Industrial fermentation processes are mostly operated under vigorous aeration, maintaining the supply of sterilised air to the fermenter. Air filters should be attached to air input and exhaust ports for preventing the...
Sterile products are free of microbes, pyrogens, and particulates. They also possess high standards of purity and quality. Therefore, the sterilisation methods used during the manufacturing of sterile products should be evaluated...
Salmonella typhi and Escherichia aerogen bacteria obtain carbon from citrate. This ability of utilizing citrate as the carbon and energy source is used as a distinguishing test for some Grods. Principle Simmons citrate agar...
Transmission electron microscope utilise an electron beam which passes through and interacts with an ultra-thin sample to produce an image, which is then magnified and focused on an imaging device (a fluorescent screen), on a...
Scanning electron microscopy utilises electron beam for producing high-resolution images of sample surfaces. It forms 3-D view of the sample. It also gives the surface topography of the sample with sufficient clarity and depth of...
The term growth in microbiology indicates the magnitude of total population. Microbial growth measurement is essential for: Determining the growth and reproduction rate, Determining the suitability of water, milk, and food for...
In this method, an individual desired cell is picked up from the mixed culture and allowed to grow. For this purpose following two methods are used: Capillary Pipette Method : In this method (figure), a few small drops of a...
Culture is a procedure during which microorganisms are cultivated in a medium; if a culture has the population of a single type of microorganism; it is known as a pure culture. Usually, isolation and growth of pure cultures of...
To cultivate a specific microbe, following methods are used : Methods of Culturing Aerobic Bacteria : An atmosphere having oxygen in ample amount facilitates the growth of aerobic or facultative bacteria. For this, a large...
