Soil Microorganisms Bacteria

Amongst the different microorganisms inhabiting in the soil, bacteria are the most abundant and predominant organisms. These are primitive, prokaryotic, microscopic and unicellular microorganisms without chlorophyll. Morphologically, soil bacteria are divided into three groups viz Cocci (round/spherical), (rod-shaped) and Spirilla I Spirllum (cells with long…

Organelles Include

Organelles Include

In cell biology, an organelle is a specialized structure within a cell that performs a specific function and that generally is considered to be separately enclosed within its own lipid membrane. For example, the nucleus of a cell is an organelle that maintains the integrity of genes and controls cell activity by regulating gene expression. Lysosomes are organelles…

MycoWorks mushroom leather. Credit: Science Friday As it stands, the mushroom is a pretty multi-purpose organism: Aside from its ecological functions, it can be eaten as nourishment, brewed as tea, taken as a naturopathic remedy, and used in dyes. But a San Francisco start-up by the name of MycoWorks has even more plans for mushrooms, starting with a leather-like…

What are the Different Types of microbes?

Propionibacterium acnes bacteria are found deep in the hair follicles and pores of the skin, where they usually causes no problems. However, if there is an over-production of sebaceous oil, they grow, producing enzymes that damage the skin and cause acne. Credit: SCIENCE PHOTO LIBRARY/Getty Images Propionibacterium acnes thrive on the oily surfaces of the skin…

Prokaryotic cell Nucleoid

Prokaryotic cell Nucleoid

The nucleoid is an irregularly-shaped region within the cell of a prokaryote that contains all or most of the genetic material. Learning Objective Evaluate the nucleoid in prokaryotes Key Points The genome of prokaryotic organisms generally is a circular, double-stranded piece of DNA, multiple copies of which may exist at any time. The length of a genome varies…

Bacterial cell Labeled Diagram

One of the first things you learn once you start taking biology as a subject is that life is split into two separate domains - prokeryotes and eukaryotes. Prokaryotes are small and blobby and have no nucleus or internal organisation, while eukaryotes are big and multicellular and contain not just a nucleus, but all sorts of other organelles inside the cell such…

Bacterial Organelles

Researchers at Berkeley Lab and MSU have obtained the first atomic-level view of an intact bacterial microcompartment, shown here. Credit: Markus Sutter/Berkeley Lab and MSU Scientists are providing the clearest view yet of an intact bacterial microcompartment, revealing at atomic-level resolution the structure and assembly of the organelle s protein shell. The…

Role of humus in soil

Role of humus in soil

What sounds like a healthy dip and is good for soil fertility? The unexpected answer is: humus. While for many hummus is the ultimate dip, humus is the ultimate organic soil. Humus, which literally means “earth” and “ground” in Latin, is made from decomposed plants and other organic materials¹. Because of its high ratio in organic compounds, humus is also very…

Meaning of Micro organisms

She said that despite these tests, the precise microorganism cannot be identified in up to half of the people who have pneumonia and when the person is severely ill and is not helped by initial therapy and doctors can try to obtain better samples, often by inserting a long flexible tube (bronchoscope) into the airways.The effective microorganism enhances the…

Types of Microbes in soil

RELATIVE AMOUNTS OF BACTERIA AND FUNGI All soils contain both bacteria and fungi, but they may have different relative amounts depending on soil conditions. The general ways in which you manage your soil—the amount of disturbance, the degree of acidity permitted, and the types of residues added—will determine the relative abundance of these two major groups of…

Flagella in an Animal cells

It s time to discuss our very own special set of cellular goods. Centrioles The centriole is a small, barrel-shaped tube composed of protein located in the cytoplasm. Barrels of fun: The centriole s main function is to aid in cell division and in the spatial arrangement of structures within the cell. Less is known about the function of centrioles than many of…

Composition of Bacterial cell wall

Some general properties of the cell walls of four Gram-positive and two Gram-negative bacteria have been studied. The rate of hydrolysis of cell walls of several bacteria, by 2 N HCl at 100° C, has been followed by estimation of liberated reducing substances and hexosamine. Several extraction procedures have been used in a study of the lipid content of the cell…

Bacterial cells are

In a surprise discovery, scientists have found that bacteria see the world in effectively the same way as humans, with bacterial cells acting as the equivalent of microscopic eyeballs. British and German researchers made the finding by accident when studying aquatic cyanobacteria, which sometimes form a green film on rocks and pebbles. Scientists already knew…

Groups of Micro Organism

A. INTRODUCTION TO MICROBIOLOGY Fundamental Statements for this Learning Object: 1. Microorganisms are typically too small to be seen with the naked eye. 2. Bacteria, fungi, viruses, protozoa, and algae are the major groups of microorganisms. 3. The vast majority of microorganisms are not harmful but rather beneficial. 4. Microbiota refers to all of the microorganisms…

List of Microscopic organisms

Main Image: A microorganism or microbe is an organism that is unicellular or lives in a colony of cellular organisms. The study of microorganisms is called ‘Microbiology’. Microorganisms live in all parts of the biosphere where there is liquid water, including soil, hot springs, on the ocean floor, high in the atmosphere and deep inside rocks within the Earth…
