1. Microbial Ecology: Fundamentals and Applications (4th Edition) 4th Edition Advertisements by Ronald M. Atlas (Author), Richard Bartha (Author) Staying current in a discipline where advances are defined by methodological developments can be a challenge – that’s why more people choose Microbial Ecology over any other resource available. The fourth edition features enhanced coverage of … Read more
Advertisements From shortly after birth to death, the skin and mucous membranes are home to a diverse microbial fauna. The average human body contains 1013 cells and harbors 1014 bacteria. This is the normal microbial population. The normal microbial fauna is stable. During certain times in a person’s life, specific genera may populate different body … Read more
The process of growing an organism in the surface of a medium is known as culture. The food source that supports the development of the organism is known as a culture medium. The media for culture are designed so that the organism will receive all the nutrition requirements. However, the media for culture are made in laboratories by weighing and dispensing particular ingredients or by purchasing ready-made media on the market. The majority of the media include organic as well as inorganic nutrients. However, to cultivate a variety of microorganisms, special media are created. If the media is to be solidified required, agar-agar can be mixed with other ingredients. The culture media can be classified into three categories that include semi-synthetic, natural and synthetic media each of which is employed for microbiological studies.
It is the science of studying the interactions between light and matter , where the emission and absorption of the light radiations by the material are investigated and assessed. The focus of spectroscopy is the dispersion of light as well as other radiations caused by the object, which allows the examination of the various characteristics that the objects.
The nitrocefin biochemical test is a sensitive technique for detecting beta-lactamase-producing strains of N. gonorrhoeae, H. influenzae, Staphylococcus spp, Enterococcus spp, and Moraxella (Branhamella) catarrhalis. Nitrocefin is the only reliable test for detecting beta-lactamase-producing Enterococcus spp.
Microbiology laboratories require well-built rooms that are equipped with tools, glassware and equipment. Test tubes, culture tubes, Petri dishes and Erlenmeyer flasks are the most important types of glassware in a microbiological lab.
Tris-SDS Buffer (pH 6.8) is used to prepare buffer for stacking gel during SDS-PAGE (SDSPolyacrylamide gel electrophoresis). It is a discontinuous gel with a huge pores size to concentrate proteins prior to entering the separating zone. The buffer is sold in a 5X stock.
Staining protein gels using Coomassie Brilliant Blue R-250 is common to see proteins that are resolved using SDS-PAGE. It is extremely sensitive and suitable for long-term storage of gels.
Electrophoresis with agarose or other polyacrylamide gels is an established method to separate the biopolymers, determine their identity and purify them because both of these gels have a porous the natural world. Polyacrylamide gels are chemically cross-linked gels formed by the polymerization of acrylamide with a cross-linking agent, usually N,N’-methylenebisacrylamide.
The Davson Danielli model (or the paucimolecular model) was an illustration that depicts the membrane in cells. It was developed in the year 1935 by Hugh Davson and James Danielli The model is a bilayer of phospholipids which is located within two layers of protein globular. the model is trilaminar as well as lipoproteinous.
In the context of human beings,”growth” is a reference to the increase in size; as an example changing from a tiny newborn to a huge adult. While bacteria can grow in size prior to the division of cells, growth in bacteria is a term used to describe increasing the amount of organisms, instead of the growth of their size.
mainly due to their ampholytic properties and biochemically mainly because they are protein constituents. An amino acid is a carboxylic acids that contain an aliphatic primary ammonium group in the same position as the carboxyl group. It also has a distinctive stereochemistry. Biosynthesis of proteins is done using 20 amino acids, which are subject to strict genetic control.
Bacillus cereus, a pathogenic, food-borne disease-causing organism, is widely distributed in nature, such as on plants, soils and the GI tracts and mammals of insects and other mammals.
Advertisements In this article, we will learn about the Membrane filtration methods, definition, applications, advantages, disadvantages. Before heading towards Membrane Filtration, you have to understand what is filtration? Membrane filtration is a method of separating particles or molecules from a liquid or gas stream using a semi-permeable membrane. The membrane acts as a barrier, allowing … Read more
