What Kind of Bacterium Cannot Tolerate oxygen?

Photosynthetic bacteria have been around for longer than the Earth’s atmosphere could sustain human life. It was only recently though that scientists began to unravel the mystery of how these micro-organisms execute the mechanisms of photosynthesis. While scientists still have not been able to put all the pieces of the photosynthetic bacteria puzzle in the right…

Bacterial Chromosomal DNA

Bacterial Chromosomal DNA

To isolate plasmid DNA, you crack your cells open and perform a miniprep, trying hard to avoid contaminating genomic DNA. For genomic DNA, you crack your cells open in a different way and try to isolate as much of the contents as possible. So what’s the difference in the protocols? In this article, we will look at plasmid and genomic DNA extraction, and the ways…

What is a cell Capsule?

What is a cell Capsule?

Many bacterial cells secrete some extracellular material in the form of a capsule or a slime layer. A slime layer is loosely associated with the bacterium and can be easily washed off, whereas a capsule is attached tightly to the bacterium and has definite boundaries. Capsules can be seen under a light microscope by placing the cells in a suspension of . The…

Classes of pathogens

Bloodborne Pathogens: Awareness and Prevention Bloodborne pathogens are infectious microorganisms that are transmitted through the blood when someone’s skin gets cut or pricked by a sharp object that contains traces of contaminated blood. Bloodborne pathogens are dangerous because there is no way to get them out of the bloodstream once they enter a person’s body…

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…

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…

3 Main Types of Microorganisms

Despite sharing the title of microorganisms, the organisms in the three subgroups vary physically and biologically. Fungi include mushrooms and mold, along with smaller single-celled organisms. The fungi group includes the largest organisms of all microbe classes. They play important ecological and biological roles, helping break down and recycle decomposing…

Cell Structure Location and Function

Smooth muscle cells and pericytes, together called mural cells, coordinate numerous vascular functions. Canonically, smooth muscle cells are ring-shaped and cover arterioles with circumferential processes, whereas pericytes extend thin processes that run longitudinally along capillaries. Nearly a century ago, Zimmerman described mural cells with mixed features…

Bacterial cell wall Structure and Function

For bacteria, the structural integrity of its cell wall is of utmost importance for survival, and to this end, a rigid scaffold called peptidoglycan, comprised of sugar molecules and peptides, is synthesized and located outside the cytoplasmic membrane of the cell. Disruption of this peptidoglycan layer has for many years been a prime target for effective antibiotics…

Parts of a Typical Bacterial cell

Living cells are divided into two types - prokaryotic and eukaryotic (sometimes spelled procaryotic and eucaryotic). This division is based on internal complexity. The following interactive animations provide graphic roadmaps to the organization of both of these cell types. Prokaryotic Cell Model For life all cells have basic needs. Cells have diverged in their…

Structure: Like many other protists, the structure of Amoeba proteus is relatively simple. It is a single celled organism that appears transparent and gelatin like – with an arguably “forever” changing shape, with a nucleus and membrane bound organelles (such as food vacuoles, contractile vacuoles, golgi apparatus, mitochondria etc.). As mentionned above, Amoeba…

Facts About Bacterial cell

It turns out, there are more reasons to love bacteria than to fear them — the latest being a the discovery of a new bacteria-based antibiotic that allows scientists to fight infections that kill hundreds of thousands of people each year! But there’s more to bacteria than their antibiotic qualities. Check out these nine facts — some of them may surprise you: This…

Capsule of a cell

Fourteen years ago, during the darkest moments of the “stem-cell wars” pitting American scientists against the White House of George W. Bush, one group of advocates could be counted on to urge research using cells from human embryos: parents of children with type 1 diabetes. Motivated by scientists who told them these cells would lead to amazing cures, they spent…

Bacteria cell Pili

Bacteria cell Pili

Pili-plural for pilus-are hairlike appendages found on the surface of many bacteria. Pili are fragile and need to be constantly replaced. The pili (plural) or pilus (singular)is a biological molecule that is on the surface of many bacteria. It is sometimes described as a hair structure. The term pilus comes from the latin word thread or fiber. All of the pili…

Taxonomic Methods

Heterotrophic flagellates contribute significantly to the matter flux in aquatic and terrestrial ecosystems. Still today their quantification and taxonomic classification bear several problems in field studies, though these methodological problems seem to be increasingly ignored in current ecological studies. Here we describe and test different methods, the live-counting…

Microbe Classification

The Baltimore system of virus classification devised by virologist & Nobel laureate David Baltimore is based on the genomic nature of the viruses. The central theme of Baltimore system of virus classification is ‘all viruses must synthesize positive strand mRNAs from their genomes, in order to produce proteins and replicate themselves’. The precise mechanisms…

Bacterial cell Structures and Functions

KEY CONCEPTS: A cell is the basic unit of life, as we understand it. Whilst the overall workings of all cells are very similar, there is no such thing as the conveniently termed ‘typical cell’ but cells within the two main groups of organisms, the prokaryotes (mainly bacteria) and the eukaryotes (higher animals and plants), have many chemical and physical features…
