ABSTRACT: Soy protein was enzymatically modified and ultrafiltred, functional properties were evaluated. After enzymatic hydrolysis, hydrolysate (20 g/100 mL) incubated with chymotrypsin glycerol at 37°C. Different methionine methyl‐ester concentrations, pHs, time tested. Amino acid composition of ultrafiltrated fractions (FI>10, 10>FII>3, 3>FII>1 kDa) Optimum hydrolysis conditions 12 h 50°C, those synthesis 0.07585 g Met/g, pH 7, 3 h, binding 2.2% to 5% methionine. Fractions...
Water, surface sediments, the mussel Mytella strigata, mangrove oyster Crassostrea corteziensis, and green macroalgae Caulerpa sertularioides from four locations in Mazatlán Harbor on southeast coast of Gulf California, were analyzed to determine concentrations distribution patterns cadmium, copper, mercury, lead, zinc. Total metal water present study exceed background levels open sea coastal waters. sediments ordered as follows: Zn > Pb Cu Cd Hg, but for bioavailable fraction Hg. The fall...
Abstract Mercury (Hg) transference through an established and defined food web from urbanized subtropical coastal lagoon (SE Gulf of California) was examined by using carbon nitrogen stable isotope Hg analyses. Concentrations in seawater (0.045–0.078 μg L −1 ), predominantly incorporated to the particulate fraction (60% total), were lower than those found highly contaminated areas around world (0.18–16 ). Although levels available for biota (e.g., associated reactive pyrite fractions;...
Abstract This investigation sought to assess the biological responses Pb along a simplified four‐level food chain, from primary producer, microalgae Tetraselmis suecica , grown in control medium with < 1 µg/L of and exposed sublethal dose (20 Pb) used as base simulated through primary‐, secondary‐, tertiary‐level consumers, namely, brine shrimp, Artemia franciscana ; white‐leg Litopenaeus vannamei grunt fish, Haemulon scudderi respectively. Growth Pb‐exposed T. was 40% lower than that...
The purpose of this research is to provide a comprehensive assessment the concentration levels and spatial variability cadmium (Cd), copper (Cu), mercury (Hg), lead (Pb) zinc (Zn) in El Tobari Lagoon surface sediments during two seasons for several geochemical variables that could explain observed heavy metal variability. Seventy-two samples were collected 12 different sites Lagoon. Sediment dried subjected acid extraction using microwave system five metals (Cd, Cu, Hg, Pb Zn) measured...
