A photo of sewage fungus found in the River Crane (London, England) Sewage fungus [1] (also known as undesirable river biofilms, URBs) is a polymicrobial biofilm (a microbial mat) that proliferates in saprobic rivers [2] and has been frequently used as a bioindicator [3] [4] of organic river pollution for the past century. [5]
Most fungal hemibiotrophs develop haustoria, whereas some produce intracellular hyphae to acquire nutrients from the host cytoplasm. [ 9 ] [ 10 ] However, in the hemibiotrophic life-style the pathogen later breaks down host cell walls through secretion of hydrolytic enzymes and feeds on the released nutrients.
The earliest terrestrial fungus fossils, or at least fungus-like fossils, have been found in South China from around 635 million years ago. The researchers who reported on these fossils suggested that these fungus-like organisms may have played a role in oxygenating Earth's atmosphere in the aftermath of the Cryogenian glaciations.
[24] [11] Bacteria can be brought to a cadaver by scavengers, air, or water. [25] Other environmental factors like temperature and soil can impact the microbes found on a cadaver. [25] The time of death can be estimated not only by the type and amount of bacteria on a cadaver, but also by the chemical compounds produced by those bacteria.
The English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').
Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types: Water body stagnation (stagnation in swamp, lake, lagoon, river, etc.) Surface and ground water stagnation; Trapped water stagnation.
The mycobiome, mycobiota, or fungal microbiome, is the fungal community in and on an organism. [1] [2] [3] The word “mycobiome” comes from the ancient Greek μύκης (mukēs), meaning "fungus" with the suffix “biome” derived from the Greek βίος (bíos), meaning “life.” The term was first coined in the 2009 paper by Gillevet et ...
A number of techniques are employed by microbiologists when culturing anaerobic organisms, for example, handling the bacteria in a glovebox filled with nitrogen or the use of other specially sealed containers, or techniques such as injection of the bacteria into a dicot plant, which is an environment with limited oxygen.
