Influence of different carbon sources on exopolysaccharide production by Lactobacillus delbrueckii subsp. bulgaricus (B3, G12) and Streptococcus thermophilus (W22)

Abstract: Exopolysaccharides (EPSs) production was studied by Lactobacillus delbrueckii subsp. bulgaricus (B3, G12) and Streptococcus thermophilus (W22) in the medium containing various carbon sources (glucose, fructose, sucrose or lactose). For all the strains, glucose was the most efficient carbon source and B3, G12 and W22 strains produced 211, 175 and 120 EPS mg/L respectively. Also, the influence of different concentrations of glucose (5,10,15,20,25,30 g/L) on EPS production and growth was studied. The results in… Show more

“…Among the functional attributes, extracellular polysaccharide [exopolysaccharide (EPS)] production by LAB influences the physicochemical behavior of fermented foods and contributes toward “functional” foods by interacting with the immune system of consumers ( Caggianiello et al, 2016 ), guards the bacterial cells against severe stress, and provides adhesion to surfaces and biofilm formation ( Yuksekdag and Aslim, 2008 ).…”

“…The precipitated proteins and bacterial cells were removed after centrifugation (13000 ×g for 10 min at 4 °C). The supernatants containing EPS were mixed with a double volume of ethanol and then stored at 4 °C for 24 h. The precipitated EPS was collected by centrifugation (10000 ×g for 10 min at 4 °C) (repeat two times), and then dissolved in distilled water for further analysis [3,8].…”
