Are Lichens fungi?
The plant-like appearance of lichens hides their true identity. A lichen is not a single organism, but the result of a partnership (mutualistic symbiosis) between a fungus and an alga or cyanobacteria. Some lichens are formed of three or more partners. The body of a lichen consists of fungal filaments (hyphae) surrounding cells of green algae and/or blue-green cyanobacteria. The basis of the mutua

Designing indicators for ecological effects of bioremediation
Pentachlorophenol-contaminated soil was amended with a strain of Pseudomonas capable of biodegradation of the pollutant. After bioremediation was complete, soil was tested for indicators of ecological condition. Several direct-toxicity measures (plant seed germination and root elongation, earthworm survival) showed the bioremediated soil to be indistinguishable from clean reference soil.

Explain how Penicilin helps fight bacteria
Antibiotics are chemicals, effective at very low concentrations, created as part of the life process of one organism, which can kill or stop the growth of a disease-causing microbe--a germ. In 1929, Alexander Fleming, a doctor and researcher at St. Mary's Hospital in London, England, published a paper on a chemical he called "penicillin", which he had isolated from from a mold, Penicillium notatu

How do different temperatures affect the growth of fungi?
My hypothesis is that fungi will thrive in warmer temperatures.

How to grow mould in a moist chamber
The simplest method of growing molds is to put a substrate like bread in a moist chamber. The substrate provides nutrients, and the chamber maintains the high humidity that favors the growth of fungi.

How to grow your own yeast fungus
The yeasts are one very important group of fungi. The common yeast used in baking bread grows very fast. You can complete an experiment in two days! The basic idea in this method is to measure the amount of carbon dioxide (CO2) released during the growth of yeast.

Safe storage of bread
This science fair project was conducted to ascertain what conditions will help prevent bread from becoming moldy. The bread was kept in different environments to observe the time taken for mold to appear.

The Effect of Environmental Factors on Wood Decay
This science fair project was conducted to find out how the environment affects the decaying process in wood. The following tests were carried out by first immersing the wood in either rainwater, acid water (which simulates acid rain), sea water or soil

The Effect of Various Treatments on the Mold Growth of Red D'Anjou Pears
The purpose of this experiment was to determine the best way to reduce blue mold (Penicillium), and gray mold (Botrytis cinerea) on red D’Anjou pears, in open air. The information gained from this experiment would benefit most fruit growers, especially pear growers, by reducing their reliance on fungicides.

The fungus among us: it's a bird, it's a plane, it's a mold spore!
Fungi often go unseen because of their small size, but they are important to us in many ways. Some fungi are beneficial to us and are used to make medicine, such as penicillin. Yeast, a kind of fungi, causes bread to rise in baking. Other types of fungi are not so beneficial, and can cause diseases such as athlete's foot and other infections. Fungi need particular conditions for growth. In this s
