Summary

Description
English: Photograph of Richard Lenski's long-term evolution experiment with E. coli taken on 25 June 2008. Each flask harbors one of the 12 evolving populations. The photo was taken about 24 h after the cultures were serially transferred, hence they are at stationary phase. The populations grow in DM25 medium, which contains a relatively low glucose concentration so that the culture is not very turbid. However, one population, designated Ara-3, evolved to use the citrate that is also present in the medium. It has a much greater density of cells than the others, and it is therefore much more turbid, owing to the high concentration of citrate in the medium supporting greater cell growth.
Русский: Колбы с 12 популяциями E. coli, участвующими в долговременном эколюционном эксперименте Ричарда Ленски, 25 июня 2008. Культуры перенесены в свежую питательную среду 24 часа назад и уже находятся в стационарной фазе (т.е. глюкоза уже кончилась, деление клеток прекратилось). Популяция взращиваются в питательной среде DM25, которая содержит относительно небольшое количество глюкозы, так что плотность культур не очень велика. Однако одна из популяций, обозначенная как Ara-3, приноровилась питаться цитратом, который тоже входит в состав питательной среды. Это позволило ей достигнуть большей плотности (жидкость в колбе А-3 заметно более мутная, чем в других колбах).
