Key Difference – LactobacillusvsBifidobacterium

在现代微生物学的背景下，目前正在研究与人体共生相关的不同细菌物种，以识别不同的受益因素。这些细菌物种为宿主提供了不同的好处，其中包括宿主生长和发育的上调。LactobacillusandBifidobacteriumare such two bacterial species that are recognized asprobiotics。益生菌是肠道中存在的受益细菌microbiotathat provides different benefits to the host.Lactobacillus是一个兼性厌氧bacterial species whileBifidobacterium是一种厌氧细菌的强制性。This is the关键区别betweenLactobacillusandBifidobacterium.

什么是Lactobacillus？

Lactobacillusbelongs to the group ofgram-positive bacteria是兼性厌氧生物。考虑其他功能Lactobacillus，，，，they are rod-shaped microaerophilic bacteria. They do not form any spores during reproduction. This species of bacteria is considered as the major species that belongs to the group lactic acid bacteria. In the context of human gut microbiota,Lactobacillus是一个bundantly present. Not only in the human gut, butLactobacillus还居住在生殖系统和尿液系统等的地方，在女性的背景下but Lactobacillus is alsopresent as a major microbial component in the vagina.

These bacteria have the ability to form biofilms in the gut and vagina and thereby prevail during harmful environmental condition.Lactobacilluspresent in the human body exists as mutualistic organisms that protect the body from differentpathogenicintrusions. The human body provides ample of nutrients for the growth and development of the bacterial species and to reproduce successfully within the body. In the context of dairy products,Lactobacillus被认为是益生菌。这些益生菌会提升人类健康，并参与腹泻和不同阴道感染的治疗。Lactobacillus也可以用作皮肤感染的治疗策略eczema。

在Lactobacillus代谢，大多数参与同型代谢的物种以及少数物种涉及异源代谢。同型描述仅糖的产生，而异性含量是指生产乳酸oralcoholsfrom sugars.

什么是Bifidobacterium？

Bifidobacterium是一个non-motile, gram-positive, rod-shaped (branched)obligate anaerobic主要存在于intestines动物和人类。这些细菌被认为是栖息在哺乳动物结肠的主要生物。如同Lactobacillus，，，，Bifidobacterium也用作益生菌。在fermentation碳水化合物，Bifidobacteriumutilizes the fructose-6-phosphate phosphoketolase pathway. These bacteria that present in the human gut involves in asymbioticrelationship with the host and provides beneficiary factors such as good digestion, production of lactic acid and acetic acid and promotes immunity through boosting up the immune system. It was revealed thatBifidobacteriumhas the ability to compete with other gut microorganisms actively and occupy a larger fraction of the gut microbiota.

Key Difference Between Lactobacillus and Bifidobacterium

Figure 02: Bifidobacterium

出来Bifidobacteriumgroup,Bifidobacterium长子是最常见的物种类型。它有一个genome圆形的圆形长度为2,260,000 bp（碱基对）和GC（Guanineand胞嘧啶）60％。该物种目前正在彻底研究中，以识别益生菌品质。Bifidobacterium具有由磷酸酶途径驱动的己糖代谢的独特途径。这种独特的途径被称为双分流。在此途径中，细菌利用酶-6-磷酸磷酸磷酸酶。这也被用作诊断工具，因为在其他革兰氏阳性细菌中找不到这种现象。

What are the Similarities BetweenLactobacillusandBifidobacterium？

乳杆菌和双歧杆菌均革兰氏阳性。
乳杆菌和双歧杆菌都产生乳酸。
乳酸杆菌和双歧杆菌均易受抗生素的影响。
乳杆菌和双歧杆菌都有一个共同的栖息地，这是动物和人类的肠道。
乳杆菌和双歧杆菌都被用作益生菌。

有什么区别LactobacillusandBifidobacterium？

Lactobacillus vs Bifidobacterium
Lactobacillus属于将糖转化为乳酸的疗法厌氧的革兰氏阳性细菌。	Bifidobacterium是一种非运动，革兰氏阳性的，杆状（分支）的厌氧菌细菌，主要存在于动物和人类的肠道中。
Habitat
Milk and dairy products, animal and human intestines, fermented foods are the habitats ofLactobacillus。	人类和动物胃肠道（肠道）是Bifidobacterium。
细胞形态
Lactobacilluscan be cocci or rods.	Bifidobacteriumis present as branched rods or club-shaped.
Major Metabolites
乳酸是主要代谢物Lactobacillus。	乳酸和乙酸是主要代谢物Bifidobacterium。
Oxygen Sensitivity
乳杆菌是一种兼性厌食症（即使在氧气存在的情况下，也具有生活的能力）。	Bifidobacterium是一种强制性的厌食症（不能在氧气存在下生活）。

概括 -LactobacillusvsBifidobacterium

Lactobacillus属于将糖转化为乳酸的疗法厌氧的革兰氏阳性细菌。这种细菌被认为是属于乳酸菌种类的主要物种。Lactobacilluspresent in the human body exists as mutualistic organisms that protect the body from different pathogenic intrusions. Most of the species involve in homofermentative metabolism, and a minority of species involve in heterofermentative metabolisms. These probiotics uplift human health and involve during the treatment of diarrhoea and different vaginal infections.Bifidobacterium是一种非运动，革兰氏阳性的，杆状（分支）的厌氧菌细菌，主要存在于动物和人类的肠道中。Bifidobacterium具有积极与其他肠道微生物竞争的能力，并占据了更大的肠道微生物群。
