MICROORGANISMS USED FOR BIOTECHNOLOGICAL PROCESSES

Both prokaryotic and eukaryotic organisms including plants, animals and microorganisms are used for biotechnological manipulations. Whole animals and plants are manipulated through genetic engineering to produce transgenic animals and plants respectively. In addition, bacteria and other eukaryotic cells have been genetically manipulated to produce non-microbial products such as human growth hormones, insulin, interferon, mammalian proteins […]

MICROBIOTA (NORMAL MICROFLORA) OF LIVING ORGANISMS

DrChika

Microbiota which can also be called normal microflora is the totality of microorganisms that are inherently present in a particular environment, body or location at every specific point of time. Mycoflora are fungal organisms that live in particular sites of the body without causing infection or disease. Microbiota goes into competition with pathogens on and

FOOD PRESERVATION

DrChika

Food preservation is the technique used to prevent food spoilage. It encompass all the methods employed to inhibit or delay the growth of microorganisms especially food spoilage microbes in food and/or food products. Various methods exist for the preservation of food after production and usage. Food preservation amongst other things ensures that the shelf life

SCOPE OF MICROBIOLOGY

DrChika

The field of Microbiology has tremendous possibilities and a very bright future, and intending or prospective students who are seeking or pursuing their career as prospective microbiologist has golden opportunities that await them upon graduation due to their invaluable relevance in virtually all works of life. There are many areas of specialization in microbiology as

HISTORY OF IMMUNOLOGY

DrChika

Man’s interest in achieving some level of resistance to diseases and their causative agents (i.e. immunity) gave impetus to the study of immunology. The field of immunology actually began when it was observed that people who had earlier suffered and recovered from a particular infection or disease were afterwards discovered to have been protected from

HISTORY OF THE MICROSCOPE

DrChika

Before the advent of microscopes and its actual application in viewing and making clear the microbial world which our eyes are not competent enough to see, mankind in time past have been using shiny stones and glasses to view objects; and they discovered that the objects become enlarged when viewed under such objects they termed

HISTORY OF VIROLOGY

DrChika

The field of virology (inclusive of medical virology, plant virology and veterinary virology) blossomed following the discovery and development of transmission electron microscopy (TEM). Virology as a field in the biological sciences has spanned over 200 years; and this important discipline has continued to remain relevant to mankind and its environment owing to the varying

STAINING TECHNIQUE

DrChika

Staining is any microbiological process which increases the contrast of organisms when certain dyes or stains are applied to them prior to their examination under the microscope. It is generally the process of colouring specimens and microorganisms so that they can be easily observed and distinguished under the microscope. Staining in the microbiology laboratory is

MICROBIAL GROWTH PHASE

DrChika

Microbial cells can exhibit different growth patterns depending on the availability of growth nutrients in their immediate environment. In batch culture, microbial cells cannot grow continuously because the growth nutrients required for development is not renewed after it has been depleted. Thus exponential growth is limited to a few generations of microbial cells in batch
