Orange Mold Has Been Identified And It Turns Out He/She Is Famous And I Use the Term He/She Very Intentionally

Nearest neighbor joining tree from alignments of 18S rDNA intergenic sequence (ITS) data for a single orange mold isolate obtained via generous donation form a local testing lab whose identity must remain a closely guarded secret. This is to protect both the laboratory and all the members of our little Microbe of the Month club from the bad people who want to shut down our operation. They do not understand that we are providing a valuable service to the community and having fun while we learn just like they always want kids to do but then they make those terrible games and toys that are the exact opposite of fun and wonder why nobody ever buys them. Also, they are no fun having captain buzzkills.

“Neurospora is highly valued for research purposes. First, it is easy to grow. Second, its simple life cycle makes it easy to study genetics and map genes. Because its characteristics make it ideal for scientific research, Neurospora is considered a model organism.”

Excuse me sir, what did you just say? can you please repeat that because I thought I heard you say something about highly valued and model organism? Now the easy to grow part we are on the same page with, but the rest, I have to say I am stunned. Also, your grammar was terrible but since I copied you directly from a web page I cannot be blamed.

Neurospora species are apparently incapable of causing disease in animals.

Certain innate characteristics make it unlikely that Neurospora will have adverse effects on animals. Unlike yeasts, Neurospora species are obligate aerobes, unable to grow in the gut or bladder, in tissues, or systemically. Aside from its use in the laboratory, Neurospora has long been known to occur in close association with humans in contaminated bakeries, lumber yards, and plywood factories; on steamed logs………Despite the many opportunities for human exposure to the powdery airborne conidia, no evidence has been obtained that Neurospora is the causal agent of any disease or infection.

Contamination by Neurospora is readily controlled.

(say what what? You sir are a captial L i a r liar, pants on out of control, massive inferno, fire). Because of its high growth rate (3 to 5 mm/h) and the ease with which the powdery conidia become airborne, Neurospora has gained a reputation in some quarters as a laboratory contaminant. (well deserved thank you very much) This reputation is largely undeserved. (hey did you read my mind or something, I hadn’t even read the next sentence yet when I wrote, well deserved thank you very much, and then wouldn’t you know it seems as if you were replying directly to me, crazy.) Cross-contamination or overgrowth of slowly growing cultures by Neurospora is not a problem in any well-ordered research laboratory.(Excuse me sir are you implying that I do not work in a well ordered laboratory, I will have you know, you are correct, but we are getting better) Good laboratory practice includes avoidance of drafts, attention to cleanliness, autoclaving of discarded cultures and contaminated glassware before dishes are washed, and care not to incubate cultures in closed containers in which humidity approaches 100%. Thousands of Neurospora strains are maintained in pure culture, without problems of contamination, in leading research laboratories and at the Fungal Genetics Stock Center, University of Kansas Medical Center, Kansas City. (well good for leading researhch laboratories and the Fungal Genetics Stock Center, aren’t they special, show-offs)
