摘要:

This review deals with isolation techniques and enzymatic assays which are applicable to the study of enzymes occurring in cereals and legumes. In the section of the paper concerned with separation and purification methods, various types of Chromatographic and electrophoretic techniques are described and specific examples are presented. The discussion of assay methods cites selected assay methods suitable for monitoring enzyme activities in plants using natural, synthetic, dye‐labeled or radiolabeled substrates in different technical combinations. Immunochemical assays of enzymes, characterization of antibodies, and practical examples illustrating how these techniques can be used are also presented.

摘要:

Biofilmandbiofoulingrefer to biological deposits on any surface. Biofilms consist of both microbes and their extracellular products, usually polysaccharides. The purpose of biofilm is to protect the microbes from hostile environments or to act as a trap for nutrient acquisition. Biofilm formation causes problems in many branches of industry, such as in industrial water systems and the medical and process industries. Besides causing problems in cleaning and hygiene, biofilm may cause energy losses and blockages in condenser tubes, cooling fill materials, water and wastewater circuits, and heat exchange tubes, and on ship hulls. Biofilm can also present microbial risks due to the release of pathogens from cooling towers or by reducing water quality in drinking water distribution systems. In the medical industry biofilm is referred to asglycocalyxwhen diseases of the lungs or the gastrointestinal or urinary tract are involved.
