New Delhi: Six Petri dishes in Google colours form the interactive Google doodle on Julius Richard Petri's 161st birth anniversary that falls on Friday, May 31, 2013.
The shallow cylindrical laboratory glassware was invented by Julius Richard Petri in 1877 while assisting the pioneering bacteriologist Robert Koch.
Petri dishes are used by microbiologists for growing cell cultures. Nowadays single-use disposable Petri dishes are preferred over glass. Petri dishes are also known as Petri plate or cell culture dish.
German bacteriologist Julius Richard Petri was born on May 31, 1853 in Barmen and died aged 69 on December 20, 1921 in Zeitz.
The Julius Richard Petri Google doodle recreates the microbe culture process and the resultant microbial growth spells out the Google letters.
