“…In our study, EPS production was also influenced by fermentation temperature and time, initial pH and medium. Imran Relative capacity(%/mg) EPS production Relative Capacity production of Lactobacillus plantarum reached a maximum in stationary phase of growth (32 h), and then decreased in declining phase [31], which was consistent with our results. This decrease in EPS production after prolonged culture was reported earlier [32].…”

The correlation between exopolysaccharide production of Lactobacillus kimchi SR8 under different culture conditions and the DPPH radical scavenging activity of exopolysaccharide was studied. Lactobacillus kimchi SR8 produced 228.24 ± 2.23 mg/L exopolysaccharides with sucrose as the carbon source, Beef Extract-Peptone (2:1) as the nitrogen source and an initial pH of 6.50, whilst the DPPH radical scavenging activity of exopolysaccharides was only 6.85% ± 0.77% at a concentration of 0.20 mg/mL. However, the strain produced 206.79 ± 2.23 mg/L exopolysaccharides with glucose as the carbon source, Peptone-Tryptone (1:1) as the nitrogen source and an initial pH of 7.00, and the DPPH radical scavenging activity of exopolysaccharides increased to 28.34% ± 0.32% at the same concentration. The results showed no correlation between the exopolysaccharide production of lactic acid bacteria and the DPPH radical scavenging activity of exopolysaccharide. Therefore, the antioxidant activity should be taken into consideration when measures are taken to increase exopolysaccharide production if greater antioxidant activity of exopolysaccharides is preferred.

“…Other studies suggest that optimum pH and temperature are 7.0 and 30 0 C, for growth synthesis and EPS by E. cloacae WD7 (Prasertsan et al, 2008) and E. agglomerans WD50 (Prasertsan et al, 2006). According to Imran et al (2016), in neutral pH, EPS production improved both in L. plantarum NTMI05 (0.35 ± 0.03 g/L) and NTMI20 (0.32 ± 0.02 g/L).…”

: Exopolysaccharide (EPS) is a complex mix of macro-molecular electrolyte contained in the outer cells of bacteria excreted as mucus and has a role in soil aggregation. This study aims to obtain bacteria that have a high potential for exopolysaccharide-producing bacteria. A total of 112 isolates of exopolysaccharide-producing bacteria were isolated from rubber soil rhizosphere, secondary forest, and shrubs in PT. Hutan Ketapang Industri is the result of isolation on ATCC no.14 medium. Based on the observations of a morphological colony of these isolates, most of them had similarities of color and shape but only 25 colonies are different isolates were obtained based on colony morphology. However, only 10 isolates formed a thick mucus or slimy when cultured on MacConcey agar. The results show that the obtained three isolates of exopolysaccharide-producing bacteria have a higher value of the dry weight i.e. isolates RB292 (7.53 mg/mL) followed by RB51 (7.55 mg/mL), and RB241 (1.75 mg/mL) with 2% sucrose. Isolates RB51 and RB292 increased significantly soil aggregate stability at 2% dosage of organic matter with soil aggregate stability index from 30.61% to 47.87% and 45.79%. Homology of the isolates with known bacteria i.e. isolate RB51 was 98.86% homolog with Klebsiella sp. LW-13, isolate RB241 was 98.65% homolog with Klebsiella pneumonia strain DSM 30104 and isolate RB292 was 98.83% homolog with Burkholderia anthina strain MYSP113.

“…Ismail and Nampoothiri (2010) found that EPS production by L. plantarum (MTCC 9510) was 210 mg/L when the media was supplemented with 2% sucrose. When supplementing the media with 2% sucrose, Imran et al (2016) obtained 250 mg/L EPS yield from L. plantarum (NTMI05 and NTMI20). Moreover, Sánchez, Martínez, Guillén, Jiménez-Díaz, and Rodríguez (2006) found that carbon source has a marked influence on EPS production from L. pentosus (LPS26) and EPS yield of 560 mg/L was obtained when using 30 g/L glucose.…”

This study aims to evaluate the probiotic properties of Lactobacillus strains producing exopolysaccharides (EPS) isolated from different Malaysian fermented foods. Thirty lactobacilli species were isolated, and six of these (TAP1, PIC7, BU11, BU14, TAP16, and TEMP9) were shown to exhibit probiotic characteristics with the potential to produce EPS. The isolates were evaluated for their tolerance to low pH, bile salts, antimicrobial potential, and cell surface properties. The strains were identified using API50CHL and 16S rRNA gene sequences as Lactobacillus belonged to the species fermentum and plantarum. The Lactobacillus strains exhibited high survivability tolerance to low pH and bile salts (above 90%). All strains exhibited auto-aggregation (33.63-59.63%), co-aggregation (24.37-41.9%), and hydrophobicity (16-65.77%) ability. The strains displayed no transferrable antibiotics and antagonistic activity against pathogenic bacteria. Therefore, it indicates that Lactobacillus strains could act as promising probiotic candidates.
