Types of Microbes

Three different generations (Gen-I, -II and -) of microbial fuel cell (MFC), distinguished by their historical development and mechanisms of electron transfer, were compared. Gen-I utilised synthetic redox mediators combined with Escherichia coli . In contrast, the Gen-II exemplar utilised the natural mediating properties of sulphate/sulphide with the sulphate…

Big Microbes

The name microbe suggests creatures that are so tiny you need a microscope to see them. For most microbes this is true, but there are some gargantuan microbes that we can actually see with the unaided eye. On this page, you’ll read about the biggest of the big in each of the main categories of microbes: viruses, bacteria, protists, fungi and, as an extra added…

Morphology of Microbes

Morphology of Microbes

Students should examine cultures in containers, which have been taped and closed. Colony morphology is a method that scientists use to describe the characteristics of an individual colony of bacteria growing on agar in a Petri dish. It can be used to help to identify them. A swab from a bin spread directly onto nutrient agar. Colonies differ in their shape, size…

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…

Microbes Are Everywhere

Microbes Are Everywhere

Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point, hundreds of millions of years before dinosaurs roamed the earth. Without microbes…

Where can Microbes be found?

Bacteria can be found virtually everywhere. They are in the air, the soil, and water, and in and on plants and animals, including us. A single teaspoon of topsoil contains about a billion bacterial cells (and about 120, fungal cells and some 25, algal cells). The human mouth is home to more than 500 species of bacteria. Some bacteria (along with archaea) thrive…

Examples of Microbes

This leaflet gives a brief overview of the different types of germs (microbes) that can cause infections and a brief overview of the use of antibiotic medication. What are microbes? Healthcare professionals classify germs (microbes) into different groups. The most common groups of microbes that cause illness are described below. Bacteria There are many different…

Microbes are

As the CosmosID blog illustrates regularly, microbes are remarkable for their ability to shape and affect just about every aspect of the world we live in. Yet, each week we are newly awed by publications that highlight discoveries of microbial feats and applications. This week was no different, as we were captivated by a story about a researcher who aims to cure…

List of Harmful Microbes

Bacteria are the oldest and most abundant life form on Earth. These microscopic, single-celled organisms live in all environments - including in and on the human body. A study published in May 2016 in the Proceedings of the National Academy of Sciences of the U.S.A. estimated there may be as many as 1 trillion different types of bacteria. Most bacteria are…

Microbial communities

Microbial communities

Microbial communities perform key functions for the host they associate with or the environment they reside in. Our ability to control those microbial communities is crucial for maintaining or even enhancing the well-being of their host or environment. But this potential has not been fully harvested due to the lack of a systematic method to control those complex…

Bacteria and Microbes

It began with what can only be described as an ingenious invention. It’s a fold-out sheet, with sticky tabs at the front and back, like a flattened starfish. The tabs stick to the loo seat. When in place, it forms a kind of hammock onto which the specimen is presented, ready for sampling. I slipped on the rubber gloves to prepare for the procedure. Once I had…

Defining Microbes

Microbes are organisms that are microscopic, or extremely small. Learning Objective Explain the roles of microorganisms in ecosystems and biotechnology. Key Points Microbes serve many functions in almost any ecosystem on Earth, including decomposition and nitrogen fixation. Many microbes are either pathogens or parasitic organisms, both of which can harm humans…

What is the smallest Microbe?

The smallest form of life known to science just got smaller. Four million of the newly discovered microbe - assuming the discovery, reported Friday in the journal Science, is confirmed - could fit into the period at the end of this sentence. Scientists found the microbes living in a remarkably inhospitable environment, drainage water as caustic as battery acid…

3 Main Microbes

Bacteria Often dismissed as “germs” that cause illness, bacteria help us do an amazing array of useful things, like make vitamins, break down some types of garbage, and maintain our atmosphere. more Protista Plant-like algae produce much of the oxygen we breathe; animal-like protozoa (including the famous amoeba) help maintain the balance of microbial life. more…

Microbiology Organism

Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA. Some bacteria have an extra circle of genetic material called a plasmid. The plasmid often contains genes that…

Smallest Microbe

Insects, such as mosquitoes, can spread viruses from person to person or animal to animal. When a virus attacks your body, your body remembers it. The next time it invades, your body is ready to fight it off. Some viruses, though, like the flu, can change so you can get sick more than once. Pretty sneaky trick, huh? Sometimes viruses that normally infect animals…

Difference between Microbes and Bacteria

Because bacteria and viruses cause many of the diseases we re familiar with, people often confuse these two microbes. But viruses are as different from bacteria as goldfish are from giraffes. For one thing, they differ greatly in size. The biggest viruses are only as large as the tiniest bacteria. Another difference is their structure. Bacteria are complex compared…

Disease-causing Microbes

At the turn of the last century, German physician Robert Koch identified four critical criteria for determining whether or not a particular microbe causes a disease. The ideas behind them were crucial for advancing medicine and formalizing the germ theory of disease. Over the last century, these postulates have been updated as medicine has advanced. In what may…

Characteristics of Microorganisms in Microbiology

Microorganisms are the smallest organisms on Earth. In fact, the term microorganism literally means microscopic organism. Microorganisms may be composed of prokaryotic or eukaryotic cells, and they may be single-celled or multicellular. Examples of microorganisms include algae, fungi, protozoa, bacteria and viruses. Microorganisms play many unique and complex…

What is Microbes and Diseases?

Microbial diseases are sicknesses or ailments that are caused in animals and humans by the introduction of one of four different types of microbes. Microbes are all but invisible, only seen through the use of a powerful microscope, yet are capable of causing any host they come into contact with an extensive amount of suffering if the host isn’t resilient to the…

Biological Safety Levels (BSL) are a series of protections relegated to autoclave-related activities that take place in particular biological labs. They are individual safeguards designed to protect laboratory personnel, as well as the surrounding environment and community. These levels, which are ranked from one to four, are selected based on the agents or organisms…

What does Microbes mean?

Microbes are tiny organisms such as bacteria, fungi and algae that interact with plants, animals and soil. They’re so widespread that a single gram of soil contains around 10 billion bacteria, 10 million fungi and one billion viruses. Yet we’re only just beginning to understand what microbes do, how they impact the environment, and how they can be developed as…
