Fungi straddle the realms of microbiology and macrobiology.
Fungi can be found in rising bread, moldy bread, and old food in the refrigerator, and on forest floors. Most decompose non-living things, but some damage crops and plants. A few cause problems in people, such as Candida, which causes yeast infections.... Read More
As the “humongous fungus” shows, fungi can grow to enormous mass if unimpeded.
Hyphae grow by adding cells at the tip. Hyphae are very tiny, measuring only a few microns in diameter in some cases. But they can also be incredibly strong, punching through not only the soft membranes of animal ... Read More
There are some nasty fungi that cause diseases in plants, animals and people. One of the most famous is Phytophthora infestans (fie-tof-thor-uh in-fes-tuhns), which caused the Great Potato Famine in Ireland in the mid-1800s that resulted in a million deaths. See the Read More
Viruses may be referred to often as the smallest infectious things. But there are some smaller contenders. Some of the agents of plant disease lack even a viral coat and are merely small strings of plain, or "naked," RNA. These particles are called viroids. They are believed ... Read More
Fungi absorb nutrients from living or dead organic matter (plant or animal stuff) that they grow on. They absorb simple, easily dissolved nutrients, such as sugars, through their cell walls. They give off special digestive enzymes to break down complex nutrient... Read More
Major development projects are taking place in oceans across the globe all the time, enterprises that will provide shelter and food for a vast number of fish, mussels, urchins, and other marine life.
Microbes require nutrients to grow. These are supplied by either solid or liquid culture media. The standard solid medium is nutrient agar, a gelatinous substance derived from seaweed. The basic liquid medium is nutrient broth, typically a mix of water, meat extract peptone, and sodium chlori... Read More
When microbiologists want to identify microbes in a sample or study microbes in-depth, they often try to culture, or grow, the microbial cells in their labs. The scientists can then manipulate the cells or their environments to see what effects these changes have on the organisms.
There are a lot of young people who haven't thought much about a career as a scientist. Some of them may think they're not smart enough. Some think science is boring. In other words, people believe a lot of myths. Here are some of the most common ones.
