Yeasts have been used since ancient times to leaven bread and to ferment beer and wine. [2] More recently, fungi have been used for a wide variety of industrial fermentations, whether working directly for their effects on materials such as processing paper pulp or bioremediating industrial waste, or serving as the source of enzymes for many purposes, such as fading and softening denim for ...
Sewage fungus is a type of microbial mat, the specific composition of which is affected by the available nutrients (especially organic carbon sources) and the environmental drivers of each unique occurrence. However, several key taxa are reported as highly frequent and dominant within sewage fungus.
Environmental chemists draw on a range of concepts from chemistry and various environmental sciences to assist in their study of what is happening to a chemical species in the environment. Important general concepts from chemistry include understanding chemical reactions and equations , solutions , units , sampling , and analytical techniques .
Researchers studied the effect white-rot fungi could have on absorbing heavy metal ions via alginic acid, a linear polysaccharide composed of 1,4-linked beta-D-mannuronic and alpha-L-guluronic acid. The findings from the study indicated that Fungalia trogii was capable of biosorption of Hg 2+ , Cd 2+ , and Zn 2+ in low pH environments. [ 41 ]
Mycotoxicology is the branch of mycology that focuses on analyzing and studying the toxins produced by fungi, known as mycotoxins. [1] In the food industry it is important to adopt measures that keep mycotoxin levels as low as practicable, especially those that are heat-stable.
Where conditions are right, fungi proliferate into colonies and mycotoxin levels become high. The reason for the production of mycotoxins is not yet known; they are not necessary for the growth or the development of the fungi. [9] Because mycotoxins weaken the receiving host, they may improve the environment for further fungal proliferation.
Monarch butterfly caterpillar on milkweed plant.. Plant, microbe, and insect chemical ecology focuses on the role of chemical cues and signals in mediating interactions with their abiotic (e.g. ability of some bacterium to reduce metals in the surrounding environment) and biotic environment (e.g. microorganisms, phytophagous insects, and pollinators).
They contain a very small amount of water (5–10%) and can survive in a dry environment for several years without losing the ability to grow. In most cases, the sclerotium consists exclusively of fungal hyphae, whereas some may consist partly of fungal hyphae plexus and partly in between tissues of the substrate (ergot, Sclerotinia).
