Can one make petri dish material from pasta?

After making some pasta in very little water, I noticed that what water remained after I poured it out had congealed to a jello like blob. Is this because of the starch? And if so, would this work to grow bacterial cultures?

A lot of bacteria will produce enzymes that dissolve the starch. That's why they use agar; fewer organisms have evolved to eat boiled seaweed.
