I cultured Lactococcuc lactis subsp. lactis on M17 Media and obtained 6 x 106, 5 x 106 and 3 x 106 cfu/mL in three replicates. What should be the average value that I should use?
We we usually indicate microbiological counts to one decimal place, in your case it should be 4,7 x 106 cfu/ml. However, most often we use decimal logarithms - in your case 6,67 log cfu/ml.
Dear Monika, Thank you very much for your answer . I really wants to know how should we need to average the value for three replicates.
Hi
The numbers in any starter was numbers approximation, It was effect more condition you can used spectrophotometerter method very best in bacteria count
Simply 4.6 x10E6 CFU/ml. But anyway, bear in mind that you speak of a log scale, meaning the actual differences among these three counts are not so high...
Thank you very much for your valuable answers. I have already submitted the revised manuscript to the editorial office today. It will be published soon and I will upload it as early as possible once it get published.
You can usually take average value of three counts, so it would be 4.7 X106.
