4. Would one's streaking technique affect a bacteria's cultural characteristics and if
so, why?
Yes, because streaking thins out the
inoculum by spreading it through the agar which
seperates the bacteria into isolated colonies
5. Would one's aseptic technique affect the cultural characteristics and if so, why?
Yes, because you can contaminate it by
poor aseptic technique giving you a wrong
number of bacteria.
