Abstract:
Lactic acid bacteria (LAB) are bacteria that produce lactic acid. LAB in general can live
naturally in vegetables and fruits including banana peels. Banana peel is rich in
carbohydrates so that it can be a substrate for LAB growth. This study aimed to isolate
and characterize LAB from the peel of sweet banana (Musa acuminata). Isolation of
LAB from banana peels was carried out using the spread plate method using Man
Rogosa Sharpe Agar selective medium. All morphological characterization,
physiological and biochemical tests were investigated. The results of the isolation
obtained 5 LAB isolates. Based on the colony morphological test, all isolates were
Gram-positive bacteria. They showed variation based on physiological and biochemical
tests.
