Continuous Fermentation by Lactobacillus bulgaricus T15 Cells Immobilized in Cross-Linked F127 Hydrogels to Produce ᴅ-Lactic Acid

Kinetic study of continuous whey permeate fermentation by immobilized Lactobacillus helveticus for lactic acid production

A pH-controlled continuous lactic acid fermentation of whey permeate supplemented with yeast extract was carried out with Lactobacillus helveticus entrapped in K-carrageenan-locust bean gum gel beads at various dilution rates and pH set points. A kinetic study of the immobilized cell continuous fermentation in a 1-I stirred-tank reactor containing 33% (v/v) gel beads was carried out with an ori...

Optimization of Cultural Conditions for Lactic Acid Production by Lactobacillus Bulgaricus Attc 11842 Grown on Whey

The effects on the lactic acid (LA) production by thermophile Lactobacillus bulgaricus ATTC 11842 on whey as a basal medium of seven factors namely, temperature °C, pH, Lactose g/l, Yeast extract g/l, corn steep liquor (CSL) g/l, K2HPO4 g/l, and salts g/l (MnSO4, MgSO4 and FeSO4) were investigated, through the statistical analysis of the results by Plackett and Burmann experimental design. pH w...

Effects of Two Probiotics, Lactobacillus Plantarum and Lactobacillus Bulgaricus on Growth Performance and Intestinal Lactic Acid Bacteria of Cyprinus Carpio

Background: The application of probiotics to aquaculture is rather new. Probiotics affect the intestinal microbial flora of fish and subsequently modulate its immune response and growth performance. OBJECTIVES: This study was conducted to evaluate the effect of food supplementation with L.plantarum and L.bulgaricus on growth performance and gut microbiota of Cyprinus carpio. METHODS: For this p...

Mechanically Tough Pluronic F127/Laponite Nanocomposite Hydrogels from Covalently and Physically Cross-Linked Networks

Fermentation of Tomato Juice by Cell Immobilized Lactobacillus acidophilus

INTRODUCTION Probiotics are beneficial microorganisms. When ingested on a regular basis, probiotics can improve overall health, balance the microflora of the intestinal tract, enhance immune system function, and assist in the absorption of vitamins and minerals [1]. The most commonly consumed probiotics are lactic acid bacteria (LAB) including Lactobacillus acidophilus, Lactobacillus plantarum ...
