Introduction to Environmental Microbiology-Microbes in Terrestrial, Aquatic, ATMO Spheric and Biological Environment Total views (508)  
Environmental microbiology is usually defined as "the study of the applied effects of microorganisms on the environment and on human activity, health and welfare. As biotic component of the ecosystem, the role of microorganisms expanded during recent past, and the interest of microbiologists shifted to discovery and application of new microbes and their products to environment, human health and we ......

Water Borne Diseases, Causes and Remedies, Testing Techniques-Plate Count, MPN and MTFT-Significance of Each Tests Total views (508)  
Disease-causing microorganisms are called pathogens. The organism which is attacked and subsequently becomes diseased is called host. Infection is the process in which microbe multiplies or grows in or on the host and in most cases results into the disease. The time between infection and the appearance of clinical symptoms is the incubation time. The term pathogenicity refers to the ability of a p ......

Viruses: Types, Characteristics and Enumeration Methods as Applied for Drinking Water Total views (505)  
The word "virus" means poison in Latin. 'Viruses are generally small, acellular genetic element containing only a single type of nucleic acid, either DNA or RNA. It has to use the metabolic machinery of a living host in order to reproduce. Viruses are thus genetic parasites that take over the hosts cell metabolism and synthetic machinery. Viruses can replicate or multiply, only inside a living hos ......

Industrial Application of Microbes in Fermentation Process Total views (502)  
Industrial fermentation is the intentional use of fermentation by microorganisms such as bacteria and fungi to make products useful to humans. Fermented products have applications as food as well as in general industry. Man has exploited microorganisms since time immemorial .for the production of various kinds of fermented foods and beverages and for making bread. Large scale industrial cultures o ......

Need for Microbiological Studies: Microbial Flora and Fauna Concern to Environment Scientists and Engineers Total views (500)  
Today we understand that .microorganisms, are found almost everywhere. Microorganisms are indispensable components of our ecosystem. The majority of microorganisms make crucial contributions by helping to maintain the balance of living organisms and chemicals in our environment. Marine and freshwater microorganisms form the basis of the food chain in oceans, lakes, and rivers.

Algae - Classifications, Characteristics and Economic Importance Total views (500)  
The algae (singular, alga) are a group of photosynthetic organisms usually recognized by their larger members, such as seaweeds and kelps and the green stains on soil or on rocks. Phycology or algology is the study of algae, The word phycology is derived from the Greek phykos, meaning seaweed. In habitat, size, and reproductive processes algae are a heterogeneous group. These organisms are ubiquit ......

Problems Causes by Algae and its Control Total views (502)  
Most of the algae are aquatic and are found in fresh water or marine habitat. Therefore, they are related with different aspects of fresh-water or marine pollution. During the favourable season of algal growth, water bodies like lakes, ponds and rivers show so much growth of various species of green algae and golden brown algae that the water becomes turbid, cloudy and yellowish / greenish in colo ......

Water Hyacinth and its Control in Natural Ecosystems Total views (505)  
Eichhornia crassipes (Mart.) Solms-Laubach (Pontederiaceae, water hyacinth) is a free floating aquatic plant, native to the Amazon Basin in South America. It has become widespread and is .considered to be the worst aquatic weed throughout the tropical and subtropical regions of the world; Water hyacinth has been widely introduced throughout North America, Asia, Australia and Africa.

Fungi and Bacteria - Classification, Charactericts, General Controlling Measures Total views (502)  
Characterization, classification and identification are major objectives in all branches of the biological sciences. Classification is a means of bringing order to the bewildering variety of organisms in nature. Once we learn the characteristics of an organism we can compare it with other organisms to discover similarities and differences. The human mind tends to arrange similar things together in ......

Morphology of Bacteria, Spore Formation, Nutritional Requirements of Bacteria Total views (501)  
Bacteria are unicellular, prokaryotic microorganisms that reproduce mainly by binary fission. Bacteria are ubiquitous omnipresent in their distribution. They are found in all the natural habitats i.e. soil, water and ail'. The bacterial cell represents a typical prokaryotic cell. Superficially, bacteria appear to be relatively simple forms of life; in fact, they are sophisticated and highly adapta ......

Morphology of Fungi, Spore Formation, Nutritional Requirements of Fungi Total views (500)  
A fungus is a member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and mold. These organisms are classified as kingdom Fungi (Myceteae).The discipline of biology devoted to the study of fungi is known as mycology (derived from the Greek word mykes meaning mushroom), which is a branch of Microbiology. Fungi grow in almost all environments from tropic to high a ......

Bacterial Growth Curve as Applied to Monad's and Haldane's Equation Total views (507)  
Growth may be defined as the orderly increase in all cellular constituents and results from the biosynthetic and energy generating processes. Growth may result in an increase in a microorganism's size, population number, or both. Bacteria are the dominant form of life on the planet. As a result of high rates of their growth and metabolic activity and their adaptability, they are found almost every ......

Biological Process: Definition of Metabolism, Difference Between Anabolism and Catabolism Total views (503)  
A unifying principle in biology is that life is sustained by the trapping and use of energy, a process made possible by the action of enzymes. Energy is the capacity to do work. Living organisms can perform three major types of work: chemical work, transport work, and mechanical work. Most energy used by living organisms originally comes from sunlight trapped during photosynthesis by photoautotrop ......

Microbial Metabolism of Heavy Metals and Pesticides Total views (502)  
Microbial degradation is the process of breakdown of-generally complex organic pollutants to simpler, smaller products by the activities of microorganisms. These organic pollutants serve as the microbial food source. Complete biodegradation or mineralization involves oxidation of parent compound to form carbon dioxide and water, a process providing both carbon and energy for growth and reproductio ......

Bioconcentration and Biomagnification Total views (506)  
Biodegradable substances are those which can be broken down by microbes into harmless compounds. Conservative or recalcitrant pollutants are unable to be broken down and will build up in 'the soil or marine environment. Conservative pollutants include some pesticides, industrial chemicals such as PCBs (polychlorinated biphenyls) and heavy metals such as tin, lead and mercury.

Biocatalysts and Enzymes-Immobilisation of Whole Cells Total views (507)  
The production of most industrially important chemicals involves catalysis. Catalysis is the change in rate of a chemical reaction due to the participation of a substance called a catalyst. Unlike other reagents that participate in the chemical reaction, a catalyst is not consumed by the reaction itself. Catalysts that speed the reaction are called positive catalysts.
