Effect of Aloe vera juice on growth and activities of Lactobacilliin-vitro

Abstract

In present investigation, different concentrations of Aloe vera juice incorporated into the growth media of Lactobacilli were tested to observe the effect on growth and activities of these bacteria. From the results obtained, it was observed that aloe vera juice at a concentration of 5% v/v was effective in promoting the growth of L. acidophilus, L. plantarum and L. casei, as evident from the fall in pH and increased acidity, as well as from the improved generation time. At 15 to 25% concentration, growth was unaffected as compared to the controls; however, concentration higher than 25%v/v discouraged the growth. Overall, it was concluded that Aloe vera juice or gel at a particular concentration could possibly be used in combination with probiotic Lactobacillus strain(s) as a combinational therapy for gastrointestinal disorders and cardiovascular diseases.
