The website www.ucmp.berkeley.edu/bacteria/bacterialh.html is a resource on the UC Berkeley website that provides information on the diverse and complex group of microorganisms known as bacteria.
Bacteria are a type of prokaryote, meaning they are single-celled organisms that do not have a defined nucleus or other membrane-bound organelles. They are found in almost every environment on Earth, including in soil, water, and inside the bodies of plants and animals. Bacteria are important in many different ecological roles, including decomposition, nitrogen fixation, and the production of antibiotics.
The website www.ucmp.berkeley.edu/bacteria/bacterialh.html provides an overview of the various characteristics and behaviors of bacteria, including their size and shape, growth and reproduction, and metabolism. It also discusses the different types of bacteria, including gram-positive and gram-negative bacteria, and the various ways in which they can be classified and categorized.
One interesting aspect of bacteria is their ability to exchange genetic material through processes such as horizontal gene transfer, which allows them to rapidly adapt to new environments and evolve. This can be seen in the emergence of antibiotic-resistant bacteria, which has become a major public health concern in recent years.
In addition to providing information on the biology of bacteria, the website also discusses their practical applications in fields such as medicine, agriculture, and industry. For example, bacteria are used in the production of antibiotics, the fermentation of foods and beverages, and the cleanup of oil spills.
Overall, the website www.ucmp.berkeley.edu/bacteria/bacterialh.html is a valuable resource for learning about the diverse and important group of microorganisms known as bacteria. It provides a wealth of information on their characteristics, behaviors, and practical applications, making it a useful resource for anyone interested in learning more about these fascinating organisms.
Life History and Ecology of Bacteria

Most bacterial infections are generally in one single area of the body and are characterized by pain and some swelling. Past "Fungus of the Month" pages are also catalogued. Some plants, such as liverworts, cycads, and legumes have taken special advantage of this process by modifying their structure to house the basteria in their own tissues.

Next, place the bowl in the microwave, and let it boil for a minute, make sure it doesn't boil over you should know it's done when the solution turns clear. There are two main types of gram negative cocci, both belongs to the genus Neisseria. In general I would give things 15 minutes and 15 psi 121 centigrade to be sure. The bacteria turn nitrogen-containing molecules into nitrogen that the plant can use. One feature that has enabled them to spread so far, and last so long is their ability to go dormant for an extended period.

They may be found on the tops of mountains, the bottom of the deepest oceans, in the guts of animals, and even in the frozen rocks and ice of Antarctica. Individual bacteria can only be seen with a microscope, but they reproduce so rapidly that they often form colonies that we can see. Instead, their DNA floats in a tangle inside the cell. This resistance spreads through generations of bacteria, from passing the resistance genes from parent to it 's offspring, or by sharing genetic information between bacteria of the same generation. Viruses have no cells, nucleus, cytoplasm or cell membrane. Why do we Classify Bacteria? These produce lots of spores that are quite allergenic and some can even cause respiratory infections so take care not to inhale these.

Growing Bacteria at Home : 9 Steps
While chemoautotrophs are uncommon, photoautotrophs are common and quite diverse. This proves that the colonies developed from microbes in the inoculum rather than contaminants in the medium. Viruses are smaller than bacteria and can only be seen by an electron microscope. These bacteria are important because they help cycle nitrogen through the environment for other living things to use. What is the difference between these three types of bacteria? What do these bacteria feed on? Close to 99% of bacteria are beneficial with only a few that cause diseases.

Even the simplest virus contains only enough RNA or DNA to encode a maximum of four proteins. In conclusion, my hypothesis turned out to be correct as there were many different types of bacteria and fungi growing in my sample, and I was able to notice them in a week from when I started. How do heterotrophic bacteria get their energy? Anaerobic bacteria cannot tolerate gaseous oxygen, such as those bacteria which live in deep underwater sediments, or those which cause bacterial food poisoning. Most bacteria may be placed into one of three groups based on their response to gaseous oxygen. There are many biochemical tests that can separate the different groups and the different species, enabling physicians to make an accurate diagnosis of bacterial infections. The most complex virus; on the other hand, can encode anywhere to 100 to 200 proteins.

Bacteria and Viruses Webquest
Retrieved October 30, 2013, from. I learned how to test the effectivity of different antibacterial products and I learned how to differentiate between a fungus and bacteria by eye, and most importantly I learned about the importance of bacteria in our daily lives and how sometimes bacteria can save us. Take your sample over the sink and start pouring bleach over it making sure to not let any of the bleach touch your skin, this should kill the bacteria left over, after that place it in a sealed plastic bag and then dispose of it in the trash. This would allow you to assess the quality of your sterilization and aseptic technique, The hypothesis that both sterilization and aseptic technique were both perfect would suggest that no microbial colonies should be found on the control plates while colonies develop on the inoculated plates. When studying for this course, always use your manual as a guide: Looking ahead to Lab 5 on the Kingdom Fungi, you should know about the "Fungus of the Month" page sponsored by Tom Volk at the University of Wisconsin campus in La Crosse. Bacteria put the tang in yogurt and the sour in sourdough bread; bacteria help to break down dead organic matter; bacteria make up the base of the food web in many environments.

The complete communicable virus particle, a virion, is composed of nucleic acid and an outer shell of protein called a capsid and on occasion, a virus may have a membrane envelope. Streptococcus appears on this server courtesy of the Berkeley Free Clinic. When most people think of bacteria, they think of disease-causing organisms, like the Streptococcus bacteria growing in culture in this picture, which were isolated from a man with strep throat. For example, some bacteria live in the roots of legumes, such as pea plants Figure below. Two of the seven types make up the majority of all bacteria. UCSB Science Line UCSB Science Line How did bacteria develop on Earth? Bacteria are of such immense importance because of their extreme flexibility, capacity for rapid growth and reproduction, and great age - the oldest fossils known, nearly 3.

Classification of bacteria
Agar is a gelatinous medium that provides nutrients and a stable, controlled environment for bacteria growth. An example of one of these chemicals broken down by bacteria is nitrogen-containing ammonia. Photograph of Leptospira provided by William A. I would have included a Petri dish of medium that was not inoculated at the start but incubated along side your experimental plates. Many groups just have their names listed.

5.3: Bacteria Nutrition
Looking at your plates there are a lot of sporulating fungi evident. The common cold and flu are examples of a virus at work. Now that you have all the materials ready its time to start the experiment. Bacteria produce nearly half of the oxygen found in the atmosphere. They can be classified as follows: Cocci The gram positive cocci include the well known species Streptococcus and Staphylococcus. I used these skills nearly the entire time I was working on the project.

Introduction to the Bacteria
While chemoautotrophs are uncommon, photoautotrophs are common and quite diverse. In this experiment, I learned many things. Gram negative bacilli are a large and varied group that are divided into different categories. They may have a natural immunity, but they may also have a gene mutation, or acquire resistance from another bacterium. It occurs when the harmful bacteria enter our body through contaminated, non pasteurized or expired foods; cuts or sores on our skin; and even through open passages such as eyes, ears, teeth or genitals. He has basically put his entire undergraduate course on line. Viruses consist of tiny particles of nucleic acid enclosed by a coat of protein.
