The genus Mentha (mint) belongs to the Lamiaceae family, which
includes 25 to 30 species. The species of this genus have been known for their medicinal and aromatherapeutic properties since ancient times and possess a significant economical and commercial reputation. Several
species of Mentha are widely used in culinary and traditional medicines in many parts of the world. Essential oils from Mentha
species have been commonly used as flavoring substance in beverages,
providing a “fresh-like” aroma and taste. Chemical analyses of Mentha species have yielded a number of important phytocompounds belonging to different classes, such as organic acids, flavonoids, sterols, alkaloids, lignans, hydrocarbons, fatty acids, tocopherols, proteins, free sugars, etc. Moreover, the main compounds in mints are essential oils, phenolics, and flavonoids. This review reports the available information on the present status (literature up to early 2020) of the Mentha species and summarizes the chemical constituents, traditional and culinary uses, cultivation, and biological properties. In addition, comprehensive analysis of the antibacterial studies conducted on Mentha species is represented. In effect, Mentha species have been presented here as a viable alternative source of many biological and chemically active compounds which are already known to be of great economic, pharmaceutical, and nutritional importance.

The active bacterial rhizobiomes and root exudate profiles of phytometers of six plant species growing in central European temperate grassland communities were investigated in three regions located up to 700 km apart, across diverse edaphic conditions and along a strong land use gradient. The recruitment process from bulk soil communities was identified as the major direct driver of the composition of active rhizosphere bacterial communities. Unexpectedly, the effect of soil properties, particularly soil texture, water content, and soil type, strongly dominated over plant properties and the composition of polar root exudates of the primary metabolism. While plant species-specific selection of bacteria was minor, the RNA-based composition of active rhizosphere bacteria substantially differed between rhizosphere and bulk soil. Although other variables could additionally be responsible for the consistent enrichment of particular bacteria in the rhizosphere, distinct bacterial OTUs were linked to the presence of specific polar root exudates independent of individual plant species. Our study also identified numerous previously unknown taxa that are correlated with rhizosphere dynamics and hence represent suitable targets for future manipulations of the plant rhizobiome.
