methyl red test for lactobacillus spp. is positive,because it produce lactic acid after incubation . you’re wrong. please crt it.
Hi, Thank you for your comment. Since Lactobacillus genus have many species, some of them are MR +ve. But most the Lactobacillus are MR -ve which I found in some papers. I changed it to mostly MR -ve, some +ve.
Here are the links the research article:

https://www.sciencedirect.com/science/article/pii/S1687157X18300234 (this paper say MR/VP -ve)
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9144466/ (this paper say both MR +ve and MR -ve)
