Other striking examples are the bacteria Escherichia coli evolving the ability to use citric acid as a nutrient in a long-term laboratory experiment, Flavobacterium evolving a novel enzyme that allows these bacteria to grow on the by-products of nylon manufacturing, and the soil bacterium Sphingobium evolving an entirely new metabolic pathway that degrades the synthetic pesticide pentachlorophenol.
Conto sané pinih dangan inggih punika bakteri Escherichia coli sané nglimbakang kawagedan ipun nganggén asam sitrat pinaka nutrisi ring panyeleh laboratorium jangka panjang, Flavobacterium nglimbakang  enzim anyar sané mresidayang ngawé bakteri puniki mentik ring produk sampingan saking makarya nilon, miwah bakteri tanah Sphingobium nglimbakang pamargi metabolisme sané pinih anyar sané nedunang pestisida sintetis pentachlorophenol.
