In this study, the plate casting method was successfully used to prepare biocomposite films containing EPS from probiotic Enterococcus faecium MC-5 in combination with PVA and chitosan. The findings demonstrated that EPS was uniformly distributed in the film matrices and significantly improved the physicochemical properties of the resulting composi...

Rhizophora mucronata Leaves Polysaccharide (RMLP) was extracted and purified from the mangrove Rhizo-phora mucronata leaves by anion-exchange and size-exclusion column chromatography. Physicochemical characterization of RMLP was evaluated by spectrtoscopic analysis (FT-IR, 1 H & 13 C NMR) and RP-HPLC. The molecular weight of RMLP was found to be 2....

The Box-Behnken design was applied to determine the optimal parameters of the extraction condition by using the response surface methodology (RSM) from the leaves of Sonneratia caseolaris L. The result indicates the best-optimized conditions used for the extraction of polysaccharides at 84.02 °C temperature, 3.12 h time, and 27.31 mL/g for the wate...

The selenium nanoparticles (SeNPs) linked with exopolysaccharide (EPS) of E. faecium MC-5 were successfully produced. UV–Vis spectra, DLS, zeta potential, SEM, TEM, FT-IR, thermogravimetric analysis-DSC, and X-ray diffraction measurements were used to characterize the SeNPs in terms of formation, size, stability, and functional group attachment, mo...

E. faecium MC-5 was isolated and characterized from the gut content of C. carpio and supplemented with a pellet diet at the ratio of 1.0 × 10⁶, 1.0 × 10⁹, and 1.0 × 10¹² cfu g–1. Then it was fed to Cirrhinus mrigala for 42 days and the growth performances were evaluated. The growth performance of experimental groups was significantly (P < 0.05) inc...

The goal of this study was to determine the unique characteristics of Enterococcus faecium MC-5, a probiotic bacteria isolated from the intestine of a fish, Cyprinus carpio specularis, collected from Dal Lake in Srinagar, Kashmir, India. For this, the important valuable probiotic attributes, some functional properties, and safety assessments were a...

Avicennia marina mangrove leaves polysaccharide (AMLP) was used for the synthesis of polysaccharide-based selenium (AMLP-SeNPs) and silver nanoparticles (AMLP-AgNPs). The synthesized nanoparticles were further characterized by UV-Vis, DLS, FT-IR, X-ray diffraction, and HR-TEM analysis. A 60-day (8 weeks) feeding trial experiment was conducted to in...

In the present study, Enterococcus faecium MC-5 isolated from the fish gut was cultured in the MRS broth to produce exopolysaccharide (EPS). The maximum EPS production was optimized using Response Surface Methodology (RSM) with three different factors which include sucrose, ammonium nitrate and pH. RSM result predicted that maximum EPS (16.48 g/L)...

The present work is carried out to determine the biodegradation potential of n-hexadecane by bacterial strain P. aeruginosa PU1 isolated from soil polluted with transformer oil. The bacteria showed its ability to grow in n-hexadecane containing medium and its utilization was revealed by a 2, 6-dichlorophenol indophenol assay, where complete decolou...

Biosurfactant-producing bacteria were isolated from transformer oil-contaminated soil. The strain was identified as Pseudomonas aeruginosa PU1 based on its molecular characterization by 16S rRNA gene sequencing. The extraction of biosurfactant was done by acid precipitation method using 2 N hydrochloric acid and further purified by silica-gel colum...

This study was conducted to evaluate the probiotic potential of Weissella confusa MD1 and Weissella cibaria MD2 isolated from a fermented batter. They possessed characters like high survivability in gastrointestinal conditions, tolerance towards lysozyme and phenol. Both strains exhibited strong auto-aggregation property and co-aggregation with Lis...

The present study focused on production, optimization and characterization of exopolysaccharide (EPS) from Weissella confusa MD1. The purified EPS MD1 was also evaluated for in vitro biological activities. The maximum yield of EPS (10.07 ± 0.32 g/L) was obtained with optimized culture conditions of 35 ˚C at pH 6.5 for 36 h with 4% (w/v) galactose a...

The present study was aimed to examine the concentration of heavy metals in the two edible fish species Carassius carassius and Triplophysa kashmirensis of the Dal Lake (Srinagar, Jammu, and Kashmir, India). Metals cadmium (Cd), manganese (Mn), copper (Cu), zinc (Zn), lead (Pb), and chromium (Cr) were analyzed using atomic absorption spectroscopy (...
