MAJOR SCOPE / AREAS OF MICROBIOLOGY

Industrial Microbiology The use of microbes by man to produce beneficial products is an ancient practice that has continued till date. Industrial microbiology is the branch of microbiology that uses microbes to produce industrial products in large quantities. Here, the potentials of microorganisms are harnessed for industrial productions and for other related services. Some microorganisms […]

RESPONSES OF THE IMMUNE SYSTEM

DrChika

The immune system is a complex system which consists of collection of cells, organs, tissues and molecules that work together to protect an organism or animal from disease and invading foreign agent’s (i.e. pathogens). For the immune system to function properly and constantly keep the integrity of the human body intact and free from microbes, it

RESOLUTION AND MAGNIFICATION: THE OPTICS BEHIND THE MICROSCOPE

DrChika

Resolution is the ability of a microscope’s lens to distinguish between (two) small objects that are close together as distinct and separate. It is the ability of a lens system to allow an observer (the microbiologist) to see fine details of different small objects even when they are close together. The resolution (resolving power) of

Characteristics of Viruses

DrChika

WAYS IN WHICH VIRUSES DIFFER FROM OTHER LIVING CELLS Viruses as differ tremendously from other unicellular microorganisms in several ways and these unique features of viruses are as follows: References Acheson N.H (2011). Fundamentals of Molecular Virology. Second edition. John Wiley and Sons Limited, West Sussex, United Kingdom. Alan J. Cann (2005). Principles of Molecular

ASEPTIC TECHNIQUE

DrChika

Aseptic technique refers to all the quality control and precautionary measures taken by microbiologists in the laboratory in order to ensure that all working apparatuses are germ-free. It involves numerous processes taken to reduce or prevent the contamination of microbial cultures, reagents and culture media. Aseptic techniques also include all other precautionary measures taken to

MICROBIAL COUNT: Total Count & Viable Count

DrChika

Viable cell count: Viable cell count gives an estimate of the total number of living cells present in a given volume of a sample. Viable cell count can be determined by automated machines and with the use of counting chambers such as the haemocytometer (Figure 1) in the microbiology laboratory. Haemocytometers are routinely used in

CENTRAL DOGMA (FRAMEWORK) OF MOLECULAR BIOLOGY

DrChika

The central framework of molecular biology otherwise known as the “central dogma” is the starting point for the actual course of movement of genetic information within the cell’s nucleus of an organism. The transfer of genetic information within the cell of an organism (i.e. in the nucleus) from deoxyribonucleic acid (DNA) to ribonucleic acid (RNA)

SHAPES / MORPHOLOGY OF BACTERIA

DrChika

All bacterial cells are extremely infinitesimal (i.e. microscopic), and are never visible to the naked eyes. Bacteria exist in different sizes and shapes which may range from 0.1 µm to 0.3 µm wide and 1 µm to 10 µm in length depending on whether they are rod or spherical in shape (Figure 1). Bacteria occur

MICROBIAL METABOLITES: Primary Metabolites & Secondary Metabolites

DrChika

Microbial metabolites are metabolic intermediate molecules synthesized by microorganisms during and after their growth. They are the metabolic intermediates of the biosynthetic and degradative pathways of microorganisms Microbes synthesize metabolites or metabolic intermediates at an increasing rate; and these metabolites are usually harvested or recovered by industrial processes usually at the end of the fermentation

SLIDE RACK & STAINING RACK

DrChika

Slide rack is a piece of vessel used for packing and storing clean glass slides after they have been used for staining. After staining, it is important to wash the glass slides with soap/detergents under running water. The washed glass slides are carefully inserted into the slide rack (Figure 1) where the excess water on
