Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Le chitosane est préparé à partir de carapaces de crevettes à l'aide de méthodes de bioconversion, par opposition à la méthode de traitement chimique. Les propriétés physicochimiques, le poids moléculaire, le degré de désacétylation, la teneur en cendres ainsi que le rendement du chitosane préparé indiquent que la bioconversion est une méthode efficace et durable pour l'isolation du chitosane. La chitine désacétylase, l'enzyme qui catalyse l'hydrolyse des groupes acétamido de la N-acétylglucosamine dans la chitine, a été purifiée jusqu'à homogénéité à partir de la bactérie Bacillus altitudinus et caractérisée plus en détail. La chitine désacétylase est active sur plusieurs substrats chitineux et dérivés de la chitine. L'enzyme est inhibée par 1 mM de Hg2,Fe2+, mais l'ajout de Mn2+ augmente légèrement l'activité de la chitinase. Lorsque la chitine colloïdale (un dérivé de la chitine) a été utilisée comme substrat, la température et le pH optimaux pour l'activité enzymatique ont été déterminés. La morphologie de surface du chitosane traité et la masse moléculaire apparente de l'enzyme ont été déterminées respectivement par microscopie électronique à balayage (MEB) et par électrophorèse sur gel de polyacrylamide au dodécylsulfate de sodium (SDSPAGE). …

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Chitosan wird aus Garnelenschalen unter Verwendung von Biokonversionsverfahren im Gegensatz zu chemischen Behandlungsverfahren hergestellt. Die physikalisch-chemischen Eigenschaften, das Molekulargewicht, der Deacetylierungsgrad, der Aschegehalt sowie die Ausbeute des hergestellten Chitosans zeigen, dass die Biokonversion ein gutes und nachhaltiges Verfahren zur Isolierung von Chitosan ist. Chitin-Deacetylase, das Enzym, das die Hydrolyse der Acetamidogruppen von N-Acetylglucosamin in Chitin katalysiert, wurde aus dem Bakterium Bacillus altitudinus bis zur Homogenität gereinigt und weiter charakterisiert. Chitin-Deacetylase ist auf mehreren chitinhaltigen Substraten und Chitinderivaten aktiv. Das Enzym wird durch 1 mM Hg2,Fe2+ gehemmt, aber die Zugabe von Mn2+ erhöht die Chitinaseaktivität leicht. Bei Verwendung von kolloidalem Chitin (einem Chitinderivat) als Substrat wurden die optimale Temperatur und der optimale pH-Wert für die Enzymaktivität bestimmt. Die Oberflächenmorphologie des behandelten Chitosans und die scheinbare Molekülmasse des Enzyms wurden mittels Rasterelektronenmikroskop (REM) bzw. Natriumdodecylsulfat-Polyacrylamid-Gelelektrophorese (SDSPAGE) bestimmt. …

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Il chitosano viene preparato dal guscio dei gamberetti utilizzando metodi di bioconversione rispetto al metodo di trattamento chimico. Le proprietà fisico-chimiche, il peso molecolare, il grado di deacetilazione, il contenuto di ceneri e la resa del chitosano preparato indicano che la bioconversione è un metodo valido e sostenibile per l'isolamento del chitosano. La chitina deacetilasi, l'enzima che catalizza l'idrolisi dei gruppi acetamido della N-acetilglucosamina nella chitina, è stata purificata fino a omogeneità dal batterio Bacillus altitudinus e ulteriormente caratterizzata. La chitina deacetilasi è attiva su diversi substrati chitinosi e derivati della chitina. L'enzima è inibito da 1 mM di Hg2,Fe2+, ma l'aggiunta di Mn2+ aumenta leggermente l'attività della chitinasi. Quando è stata utilizzata come substrato la chitina colloidale (un derivato della chitina), sono stati determinati la temperatura e il pH ottimali per l'attività enzimatica. La morfologia superficiale del chitosano trattato e la massa molecolare apparente dell'enzima sono state determinate rispettivamente mediante microscopio elettronico a scansione (SEM) ed elettroforesi su gel di poliacrilammide con sodio dodecil solfato (SDSPAGE).…
