Microbes of anti-social odor

Human odors depend on many extrinsic (such as food or clothing) and intrinsic factors - localized or systemic. In recent years, microbes responsible for localized malodors - bad breath caused by oral bacteria and axillary odor - have been mapped by using next generation sequencing approaches. However, intestinal microbes responsible for systemic malodor (whole-body and extraoral halitosis), remain to be identified.

 Our preliminary analysis of culture-, PCR- and 16S-RNA-based data donated by MEBO and PATM community members show that there are no easy answers.

Chemicals in food affecting body odor

Volatile compounds (complex organic and simple like hydrogen sulfide and ammonia), together with sugars and acids, are the main chemicals determining the characteristic aroma of food, as well as odors related to human body.

The bad smells are generally the result of a combination of odorous sulfur compounds and ammonia.

Volatile sulfur compounds are produced through bacterial metabolism of sulfur amino acids such as cysteine and methionine. High sulfur content in food is another source.

Choline  - a quaternary saturated amine  - can lead to increases in the amount of trimethylamine responsible for sweet and sickly, fish-like smell.

How to estimate the amount of choline, sulfur and sulfur-containing aminoacids in your food?
You can do it easily with Aurametrix.
