&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;=R5=&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Preparation==&lt;br /&gt;
Make up the following solution:&lt;br /&gt;
*103 g Sucrose&lt;br /&gt;
*0.25 g K&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;SO&amp;lt;sub&amp;gt;4&amp;lt;/sub&amp;gt;&lt;br /&gt;
*10.12 g MgCl&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;.6H&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;O&lt;br /&gt;
*10 g Glucose&lt;br /&gt;
*0.1 g Difco Casaminoacids&lt;br /&gt;
*2 ml [[trace elements solution]]&lt;br /&gt;
*5 g Difco yeast extract&lt;br /&gt;
*5.73 g TES buffer&lt;br /&gt;
*To 1000 ml dH&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;O&lt;br /&gt;
&lt;br /&gt;
Pour 100 ml of the solution into 250 ml Erlenmeyer flasks each containing 2.2 g Difco Bacto agar.&lt;br /&gt;
Sterilise by autoclaving.&lt;br /&gt;
At the time of use, remelt the medium and add to each flask the following autoclaved solutions in the order listed:&lt;br /&gt;
*1 ml KH&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;PO&amp;lt;sub&amp;gt;4&amp;lt;/sub&amp;gt; (0.5%)&lt;br /&gt;
*0.4 ml CaCl&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;.2H&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;O (5M, 3.68%)&lt;br /&gt;
*1.5 ml L-proline (20%)&lt;br /&gt;
*0.7 ml NaOH (1N) (unsterilised is okay)&lt;br /&gt;
*0.75 ml Required growth factors for auxotrophs&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Uses==&lt;br /&gt;
*See [[R2YE]] - just an alternate way of making but folklore suggests less reproducible results on R5.&lt;br /&gt;
&lt;br /&gt;

==Notes==&lt;br /&gt;
&amp;#039;&amp;#039;[[Streptomyces clavuligerus]]&amp;#039;&amp;#039; does not utilise glucose and it must be substituted by glycerol.&lt;br /&gt;
