Amilases

sales with its major application in the starch industry as well as its well-known usage in bakery. With the advent of new frontiers in biotechnology, the spectrum of a-amylase application has also expanded to medicinal and analytical chemistry as well as in automatic dishwashing detergents, textile desizing and the pulp and paper industry. Amylases are of ubiquitous occurrence, produced by plants, animals and microorganisms. However, microbial sources are the most preferred one for large scale production. Today a large number of microbial a-amylases are marketed with applications in different industrial sectors. This review focuses on the microbial amylases and their application with a biotechnological perspective. # 2003 Elsevier Science Ltd. All rights reserved.

Introduction Amylases are enzymes which hydrolyse starch molecules to give diverse products including dextrins and progressively smaller polymers composed of glucose units [1]. These enzymes are of great significance in present day biotechnology with applications ranging from food, fermentation, textile to paper industries [2]. Although amylases can be derived from several sources, including plants, animals and microorganisms, microbial enzymes generally meet industrial demands. Today a large number of microbial amylases are available commercially and they have almost completely replaced chemical hydrolysis of starch…

work were developed three environmentally friendly analytical methods for quantification of bumetanide. The first method developed was diffuse reflectance spectroscopy using spot test analysis. The method is based on the reaction between bumetanide and colored reagent p-dimethylaminocinnamaldeyde (p-DAC – 3.4 x 10-2 mol L-1) in acid medium (HCl – 2.1 x 10-1 mol L-1) on the surface of filter paper, yielding a stable colored product (λ = 525 nm). For the reaction only 20 µL of reagent…

movimentavam cerca de uS$ 2 trilhões. Inaugurava-se, nessa época, a terceira e mais recente geração de fundos SrI: os chamados best in class. Esses fundos não aplicavam a exclusão sumária de setores considerados polêmicos ou de alto impacto ambiental, nem concentravam suas carteiras em empresas de tecnologia limpa. Seus administradores definiam as carteiras avaliando as empresas por meio de critérios ambientais, sociais e de governança, ampliando o leque de análise dos impactos das…

withdraw and we will not be able to get anything out of them. On the contrary, each one must feel individualized, each must have the impression that he is being looked at, that he is being addressed personally. Only then will he respond and cease to be anonymous (although in reality remaining anonymous). Thus all modem propaganda profits from the structure of the mass, but exploits the individual's need for self-affirmation; and the two actions must be conducted jointly, simultaneously.…

guidelines in a number of areas. This is important, because software developers who simply only follow (for example) ISO 17799 will generally not produce secure software − developers need much, much, much more detail than ISO 17799 provides. The Commonly Accepted Security Practices & Recommendations (CASPR) project at http://www.caspr.org is trying to distill information security knowledge into a series of papers available to all (under the GNU FDL license, so that future document…
