>O<sub>2</sub>産生に関与している可能性が示唆された。

==Clinical uses==
[[ulcerative colitis/ja|潰瘍性大腸炎]]の従来の治療にプロバイオティクスとして''ビフィズス菌''を加えることは、寛解率の改善と寛解維持の改善に関連することが示されている。いくつかの''ビフィズス菌''株は重要なプロバイオティクスと考えられており、食品産業で使用されている。ビフィズス菌の異なる種および/または菌株は、腸内微生物の[[homeostasis/ja|恒常性]]の調節、腸粘膜に定着および/または感染する病原体および有害細菌の抑制、局所的および全身的な免疫応答の調節、微生物叢内の発癌性酵素活性の抑制、ビタミンの産生、多くの食事性化合物の生物活性分子への変換など、様々な有益な健康効果を発揮する可能性がある。ビフィズス菌は腸粘膜バリアを改善し、腸内の[[lipopolysaccharide/ja|リポ多糖]]レベルを低下させる。
Adding ''Bifidobacterium'' as a probiotic to conventional treatment of [[ulcerative colitis]] has been shown to be associated with improved rates of remission and improved maintenance of remission. Some ''Bifidobacterium'' strains are considered as important probiotics and used in the food industry. Different species and/or strains of bifidobacteria may exert a range of beneficial health effects, including the regulation of intestinal microbial [[homeostasis]], the inhibition of pathogens and harmful bacteria that colonize and/or infect the gut mucosa, the modulation of local and systemic immune responses, the repression of procarcinogenic enzymatic activities within the microbiota, the production of vitamins, and the bioconversion of a number of dietary compounds into bioactive molecules. Bifidobacteria improve the gut mucosal barrier and lower levels of [[lipopolysaccharide]] in the intestine.

母乳には高濃度の乳糖と低量のリン酸塩（[[pH buffer/ja|pH緩衝剤]]）が含まれている。そのため、母乳が乳児の消化管内で乳酸菌（ビフィズス菌を含む）によって発酵されると、pHが低下してグラム陰性菌が増殖しにくくなる可能性がある。
Mother's milk contains high concentrations of lactose and lower quantities of phosphate ([[pH buffer]]). Therefore, when mother's milk is fermented by lactic acid bacteria (including bifidobacteria) in the infant's gastrointestinal tract, the pH may be reduced, making it more difficult for Gram-negative bacteria to grow.

== ビフィズス菌と乳児の腸内環境{{Anchor|Bifidobacteria and the infant gut}} ==
== Bifidobacteria and the infant gut ==
ヒトの乳児の腸は、出生までは比較的無菌状態で、周囲の環境や母親から細菌を取り込む。乳児の腸を構成する[[microbiota/ja|マイクロバイオータ]]は成人の腸とは異なる。乳児がマイクロバイオームの成人期に達するのは3歳頃で、マイクロバイオームの多様性が高まり、安定し、固形食に切り替わる時期である。母乳で育てられた乳児は、主に粉ミルクで育てられた乳児に比べ、''ビフィズス菌''に早くからコロニー形成される。ビフィドバクテリウム''は乳児の腸内マイクロバイオームで最も一般的な細菌である。乳幼児では[[genotype/ja|遺伝子型]]の経時的変動が大きく、成人の''ビフィドバクテリウム''に比べて安定性に欠ける。3歳未満の乳幼児はマイクロバイオーム細菌の多様性は低いが、成人と比較すると個体間の多様性は高い。 乳児の腸内細菌叢の''ビフィズス菌''の減少と多様性の増加は、母乳摂取量の減少と固形食摂取量の増加に伴って起こる。哺乳類の母乳にはすべて[[oligosaccharide/ja|オリゴ糖]]が含まれており、自然淘汰が見られる。ヒトの母乳のオリゴ糖は酵素で消化されず、消化管を通過した後、大腸で微生物叢によって分解される。ビフィズス菌''種のゲノム''[[Bifidobacterium longum/ja|B. longum]]''、B. bifidum、[[Bifidobacterium breve/ja|B. breve]]には、ヒトの母乳オリゴ糖の一部を加水分解できる遺伝子が含まれており、母乳栄養の乳児に多く見られる。ヒトによって産生された[[Glycan/ja|糖鎖]]は、''ビフィズス菌''の餌とエネルギーに変換される。
The human infant gut is relatively sterile up until birth, where it takes up bacteria from its surrounding environment and its mother. The [[microbiota]] that makes up the infant gut differs from the adult gut. An infant reaches the adult stage of their microbiome at around three years of age, when their microbiome diversity increases, stabilizes, and the infant switches over to solid foods. Breast-fed infants are colonized earlier by ''Bifidobacterium'' when compared to babies that are primarily formula-fed. ''Bifidobacterium'' is the most common bacteria in the infant gut microbiome. There is more variability in [[genotype]]s over time in infants, making them less stable compared to the adult ''Bifidobacterium''. Infants and children under three years old show low diversity in microbiome bacteria, but more diversity between individuals when compared to adults.  Reduction of ''Bifidobacterium'' and increase in diversity of the infant gut microbiome occurs with less breast-milk intake and increase of solid food intake. Mammalian milk all contain [[oligosaccharide]]s showing natural selection. Human milk oligosaccharides are not digested by enzymes and remain whole through the digestive tract before being broken down in the colon by microbiota. ''Bifidobacterium'' species genomes of ''[[Bifidobacterium longum|B. longum]], B. bifidum, [[Bifidobacterium breve|B. breve]]'' contain genes that can hydrolyze some of the human milk oligosaccharides and these are found in higher numbers in infants that are breast-fed. [[Glycan]]s that are produced by the humans are converted into food and energy for the ''B. bifidum.'' showing an example of [[coevolution]].
