[Oww-Feedback] mistakes in the entry "M9 medium/minimal" (from Markus)

[Austin Che]

    Thanks for your comment. However, your numbers do not appear
    to agree with other sources.

    If you have a source for your numbers or would like to discuss it,
    I would suggest getting an account on openwetware and discussing
    on the appropriate talk page.

>>1x M9 salts 
>>2mM MgSO4 
>>0.1mM CaCl2 
>>0.4% carbon source (e.g. glycerol, glucose, etc.) 
>>In sterile H2O

> The concentration of 0.1mM CaC12 is to high, it sould be 0.1µM. The same with MgSO4 --> 2µM not 2mM.
> And maybe it would be good to tell the people that they should add low concentrated CaCl12 (e.g. 10ml of 10µM to 1l) to avoid precipitation.
