Journal PapersISFJ , Volume 29 , Issue 6, 2021 February 10, {Pages 167-178 }

Abstract

Alginate is one of the unique polysaccharides present in brown algae which are widely used in textile, paper, and food, pharmaceutical, biomedical and cosmetic industries. There are many seaweed species in the southern coast of our country (Iran). However, very few studies have been done so far on the extraction of alginate from these indigenous resources. Therefore, in the present study, alginate was extracted and purified from a brown seaweed Sargassum ilicifolium. Then, yield, molecular weight, antioxidant activity (DPPH radical scavenging activity and reducing power (FRAP), and emulsifying properties (emulsification indices) of the isolated alginate were evaluated. Furthermore, FT-IR spectra were used to identify the functional groups o

Abstract

The effects of alkaline and acid solubilization pHs (11, 11.5, 3.5 and 2.5) combined with ultrasonication (100, and 400?W for 0, 5, 10 and 20?min) on protein recovery from rainbow trout by-product and its structural and functional properties were investigated. The combination of pH-shift processing with ultrasonication increased protein solubilization and total yield compared with the classic pH-shift processing. The combination also significantly reduced particle size, tryptophan fluorescence intensity, and reactive sulfhydryl groups content of the protein isolates. The secondary structure of the proteins was also influenced by ultrasonication with decreasing in α-helix and increasing in β-sheet, β-turn and random coil content. However,

Abstract

Antioxidant activity of Klunzinger's mullet (Liza klunzingeri) muscle hydrolysates obtained using Bacillus licheniformis fermentation and enzymatic hydrolysis was determined. Hydrolysates obtained after 6 days of fermentation with B. licheniformis showed the highest free radical scavenging activity, metal chelating ability and ferric reducing antioxidant power (FRAP) (P ≤ 0.05). Microbial fermentation led to a higher percentage of small peptides and higher solubility compared with Alcalase hydrolysis (P ≤ 0.05). Hydrolysates showing the highest antioxidant properties attenuated serum, liver, and kidney oxidative stress biomarkers in male Wister rats stressed by carbon tetrachloride (P ≤ 0.05). At 300 mg/kg oral administration, hyd

Abstract

Polysaccharides from Nizamuddinia zanardinii were extracted using water at elevated temperature and fractionated by a DEAE Sepharose FF column yielding four fractions (F1-F4). Crude and fractions were composed of neutral sugars (50.8–57.4%), proteins (10.8–18.1%), sulfates (7.5–17.3%) and uronic acids (3.5–7.7%). Various levels of galactose (13.4–44.4%), fucose (34.1–40.1%), mannose (14.1–33.2%) and xylose (7.4–15.2%) formed the building blocks of the polysaccharide structures. The weight average molecular weights (Mw) of polysaccharides varied between 40.3 and 1254.4?× 103?g/mol. F3 polysaccharide was the most active fraction stimulating RAW264.7 murine macrophage cells to secrete NO, TNF-α, IL-1β and IL-6, and activati

Abstract

In this research, the propane steam reforming (PSR) as a promising alternative route over a mesoporous NiO–MgO–SiO2 catalyst to produce syngas (SG) was undertaken. This catalyst was prepared using a co-precipitation method followed by hydrothermal treatment. The influence of such catalyst preparation factors as the hydrothermal time and temperature, pH and calcination temperature on the physicochemical characteristics of the prepared samples were examined. Next, these materials were characterized through the BET-BJH, XRD, TPR, and FTIR analyses. The thermal stability of this catalyst was tested through the TGA and DTA techniques. Furthermore, the deactivation of the calcined catalysts at different temperatures was investigated via the T

Abstract

Many bacteria including Escherichia coli can enter into the viable but non‐culturable (VBNC) state under unfavorable condition. This study investigated the fate of E. coli O157:H7 under high salinity stress in salted silver carp. E. coli O157:H7 was inoculated in distilled water and fish meat under 0, 10, and 30% NaCl at room temperature. The culturability of bacteria was investigated using culture‐based colony counting method. Viability and expression of pathogenic genes of E. coli O157:H7 were evaluated using reverse transcription polymerase chain reaction (RT‐PCR) of 16S rRNA, stx1, stx2, eae, and hly genes. The bacteria kept their culturability in both water microcosms and fish meat without salinity stress, however, bacterial cul

Abstract

This study was carried out to evaluate the effect of the various gamma dose irradiations on the antioxidant activity of rosemary PBS (phosphate-buffered saline) extract. The PBS extract of rosemary was irradiated with gamma rays at the doses of 10, 20, 30, 40 and 50 kGy, and their antioxidant activities were investigated by DPPH (1,1-diphenyl-2-picrylhydrazyl), radical cation ABTS•+ (2,2-Azino-Bis (3-Ethylbenzthiazoline-6-Sulfonic Acid), Diammonium Salt), ferric reducing antioxidant power assay (FRAP) and ferric chelating capacity using ferrozine. The scavenging activities of gamma irradiated rosemary were observed to be significantly higher at 30 and 40 kGy using both methods, DPPH and ABST. Also, the reducing power values of 30 kGy gamm

Abstract

Diabetes mellitus is a major health problem in the worldwide. Inhibition of DPP-IV is one of the methods to control diabetes type 2. Inhibition of this enzyme may improve glycemic control in diabetics by preventing the rapid breakdown and there by prolonging the physiological action of incretin hormones. Furthermore, improving the antioxidant system in diabetic patients can prevent the occurrence of secondary disease caused by oxidative stress. Therefore, the head of skipjack tuna was hydrolyzed with alcalase enzyme (1/5% of raw material weight) for 4 hours, in order to produce a product with antidiabetic and antioxidant activities. The DPP-IV inhibition activity, DPPH radical scavenging activity and reducing power of hydrolysate were measu

Abstract

This study aimed to evaluate the fate of Listeria monocytogenes in water microcosm and rainbow trout fillet under salinity stress of 0% and 30% NaCl at refrigerator temperature (4 ? 2 ℃). Bacterial culturability was studied by standard culture and colony count method. Reverse transcription-PCR (RT-PCR) of 16 S rRNA gene was used to detect viability of non-culturable bacteria. Also, the qualitative expression of pathogenic genes (hly and inlA) was studied using RT-PCR. The results showed that bacteria in water microcosm lost their culturability at 13 days under 0% salinity (starvation or distilled water) and at 27 days under 30% salinity; however, bacteria in rainbow trout fillet remained culturable under 0% and 30% NaCl.
