We support Agar’Art

Published on 25 May 2022 We support Agar'Art

INTERSCIENCE is proud to support the 1st French Agar Drawing Contest!
Above all, we want to promote the scientific field, strengthen the links between institutions and give rise to vocations in microbiology. Each year’s theme is related to current events and is chosen to appeal to as many people as possible

Laureates du concours Agar Art chez interscience
Since 2017, this competition created by Sandra Ferrer, a microbiology teacher at the University of Auch, offers high school and university students the opportunity to discover microbiology and good laboratory practices through this competition.

The INTERSCIENCE teams were happy to receive the winners of the Agar’Art competition in the company’s showroom to congratulate them. They were able to manipulate ScanStation; the incubator and real time colony counter, with their Petri dishes.

A very positive experience!

LEGT Sainte Croix - Saint Euverte - ORLEANS
Students: COCHARD Thylane - CZAJKA Jade - SANCHEZ Ornella
Medium: HEKTOEN agar with Proteus mirabilis and Escherichia coli

On the HEKTOEN medium:

Proteus mirabilis is used to draw the planet, tree trunk, branches, flower stems, wings of small butterflies. Biochemical characteristics of the strain: Lactose, sucrose and salicin - (H2S-) hence the blue color.

Escherichia coli is used to draw the flowers of the tree, the branches, the big butterfly, the petals of the flowers. Biochemical characteristics of the strain: Lactose + (H2S-) hence the yellow-orange color.

Green Venice High School - NIORT
Student: RONDARD Norah
Medium: Kligler with Citrobacter freundii, Serratia marcescens, Micrococcus luteus

To make this drawing I used the kligler medium (red at the beginning) because the colors I chose develop only on this medium. I seeded with the help of toothpicks to be more precise in the drawing.
I decided to use as bacteria :

Citrobacter (it produces H2S at 37°C which allows to make black, and acidifies the medium which will become yellow) for the contours of the flower.

The Serratia (it produces a pink pigment at 30°C) by small touches for the interior of the petals.

The Micrococcus (it produces a yellow pigment at 37°C) by small touches on the top of the flower.
To obtain these colors I had to do two incubations. The first one was at 30°C for 24 h to facilitate the development of Serratia and the second one was in anaerobic conditions at 37°C for 24 h so that there is production of H2S by the Citrobacter.
The agar that I made contained a little too much water which created a strong condensation during the incubation.

Lycée la Forbine - MARSEILLE
Student: VALANCONY cory
Medium: Baird parker medium with Staphylococcus aureus.

Black coloration of Staphylococcus colonies by bacterial reduction of tellurite, colors obtained by adding pH indicators (bromothymol blue and cresol red) + base.
