BACKGROUND Antimicrobials are used to directly control bacterial infections in pet (ornamental) fish and are routinely added to the water these fish are shipped in to suppress the growth of potential pathogens during transport. METHODOLOGY/PRINCIPAL FINDINGS To assess the potential effects of this sustained selection pressure, 127 Aeromonas spp. isolated from warm and cold water ornamental fi...

A model for volume hologram formation in thick dichromated gelatin fih-ns is given. Using the model and a few basic film measurements, we can quantify the index modulation vs. exposure curve. The effects of saturation and dynamic absorption increase during exposure are considered in the generation of spatial harmonics. The effects of exposure with non-unity beam-ratio and multiple incoherent ex...

1. It has been shown in previous publications that when solutions of different concentrations of salts are separated by collodion-gelatin membranes from water, electrical forces participate in addition to osmotic forces in the transport of water from the side of the water to that of the solution. When the hydrogen ion concentration of the salt solution and of the water on the other side of the ...

Background: Fillet is a popular part of chicken carcass which its high perishability is an economic problem. The present research was designed to study the microbial, chemical, and sensorial properties of chicken fillets coated by gelatin-Carboxymethyl Cellulose (CMC) film containing Essential Oil (EO) of Bene (Pistacia atlantica). Methods: The chicken fillets were coated by gelatin-CMC film c...

protein memories are novel technologies which use the hidden abilities of bacteria proteins and biological molecules in order to the electronic processes. four decades before baceriorhdopsin ( br) protein was extracted from the membrane of halobacerinum salina rum found in high salt water depositions after its original discovery in 1967. in this study, for immobilizing the protein a film has be...

This investigation focused on the role played by cold-insoluble globulin (CIg, plasma fibronectin) in monocyte function. Surface-bound CIg mediated a concentration-dependent of human blood monocytes to gelatin-coated surfaces. CIg also mediated the binding of gelatin-coated particles such as latex beads or tanned erythrocytes to surface-bound human monocytes. However, CIg did not mediate partic...

Preserved eggs are prone to lose water during storage, which causes the preserved shrink and have poor taste, bad flavor, reduced quality. By studying a degradable coating agent applying it eggs, we explored its effect on quality of storage. In this paper, structure performance gelatin film (GF), gelatin–bacterial cellulose (GBF), cellulose–MgO nanocomposite (GBMF) were by adding bacterial (BC)...

This review discusses the latest advances in the composition of gelatin-based edible films and coatings, including nanoparticle addition, and their properties are reviewed along their potential for application in the food packaging industry. Gelatin is an important biopolymer derived from collagen and is extensively used by various industries because of its technological and functional properti...
