I think it is Aspergillus niger: On the second place I'd suggest Black Mold disease caused by Alternaria species.

Transcytosis is a process by which large macromolecules are transported across a cell, such as those in the intestinal epithelium. It is used by many toxins and even whole organisms to enter the body. Botulinum toxin also apparently uses this mechanism. I'm not sure how detailed of an answer you want, but the linked to-review is pretty in-depth.

If by "simplest" you mean smallest genome, then according to Brock's Biology of Microrganisms (13th ed, p 319) the smallest autotroph is Aquifex aeolicus, a chemolithotroph bacterium. It's genome is 1.5M bases, about 1/3 of that of E.Coli, and was sequenced in 1998 (https://www.ncbi.nlm.nih.gov/pubmed/9537320). The genome is densely packed though and still ...

To build on busukxuan's answer, there are a lot of single-celled organism responses that kind of resemble memory: Slime mold uses an externalized spatial 'memory' to navigate in complex environments - essentially, a slime mold leaves behind a trail, which it then avoids, allowing it to avoid where it has traveled in the past. If you apply a periodic ...

Short answer: Antibiotic treatment is important because the body can't always keep up with the infection even if it has launched a response. Background: First, let's look at what the antibody reaction method is actually doing.

Our Unique Microbial Identity (Gilbert 2015) suggests that the gut microbiome is shaped and stablized during infancy and tends to restore equilibrium if it is disturbed later in life. Antibiotics temporarily change the composition of the gut microbiome (by suppressing the growth of certain groups of bacteria more than others), but it tends to drift back to ...

It would also depend on the pore densities and pressure resistance. Silica is used for gel filtration chromatography to separate proteins. This can be achieved when proteins do not have affinity to silica, and most of proteins could be analyzed with silica gel. Silica and grass are similar materials. However, glass and silica have negative charges on the ...
