13) . For this am thankful.This is remarkably helpful. Just curious.I am samiksha working as a microbiologist in ferm we are using macconkeys agar for water pathogen testing some times we found some submerged precipitation like something but not grow when subculture, in macconkeys agar plate after 60 to 72 hrs of incubation at 30 to 35 degrees incubation. Natural isolates from soil or water typically produce a small, rough colony. Pseudomonas aeruginosa: Pseudomonas aeruginosa on tryptic soy agar. 18).

Then plates were incubated at 37°C for 24 h. P. aeruginosa colonies were identified by standard bacteriological methods[8,9,10,11,12] and confirmed by 16S rDNA- based PCR assay. MacConkey agar is used for the isolation of gram-negative enteric bacteria and the differentiation of lactose fermenting from lactose non-fermenting gram-negative bacteria. In this way, lactose-fermenting colonies were surrounded by a haze of precipitated bile.

The medium was first developed by Lowburry and is a modification of Tech Agar. Sheep Blood Agar medium. Good evening sir I don’t understand you said macconkey agar inhibits the growth of gram positive bacteria but you are saying that staphylococcus gives a pale pink colour on this culture midumThe selective action of this medium is attributed to crystal violet and bile salts, which are inhibitory to most species of gram-positive bacteria but not all.
MacConkey agar is a selective medium used for the isolation of non-fastidious Gram-negative rods, particularly members of the family Enterobacteriaceaeand the genus Pseudomonas, and the differentiation of lactose fermenting from lactose non-fermenting Gram-negative bacilli. Pseudomonas aeruginosa is a gram-negative, rod-shaped, asporogenous, and monoflagellated bacterium that has an incredible nutritional versatility. It may be that Enterococcus and Staphylococcus ferment lactose, but wouldn’t the crystal violet and bile salts inhibit their growth? Initially couldn’t understand this MacConkey that i encountered in the microbiology lab but now i can understand it’s uses. The parent company Zodiac Brand Space Pvt. Typical colony morphology of our strains of Enterobacteriaceae and Pseudomonas aeruginosa on MacConkey agar is as follows: 1. Registrations open for the biotech industrial training program starting April/May/June/July 2020.

Mac Conkey’s is a selective and differential medium for Gram negative bacteria .
