how to recognize filamentis mold as growing on a agar plate ?
fuzzy (extensions)
large colonies
often times heavily pigmented (e.g. deep dark color)
what are some properties of filamentis mold ?
multicellular
meaning multiple cells are working together to survive & reproduce
(this usually shows as spores)
why should we not open plates with filamentis mold growing ?
we cannot open/manage plates with filamentis mold because opening the plate would expose all the spores/bacteria in large quantity all at once
(we can manage SMALL amounts because of our immune system)
are fungi eukaryotic or prokaryotic
eukaryotic meaning they have nucleus
are fungi larger or smaller than prokaryotic organisms
larger
prokaryotic organisms are smaller (bacteria and archaea)
filamentis mold species
aspergillus niger
penicilium chysagenum
what makes filamentis mold different from other organisms such as bacteria and yeast ?
they are fuzzy
what is the yeast species discussed
candida albicans
(causes vaginal yeast infections)
(part of our natural microbiota (usually low in number ))
what were the bacteria species discussed
stephylococcus arreus
escherichia coli (E. Coli)
what is CFU’s
colony forming units
how do CFU’s form
arise from ONE cell
(this makes every cell in a isolated colony genetically identical)
what process does CFU’s divide by
binary fision
