Membrane Processing MEMBRANEFILTRATION A membrane or‚ more properly‚ a semipermeable membrane‚ is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Membrane filtration enables to separate particles with a diameter smaller than the pore diameter in the membrane from the liquid feed‚ by applying a driving force (pressure) over the membrane. The membrane technology consists principally of Microfiltration (MF)‚ Ultrafiltration

Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing. The results of the exercise or experiment are what are being showcased‚ not the writing. The purpose of scientific writing is not to entertain‚ but to inform. The writing should be simple and easy to understand. There is a specific style that must be followed when writing scientific reports. Scientific writing is typically written in the passive voice. The

Lactase splits milk-sugar lactose into glucose and galactose. This process is used for milk products that are consumed by lactose intolerant consumers. Addition of pectinase‚ xylanase and cellulase improve the liberation of the juice from pulp. Similarly enzymes are widely used in wine production. 4. Textiles The use of

Semiconservative replication produces two copies that each contained one of the original strands and one entirely new strand. d. Topoisomerases catalyze and guide the unknotting of DNA e. Single Strand Binding Proteins attach to the halves and keep the DNA molecules separated (they are needed because the sides are attracted to each other and with out

Review of Literature The question being asked here would be “Does a plant grow bigger if watered with milk? Or water?” In my opinion the answer would be milk because milk contains vitamins and calcium that water does not have‚ but the answer is to be found out later during the project. Well‚ it is known that for a plant to survive it will definitely need air‚ soil‚ water‚ light‚ and space to grow‚ but maybe if we replaced water with milk‚ plants could grow bigger and quicker‚ you never

Enterobacteriaceae family. It is a small gram-negative Rod‚ and a facultative anaerobe‚ lastly‚ it is a Prokaryote. Furthermore‚ Proteus mirabilis is characterized by its swarming motility‚ its ability to ferment maltose‚ and its inability to ferment lactose. P. mirabilis has the ability to elongate itself and secrete a polysaccharide when in contact with solid surfaces‚ making it extremely motile on items such as medical equipment (catheters). Moreover‚ Proteus mirabilis is part of the normal flora of
