This is a multi-part message in MIME format. ------=_NextPart_000_0016_01C08730.F1A0C880 Content-Type: text/plain; charset="windows-1255" Content-Transfer-Encoding: quoted-printable Hi Gavin! =20 I answered your question and would like to correct and expand my answer. The term auxotrophic relates to prokaryotic organisms that cannot = produce essential compounds for their "living" (such as germs that = cannot produce the amino acid argenin) in comparison to the wild type of = that particular type of germ. The term prototrophic means the opposite of auxotrophic and relates to = prokaryotic organisms that can produce essential compounds for their = "living", another words, the term autotrophic refers to the wild type of = a prokaryotic organism. The term autotrophic refers to a completely different part of = microbiology. Prokaryotic organisms are classified into four main = categories. The first category is divided to two parts that are = differentiated by ability of the prokaryotic organisms use different = substances as a source of energy. The first group is called phototrophs = that use sunlight as a source of energy and the second group is called = chemotrophs use organic compounds as the source of energy. The second = category is divided to two parts that are differentiated by ability of = the prokaryotic organisms use different substances as a source of = carbon. The first group is called autottrophs that use carbon di-oxide = as a source of carbon and the second group is called hetrotrophs that = use organic compounds as the source of carbon. I will be happy to answer any of your other questions in: biology, = microbiology, chemistry, biochemistry etc. at my email: = alonnardi@yahoo.com > "Gavin" <gavin@zonvark.wustl.edu> wrote in message > news:39EF2F13.83985F53@zonvark.wustl.edu... >Hi, > > Just a quick question: What does "auxotrophic" mean? > I suspect it is not the same as "autotrophic". > > Gavin ------=_NextPart_000_0016_01C08730.F1A0C880 Content-Type: text/html; charset="windows-1255" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Dwindows-1255"> <META content=3D"MSHTML 5.50.4207.2601" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>Hi Gavin!<BR> </FONT></DIV> <DIV><FONT face=3DArial size=3D2>I answered your question and would = like to=20 correct and expand my answer.</FONT></DIV> <DIV><BR><FONT face=3DArial size=3D2>The term <STRONG><FONT=20 color=3D#0000ff>auxotrophic</FONT></STRONG> relates to prokaryotic = organisms that=20 cannot produce essential compounds for their "living" (such as = germs that=20 cannot produce the amino acid argenin) in comparison to the wild = type of=20 that particular type of germ.<BR><BR>The term <STRONG><FONT=20 color=3D#ff0000>prototrophic</FONT></STRONG> means the opposite of = auxotrophic and=20 relates to prokaryotic organisms that can produce essential compounds = for their=20 "living", another words, the term autotrophic refers to the wild type of = a=20 prokaryotic organism.<BR></FONT></DIV> <DIV><FONT face=3DArial size=3D2>The term autotrophic refers to a = completely=20 different part of microbiology.

That implies expertise, coupled with some ability to know what one knows and what one does not. And now we see that even an attempt to correct a reply is incorrect.
