Inhibit TRANSLATION via 30s subunit, blocking A site.
Not chemically pure, use complex sources of nutrients. (Grows most chemo and photoautotrophs)
Gives competitive edge to desired microbe so it becomes dominant species. SPECIFICALLY ENCOURAGING.
Inhibits synthesis of MYCOLIC ACID (only found in Tb Mycobacterium)
Inhibits PROTEIN SYNTHESIS via 50s subunit, blocking peptide bond formation
Encourages growth of some microbes and inhibition of others. SPECIFICALLY INHIBITING.
Inhibits TRANSCRIPTION via binding of RNA polymerase
Reassortment of gene segments (causing changes in H or N proteins) (where two different strains of flu viruses infect the same host cell and are incorporated into a single new capsid)
Has general nutrient supplements. GENERALLY ENCOURAGING for most microbes.
Chemical substances produced by microbes that kill or inhibit the growth of other microbes.
Lipopolysaccharide of O-specific polysaccharide, core polysaccharides and Lipid A
Nucleic acid, protein coat and may have lipid envelope
