Context Seaweeds from the Mexican Pacific Ocean have not been evaluated as a source of chemoprotectants. Objective The objective this study is to evaluate chemopreventive activities seaweeds Phaephyceae - Padina durvillaei (Dictyotaceae) Rodhophyceae Spyridia filamentosa (Spyridiaceae), Gracilaria vermiculophylla (Gracilariaceae) and Chlorophyceae Ulva expansa (Ulvaceae), Codium isabelae (Codiaceae), Rhizoclonium riparium (Cladophoraceae) Caulerpa sertularioides (Caulerpaceae). Materials...
Aqueous seaweed extracts have diverse compounds such as Plant-Growth Regulators (PGRs) which been utilized in agricultural practices for increasing crop productivity. Algal biomass of Padina durvillaei and Ulva lactuca suggested use biofertilizers because plant growth-enhancing properties. This work aimed to identify the main PGRs antioxidant properties P. U. extracts, abscisic acid, auxins, cytokinins, gibberellins, jasmonates, salicylates, assess their potential that improve growth yield....
The fruit, vegetable, legume, and cereal industries generate many wastes, representing an environmental pollution problem. However, these wastes are a rich source of antioxidant molecules such as terpenes, phenolic compounds, phytosterols, bioactive peptides with potential applications mainly in the food pharmaceutical industries, they exhibit multiple biological properties including antidiabetic, anti-obesity, antihypertensive, anticancer, antibacterial properties. aforementioned has...
Biochemical composition was assessed in green (Ulva expansa, Caulerpa sertularioides, Rhizoclonium riparium, Codium isabelae), red (Spyridia filamentosa, Gracilaria vermiculophylla), and brown (Padina durvillaei) seaweeds collected from different tropical lagoons on the Pacific coast of Sinaloa, Mexico. Protein content higher C. S. G. vermiculophylla (10–12%), followed by R. P. durvillaei, U. expansa (8%, 6%, 4%, respectively). Lipid range 0.3–1.5%, with highest value found riparium. The...
Agave tequilana Weber azul variety is a valuable source of fructans. In this study, response surface methodology was employed to optimize the extraction yield fructans from agave pines. A Box Behnken factorial design applied evaluate effects several conditions such as temperature, water raw material ratio and time on yield. Under optimum (extraction temperature 79.1 °C, 5.13 mL/g, 1.48 h) 83.12%. The chromatographic profile crude extract presented four peaks, out which were most preponderant...
Mutations are the result of effects produced by mutagenic agents, which may be responsible for generation chronic-degenerative diseases such as cancer. The aim this work was to detect and characterize compounds with antimutagenic activity in white shrimp (Litopenaeus vannamei) cephalothorax. A serial extraction carried out where different organic solvents, its biological evaluated. antioxidant capacity evaluated DPPH ABTS assay, methanol water-soluble extracts had highest capacity....
Pacific thread herring (Ophistonema libertate) muscle was hydrolyzed with Alcalase for the preparation of protein hydrolysates. The effect enzyme concentration (EC; 1% and 3%), pH (8 9) temperature (40°C 50°C) on some biochemical properties antioxidant activity (AOXA) determined. degree hydrolysis (DH) ranged between 9.6% 33.1%. highest DH obtained following conditons: EC 3%, 9 50°C; however, AOXA measured by DPPH (183.7 µmol TE/mg), FRAP (0.98 ABTS (144.9 TE/mg) at 8 50°C. These also...
Abstract: Using different stereoselective chemical and chemoenzymatic approaches we synthesized the chiral, C α ‐methylated α‐amino acid l ‐(αMe)Nva with a short, linear side‐chain. A set of terminally protected model peptides to pentamer level containing either (αMe)Nva or Nva in combination Ala and/or Aib was prepared using solution methods characterized fully. Two were also side‐chain hydrogenation corresponding ‐methyl, ‐allylglycine (Mag) peptides. detailed crystal‐state conformational...
Summary An aminopeptidase (AP) was partially purified from jumbo squid ( Dosidicus gigas ) hepatopancreas with 154.24‐fold and yield of 6.15%. The purification procedure consisted ammonium sulphate fractionation DEAE‐Sephacel chromatography. enzyme approximately 48–53 kDa as estimated by SDS‐PAGE. With l ‐leu‐ p ‐NA, it had optimum activity at pH 8.0 30 °C. K m V max / values the enzymes for ‐NA were 0.326 2787 37 °C, respectively. Activation energy E a 53.50 kJ M −1 .The AP showed against...
This work looks at the antibacterial efficacy of Gracilaria vermiculophylla and Ulva flexuosa aqueous extracts when added to feed Penaeus vannamei in an experimental infection with Vibrio parahaemolyticus (M0904AHPND+strain). Results show that minimum inhibitory concentration (MIC) for both was 50 mg mL-1, inhibition zones 18.00 ± 0.60 mm G. 14.00 0.29 U. flexuosa. gave a higher total content phenolic compounds (10.58 2.31 GAE g-1) (gallic acid equivalent) lower flavonoid (10.32 0.73 QE...
Plants represent an attractive source of milk-clotting proteases with potential use for chymosin substitution in cheesemaking process. A crude enzymatic extract from B. pinguin fruit showed capacity to clot milk efficiently a short time. It maximum activity around 4 U/mL the range 70-80 ºC. This value indicated that one mL was capable 400 40 min at specified condition. presented only 25% its under standard temperature (30-35 ºC) cheese-making. Proteases inhibitors cysteine and serine were...
The objective of the research was to evaluate in vitro and vivo antibacterial efficacy Rhizophora mangle Laguncularia racemose when added feed Penaeus vannamei an experimental infection with Vibrio harveyi (CAIM 1792) V. campbellii 333). Results show that minimum inhibitory concentration for both extracts 1.65 g mL-1, inhibition zone 25 ± 1 mm (V. campbellii); 18 2 harveyi) L. 21 20 R. mangle. gave a higher total content phenolic compounds (4.50 0.26 mg GAE mL-1) flavonoids (2.60 0.15 QE...
