What is Gram Staining of Lactobacilli in Milk about?

1. The student conducted an experiment to identify the bacterial species in "Lactel" milk using the Gram staining technique. 2. The results showed that most bacteria were Gram-positive and stained purple as expected for lactococci, but some Gram-negative bacteria were also present that stained pink. 3. The hypothesis that all bacteria would be Gram-positive was partially correct, as unexpected Gram-negative bacteria were identified, likely due to contamination during sample preparation.
