Growing mushrooms indoors may seem like a mysterious practice, but it is rather simple when done with the right materials. Mushrooms require a substrate to grow upon, such as rice, wood or spent barley. The substrate makes a warm, moist, decaying medium
"It had morphological shapes and structures to it, which suggested that this organism had undergone a really profound change. That allowed it not only to be resistant to this drug, which causes lysis, but also to move as a population of bacteria across the agar surface in a petri dish," ...
bacteria of the same species may need several days to double in especially harsh environments. Most pathogens grow rapidly, likeE. coli, but there are exceptions. For example,Mycobacterium tuberculosis, the causative agent of tuberculosis, has a generation time of between 15 and 20 hours. On the...
