Abstract

Probiotics are living microorganisms if consumed in sufficient quantities can be beneficial for health. One of the potential bacteria as probiotics is Lactobacillus plantarum NHC6 is a lactic acid bacteria isolated from pineapple juice. This study aimed to test the ability of L. plantarum NHC6 as a probiotic in pineapple juice. Probiotics were stored until four weeks under 4°C and 10°C which weekly is monitored data on the amount of microbes, pH, percentage of lactic acid, and total dissolved solids in fermented pineapple juice. The result shows, the shelf time for pineapple juice under 4°C has a lower microbial reduction time rather than the juice storage under 10°C. Probiotics shelf time predicted for 4°C storage was 28.32 weeks and for 10°C storage was 8.67 weeks after production. The changes in physical properties (pH, percentage of lactic acid, and total soluble solids) in 10°C storage is much faster than that off in 4°C, this happens because there is still metabolic activity by bacteria at that temperature.

Abstract

Probiotics are widely used in fish diets to improve health and growth, but a detailed analysis of their impact on fish growth performance has been lacking. This study conducted a meta-analysis of 86 relevant articles out of 627 identified, focusing on specific growth rate (SGR) and feed conversion ratio (FCR). The study examined the effects of different variables, including the number of probiotic strains used, the type of water (freshwater, saltwater, or brackish), and the concentration of probiotics. The results indicated that probiotics had a significant positive effect on both SGR and FCR in fish. There was no notable difference in growth performance between diets with single strains versus multiple strains of probiotics. However, freshwater fish showed a better response to probiotics compared to saltwater and brackish water fish. The analysis found that the minimum effective concentration of probiotics for improving SGR was 7 log CFU/g, while 8 log CFU/g was needed to enhance FCR. Overall, this meta-analysis offers valuable insights into optimizing the use of probiotics in aquaculture, demonstrating that specific factors such as water type and probiotic concentration play critical roles in achieving the best growth performance in fish.
