conclusions b. subtilis entrapped in beads was able to preserve its viability and produce biosurfactants as secondary metabolites. therefore, this method could be applied as a continuous culture system of biosurfactant production. methods alginate and bacterial solutions were mixed by stirring to obtain a uniform mixture and added by drops into cacl2 solution to form spherical beads. the spheri...

horseradish peroxidase was encapsulated in calcium alginate for the purpose of phenol removal. considering enzyme encapsulation efficiency, retention activity and enzyme leakage of the capsules, the best gelation condition was found to be 1 % w/v of sodium alginate solution and 5.5 % w/v of calcium chloride hexahydrate. upon immobilization, ph profile of enzyme activity changes as it shows high...

Encapsulation has received considerable interest in the context of object-oriented programming. In particular the encapsulation of objects that are composed through inheritance has been discussed repeatedly [Snyder 86, Micallef 88]. Aspect-oriented composition has similar considerations. However, most approaches to aspect-orientation or multi-dimensional composition of concerns do not enforce e...

A high-quality encapsulation process is crucial to ensuring the performance and long-term reliability of photovoltaic (PV) modules. In crystalline Si technology-based modules, poly (ethylene-co-vinyl acetate) (EVA) is the most widely used PV encapsulant. Its encapsulation process is usually performed in a flat-bed vacuum bag laminator. In certain types of laminators, cooling press can be applie...

phenol is a common pollutant that was listed by us environmental protection agency (epa) among the priority pollutants. classical methods employed for phenol removal are either costly or limited to large-scale applications such as biological and thermal decomposition methods. in this study, adsorption of phenol by a type of clay that is extracted from a local soil called khoweldi was investigat...

the aim of this study was to investigate the effect of the addition of commercial lipase in various forms on the acceleration of the ripening of uf-feta cheese. commercial lipase from aspergillus niger was encapsulated by using silica composition based on sol-gel method. lipase was then added to cheeses in three forms, namely, free lipase, encapsulated lipase, and encapsulated lipase with arabi...

abstract: this study was aimed at probiotication of tomato and carrot juices using lactobacillus plantarum, lb. fermentum, lb. casei, lysinibacillus sphaericus and saccharomyces boulardii. to enhance the stability, the probiotic cultures were micro-encapsulated using alginate coated chitosan beads. tomato and carrot juice samples were pasteurized for 20 min at 63 °c. lb. fermentum, lb. plantara...

Encapsulation mechanisms in object-oriented languages have traditionally been based on static type systems. As a consequence, dynamically-typed languages have only limited support for encapsulation. This is surprising, considering that encapsulation is one of the most fundamental and important concepts behind object-oriented programming and that it is essential for writing programs that are mai...

saffron essential oil has a pleasant aroma and medicinal activities. however, it is sensible into the environmental condition. therefore, it should be protected against unwanted changes during storage or processing. encapsulation is introduced as a process by which liable materials are protected from unwanted changes. in the present study, different ratios (0:100, 25:75, 50:50, 75:25, and 100:0...

ABSTARCT Encapsulation is a process of enclosing the substances within an inert material which protects from environment as well as control drug release. Recently, two type of encapsulation has been performed in several research. Nanoencapsulation is the coating of various substances within another material at sizes on the nano scale. Microencapsulation is similar to nanoencapsulation aside fro...
