Can a human die from mold?
Aspergillus sppAspergillus is the most common genus of fungi in our environment with more than 160 different species of mold. Sixteen of these species have been documented as causing human disease. Aspergillosis is now the 2nd most common fungal infection requiring hospitalization in the United States. Exposure to aspergillus can often cause skin rashes and hair loss. Many people seek relief by taking 5,000 mcg. of biotin per day with 3,500 mgs. of MSM. Beware, many vitamins and supplements are made with the aspergillus fermentation process or other types of fungi that the vitamin manufacturers fail to reveal. For a healthy source of vitamins with no fungi, please view the related link; the world's first nutricutical website for providing relief from fungal exposure. The site is in its initial stages at the moment, but by February 1, it will be an entire source for healthier eating and nutritional supplements related to fungal disease. Please register on the site if you would like an update when the Mold-Help Solutions Source is ready to assist.Aspergillus fumigatus. The most encountered species causing infection. It is seen abundantly in decomposing organic material, such as self-heating compost piles, since it readily grows at temperatures up to 55 C. People who handle contaminated material often develop hypersensitivity to the spores of Aspergillus and may suffer severe allergic reactions upon exposure.Aspergillus flavus. The 2nd most encountered fungi in cases of Aspergillus infection. It is also known to produce the mycotoxin aflatoxin, one of the most potent carcinogens known to man. In the 1960s, 100,000 turkey poults in Great Britain died from ingesting contaminated feed. Most countries have established levels for aflatoxin in food. However, the risks associated with airborne exposure are not adequately studied and no exposure standards exist.Aspergillus niger. The 3rd most common Aspergillus fungi associated with disease and the most common of any Aspergillus species in nature due to it's ability to grow on a wide variety of substrates. This species may cause a "fungal ball", which is a condition where the fungus actively proliferates in the human lung, forming a ball. It does so without invading the lung tissue. It has also been linked to hearing problems including tinnitus and hearing loss.Aspergillus Versicolor. The most common species of Aspergillus. Among skin problems and hair loss, this fungus has been linked to severe abdominal pain, acid reflux, and vomiting.
Role of rhizosphere microflora in environment microbiology?
The term "Rhizosphere" was introduced in 1904 by the German scientist L. Hiltner to denote the region of soil, which is under the influence of plant roots.Rhizosphere is defined as the region of the soil immediately surrounding the roots of a plant together with the root surfaces.Plant roots receive between 30-60% of the net photosynthesized carbon. Of this, an estimated 40-90% enters the soil as a wide variety of materials including alcohols, ethylene, sugars, amino acids and organic acids, vitamins, nucleotides, polysaccharides, and enzymes. These materials create a unique environment for soil microorganisms, called the rhizosphere. The plant root surface, termed rhizoplane, also provides a unique environment for microorganisms, as these gaseous, soluble, and particulate materials move from the plant plant to soil.The rhizosphere effect is beneficial to the plants in two ways, firstly it helps in providing nutrients to the plants and secondly, it helps the plants in combating root diseases;Here, soil environment may be aerobic or anaerobic. And here Bacteria predominate rather than fungi.Mainly soil bacteria present:Achromobacter, Pseudomonas, Bacillus, Clostridium etc.Fungi such as: Aspergillus flavus, A. niger, Cladosporium herburum, Fusarium oxysporum, and F. solani.Rhizosphere microorganisms are directly associate with root system, i.e, no vector is needed.- Tathagata Bhattacharjee.student of M.Sc -1st year,B.R.S.N College,West Bengal State University.
What organisms are involved in the composting process?
E. coli and other chloroforms may be found in compost if animal feces are added in. In enclosed spaces the compost can heat up though, which would kill off most of the chloroforms. From a paper on the microbiology of composting pig waste: A total of 274 bacterial and fungal isolates were recovered from the composting waste and majority (60.58%) were isolated from the open heap. Bacillus subtilis, Pseudomonas aeruginosa and Aspergillus flavus were the predominant isolates recovered (9.49% each), and were the only isolates recovered throughout the period of composting irrespective of the composting technique. Staphylococcus aureus and Salmonella typhimurium were the least isolated (1.09% each).
Which type fungi produces the carcinogenic aflatoxin?
Aspergillus species, most abundantly Aspergillus flavus
Are metulae present in aspergillus flavus?

What is aflotoxin?
A food poison, caused by the toxin produced from the yellow mold, aspergillus flavus.
What is the difference between verotoxin and ablotoxin?
The difference between verotoxin and ablotoxin is that verotoxin is a toxin generated by some strains of Escherichia coli while aflatoxin are mycotoxins generated by Aspergillus flavus and Aspergillus parasiticus,some species of fungi.
What peanut is unsafe?
Any peanut which exhibits the black fungus known as Aspergillus flavus or Aspergillus parasiticius. The two fungi produce aflatoxins (mycotoxins) which are among the most carcinogenic substances known.Health inspectors will condemn a boatload of peanuts if black mold is discovered.

Three different types of fungi and what they do?
BRACKET FUNGI:-Bracket fungi are commonly found growing on trees or fallen logs in damp woodlands. They can severely damage cut lumber and stands of timber.PENICILLIUM:-Common on foodstuffs, leather, and fabrics, they are economically important in producing antibiotics organic acids, and cheeses such as English Stilton, Italian Gorgonzola, and French Roquefort.ASPERGILLUS:-Aspergillus niger causes black mold on some foods; Aspergillus niger, Aspergillus flavus, and Aspergillus fumigatus cause aspergillosis in humans. Aspergillus oryzae is used to ferment sake, and Aspergillus wentii to process soybeans.
