A sugar-rich apple pulp waste generated from fruit processing for juice production was used as the sole carbon source cultivation of Alteromonas macleodii Mo169, a marine bacterium known its EPS-secreting ability. The strain efficiently utilized glucose and fructose present in waste, reaching biomass EPS 9.20 ± 0.61 3.51 0.08 g L−1, respectively, 24-hour bioreactor cultivation. Two high molecular weight (Mw) fractions (1.7 0.0 0.74 MDa) were detected sample recovered cell-free supernatant by dialysis. compositional analysis revealed presence (31.1 0.2 mol%), arabinose (23.9 0.1 mannose (17.3 glucosamine (10.3 0.5 galactose (8.7 mol%) galacturonic acid well content sulphate (6.0 wt%). Given Mw polysaccharide probably pectin, fraction sugar monomers might be attributed to that polymer, which together with A. Mo169 EPS.

Exopolysaccharides (EPSs) are large-molecular-weight, complex carbohydrate molecules and extracellularly secreted bio-polymers released by many microorganisms, including lactic acid bacteria (LAB). LAB well known for their ability to produce a wide range of EPSs, which has received major attention. LAB-EPSs have the potential improve health, applications in food pharmaceutical industries. Several methods been developed optimized recent years producing, extracting, purifying, characterizing LAB-produced EPSs. The simplest method evaluating production EPSs is observe morphological features, such as ropy mucoid appearances colonies. Ethanol precipitation widely used extract from cell-free supernatant generally purified using dialysis. most commonly quantify content phenol-sulfuric acid. structural characteristics identified via Fourier transform infrared, nuclear magnetic resonance, X-ray diffraction spectroscopy. molecular weight composition monosaccharides determined through size-exclusion chromatography, thin-layer gas high-performance liquid chromatography. surface morphology observed scanning electron microscopy atomic force microscopy, whereas thermal thermogravimetry analysis, derivative thermogravimetry, differential calorimetry. In present review, we discuss different existing detailed study provide comprehensive guide on LAB-EPS preparation, critically methods, addressing knowledge gaps key challenges, offering solutions enhance reproducibility, scalability, support both research industrial applications.

Abstract Halomonas sp. DT-Z4, a moderately halophilic strain isolated from saline and alkali soil in Qinghai Province, was used to characterize the structure function of novel extracellular polysaccharide (EPS-Z4). By optimizing fermentation conditions (carbon source: sucrose 9% w/v; Nitrogen peptone 12 g/L; pH 9.0; 25°C), EPS production reached 3.09 g/L, indicating its adaptability extreme salinity environment. Structural characterization showed that EPS-Z4 is fructose-dominated heteropolysaccharide (97.6%) with small amounts glucose (1.4%), glucuronic acid (0.5%) amino sugar (0.1%). Fourier transform infrared spectroscopy (FTIR) thermogravimetric analysis (TGA) were confirm α-(1→6) linkage high thermal stability (Td = 275.9°C). Scanning electron microscopy (SEM) it had dense lamellar network morphology zeta potential -21.4 mV, moderate colloidal stability. Functional excellent water solubility (WSI 85.79%) oil retention (OHC 321%), which better than most traditional microbial polysaccharides. could be as stabilizer for high-temperature food processing biological agent saline-alkali remediation.
