Sodium chloride salting-in and microwave irradiation were combined to drive thermolysin molecules into mesoporous support to obtain efficiently immobilized enzyme. When the concentration of sodium chloride was 3 M and microwave power was 40 W, 93.2% of the enzyme was coupled to the support by 3 min, and the maximum specific activity of the immobilized enzyme was 17,925.1 U mg(-1). This was a 4....

a model capable of predicting the minimum content of aflatoxin m1 (afm1) in iranian while brine cheese has been developed using a chemometric approach to determine the optimum processing conditions. renneting temperature, cut size, stirring time, press time, curd size and saturated brine ph were all regarded as process variables. three-dimensional response surface and contour plots were drawn. ...

Duck eggs are an animal food that can be consumed. In community life, generally there two ways of salting, namely the first with water, salt, and bricks. The process mixing water salt still uses manual method, by hand. Salt is a major factor in salting which functions as preservative to prevent spoilage eggs, thereby increasing their shelf life. order become salted general, preservation. method...

The investigation was conducted with methanolic fruit extract of Averrhoa carambola for its antibacterial and cytotoxic activities. Antibacterial activity of the extract was evaluated against various Gram-positive and Gram-negative bacteria using disk diffusion technique. For cytotoxic activity, brine shrimp lethality bioassay was performed to estimate LC50 values. In our preliminary screening,...

Contact experiments have been performed between an onion lamel-lar phase and brine, in the SDS/octanol/brine system. Using video mi-croscopy we have studied the nonequilibrium behaviour of the swelling and dissolution process of onions. Experiments at T = 20 • C and 30 • C showed that temperature has a strong effect on their behaviour. At low temperature onions are observed to diffuse away from...

Objective: To investigate the antifungal, haemolytic and cytotoxic activity of methanol and methanol: chloroform extracts of the marine Mollusks (10 Gastropods, 5 Bivalves, 2 Cephalopods) and 1 Echinoderm. Methods: Crude methanol and methanol: chloroform extracts of the marine Mollusks (10 Gastropods, 5 Bivalves, 2 Cephalopods) and 1 Echinoderm were tested for antifungal activity using disc dif...

The hypocotyl hook of the lettuce (Lactuca sativa cv. Grand Rapids) seedling is stimulated to a high degree of curvature through a synergistic interaction of ethylene and gibberellic acid in the light. Presentation of various inorganic salts to the seedlings caused extensive alteration of the hormone-induced curvatures, with ammonium and sulfate being the most stimulatory of curvature, and pota...
