Agar plate authors and history
= From Wikipedia:Talk:Agar plate = The agar solution doesn't necessarily need to be boiled to dissolve (as a first step); as long as it is thoroughly mixed, the autoclave's heat and boiling of the water during sterilization will cause it to go into solution. Tygar 07:13, Feb 12, 2005 (UTC)

Suggested move to wikibooks
I disagree that this article should be moved to wikibooks as per the recently added tag. It may well be that the article can be improved and made more encyclopaedic and that some of the "how to" might belong elsewhere, but as a frequent user of wikipedia, I was searching for this infomation here and expected to find it on wikipedia--User:AYArktos | Talk 01:42, 20 September 2005 (UTC)

Question about incubation times
How long are the plates usually incubated for? I assume it depends on the experiment. --User:AYArktos | Talk 01:50, 20 September 2005 (UTC)
 * In my limited experience - a few days. Theresa Knott (a tenth stroke) 02:13, 20 September 2005 (UTC)


 * From distant memory, when looking for most human pathogens, plates are incubated for two days in total, although many are looked at after one day, before being reincubated.


 * For slower growing pathogens (e.g Campylobacter, Bordetella), plates are sometimes incubated for longer. But for commoner Staphs, Streps, candida, respiratory bugs, gram negative bacilli, etc., two days is sufficient. Every lab will have their own protocols however.

needs to be better
it doesn't have enough information or is understandble for a year 8 student myself.
