Translation guide
The community of microorganisms in a particular environment. In Japanese, this is typically expressed with technical terms like 微生物叢 or マイクロバイオータ, but in everyday contexts, phrases like 腸内細菌 (gut bacteria) or 常在菌 (resident bacteria) are more common.
Referring to the collective microorganisms in a specific environment, especially in scientific or medical contexts.
The standard technical term for microbiota, literally 'microorganism flora'. Used in academic and medical writing.
腸内微生物叢のバランスが健康に重要です。
The balance of the gut microbiota is important for health.
A direct loanword from English, commonly used in scientific contexts and increasingly in popular science.
マイクロバイオータの研究が進んでいます。
Research on the microbiota is advancing.
Literally 'bacterial flora', often used interchangeably with 微生物叢 when focusing on bacteria. Slightly more specific.
皮膚の細菌叢は個人差が大きい。
The skin microbiota varies greatly between individuals.
Talking about the microorganisms in the digestive system in a less technical, everyday manner.
The most common way to refer to gut microbiota in everyday Japanese. Literally 'intestinal bacteria'.
ヨーグルトで腸内細菌を整えましょう。
Let's improve our gut bacteria with yogurt.
Referring to the microorganisms that normally live on or in the body without causing disease.
Means 'resident bacteria', the normal microbial inhabitants of the body. Common in medical and skincare contexts.
肌の常在菌のバランスが崩れると肌荒れの原因になります。
When the balance of the skin's resident bacteria is disrupted, it can cause skin problems.
A more formal term for 'normal flora' or 'normal microbiota', used in medical contexts.
正常細菌叢は病原菌から体を守ります。
The normal microbiota protects the body from pathogens.
Microorganisms in a specific environment like soil, water, or built spaces.
Used for microbiota of environmental samples. Technical term.
土壌の環境微生物叢を分析しました。
We analyzed the soil microbiota.
Specifically soil microbiota. Common in agricultural and ecological studies.
土壌微生物叢の多様性が作物の生育に影響します。
The diversity of the soil microbiota affects crop growth.
Both are used in scientific contexts. 微生物叢 is the native Japanese term and may be preferred in formal writing, while マイクロバイオータ is a direct loanword and common in international publications. In everyday health contexts, 腸内細菌 or 腸内フローラ are more natural.
In casual conversation, using 微生物叢 or マイクロバイオータ may sound overly technical. Instead, use 腸内細菌 for gut health or 常在菌 for skin bacteria. If you must use the scientific term, provide context.
A common term in health media, from 'intestinal flora'. Slightly more technical than 腸内細菌 but widely understood.
腸内フローラを改善する食品が人気です。
Foods that improve gut flora are popular.
