Structure and Reproduction of Bacteria

Bacterial Reproduction: This Salmonella bacterium is undergoing the process of binary fission. The cell divides resulting in the formation of two identical cells. Janice Haney Carr/CDC Bacteria are prokaryotic organisms that reproduce asexually. Bacterial reproduction most commonly occurs by a kind of cell division called binary fission. Binary fission involves the…

Bacterial Structures and Functions

Plants host distinct bacterial communities on and inside various plant organs, of which those associated with roots and the leaf surface are best characterized. The phylogenetic composition of these communities is defined by relatively few bacterial phyla, including Actinobacteria, Bacteroidetes, Firmicutes, and Proteobacteria. A synthesis of available data suggests…

Origin of Microorganisms

The discovery of microorganisms raised an intriguing question: Where did these microscopic forms originate? The theory of spontaneous generation suggested that organisms, such as tiny worms, can arise spontaneously from non-living material. It was completely debunked by Francesco Redi, an Italian biologist and physician, at the end of the seventeenth century. By…

Studies Microscopic organisms

Microbiology is the study of microscopic life, or microorganisms, and other associated microscopic nonliving biological particles that interact with living things. The science covers bacteria, fungi, algae, viruses, prions, and many other topics. Although microbes are impossible to see with the naked eye, they have a massive impact in each and every other living thing…

Los Angeles: In a great news for India, scientists at National Aeronautics and Space Administration (NASA) have named a new organism discovered by them after the much-loved A.P.J. Abdul Kalam. Till date, the new organism—a form of a bacteria—has been found only on the International Space Station (ISS) and has not been found on earth! Researchers at the Jet Propulsion…

Microbes that cause disease are called

Food-borne illness often shows itself as flu-like symptoms such as nausea, vomiting, diarrhea, or fever, so many people may not recognize the illness is caused by bacteria or other pathogens on food. Thousands of types of bacteria are naturally present in our environment. Not all bacteria cause disease in humans. For example, some bacteria are used beneficially in…

Table of Microorganisms

Yeasts are unicellular eukaryotic microorganisms isolated from many foods, and are commonly found in table olive processing where they can play a double role. On one hand, these microorganisms can produce spoilage of fruits due to the production of bad odours and flavours, the accumulation of CO2 leading to swollen containers, the clouding of brines, the softening…

Function of Ribosome in Bacterial cells

Ribosomes are small particles, present in large numbers in all the living cells. They are sites of protein synthesis. The ribosome word is derived - ribo from ribonucleic acid and somes from the Greek word soma which means body . The ribosomes link amino acids together in the order that is specified by the messenger RNA molecules. The ribosomes are made up…

Species of Microorganisms

Earth could contain nearly 1 trillion microbial species, with only one-thousandth of 1 percent now identified, a new study suggests. To come up with the estimate, researchers combined microbial, plant, and animal community datasets from government, academic, and citizen science sources. Altogether, these data represent more than 5.6 million microscopic and nonmicroscopic…

Prokaryotic cells Parts and Functions

Prokaryotic cells are simpler and smaller than the eukaryotic cells. The term prokaryote is derived from the Greek word- “prokaryote” meaning before nuclei. These cells lack membrane bound organelles. Prokaryotic cells are unicellular organisms, which reproduce through binary fission. In some cases few prokaryotic organisms also reproduce by budding. Prokaryotic cells…

In recent times diesel powered vehicles are becoming popular due to improved performance and reduced exhaust emission with this the market share of diesel passenger cars expected to approach 60 % over the next few years. In compliance with future emission standards for diesel powered vehicles, it is required to use diesel particulate filters (DPF) along with other…
