Micro lab 18
Micro 204, litmus milk reactions Lab 18
| Question | Answer |
|---|---|
| Peptonization is often accompanied by the production of X. | peptides/ amino acids |
| Peptonization in milk results from the hydrolysis of X. | casein |
| A rennet curd is usually observed only under X conditions. | neutral |
| The reduction of litmus milk results when X are transferred to the molecule. | electrons |
| When gas production is so vigorous that the acid curd is blown to shreds it is called X. | stormy fermentaion |
| If the lactose in litmus milk is fermented by an organism, then the color of the litmus will be X. | red |
| When litmus turns white, it indicates that X has taken place. | reduction |
| In litmus milk, the litmus serves as both a X and X. | reducible dye molecule , pH indicator |
| X is the main carbohydrate in milk. | Lactose |
| When milk protein is hydrolyzed in litmus milk, it is called X. | peptonization |
| When a curd develops in litmus milk, how could you determine whether is was a rennet or acid curd. | the rennet curd is soft, acid curd is hard |
| A X color is the normal color of litmus milk. | Lavender |
| Color change to red, deep purple | acid, alkaline |
| De colorization | reduction |
| Hard mass | acid curd |
| Soft mass | rennet curd |
| brownish color | peptonization |
