Can we bacteria (in yogurt) with this microscope?

I haven't purchased this yet, but 1000x should be far more than enough for bacteria. You would have to prepare the slide, by heat it for a few seconds over a gas flame or electric stove eye on high to denature the protein. This is solidifying the bacteria, in the same way an egg solidifies when fried. It will then need a drop of stain on it for a few seconds, followed by rinsing with water. It should then be ready for a cover glass and viewing. Stain is essential for bringing out the detail in cells and bacteria.

This scope seems strong enough for protists, but bacteria are much smaller. I haven't tried, but I think you will need something with greater power to see bacteria.

As far as I know you can. I've been doing a lot of research on yogurt making and that was never mentioned as counter-indicated.

I don't know what to tell you. It works just like that for me. How thick is your yogurt when you put it in?

I use a packaged yogurt starter which has a blend of specific bacteria and are (presumably) alive when rehydrated. Even so, eventually you need a new starter when reusing your own yogurt as the population of bacteria change in both type and proportions. This leads me to store bought yogurt as a starter. Since there are so many yogurts (Supermarket vs. places like Whole Foods and Sprouts), you don't know exactly what is in that yogurt or how it was treated (shipping and storage), I think even with plain yogurt the results could be hit or miss. If you want to try a fruit yogurt I would suggest one where the fruit is on the bottom (Dannon?) rather than a homogenized one (Yoplait) and making sure that the label says "Contains Live Cultures". Organic may be better than non-organic but in the end, you may have to experiment.

Apparently not. For the first few uses, cleaning was a cinch, with a quick rinse being all that was needed. Without any change in my recipe for yogurt, it has become almost impossible to clean thr screens and they are ebginning to tear. I find that some vinegar helps with some of the cleaning.

We haven't tried it yet, but you in general you can make yogurt using starter from store-bought yogurt that has live bacteria. So it should work with this machine.

Yes. I can easily see organisms that are much smaller like bacteria and yeast. Observing soil organisms will be easy :)

yes if you have it on the yogurt setting. it may be a few degrees higher than 110 though

Germs are microscopic, but it might reveal colonies of bacteria. I guess many organic fluids, such as those our cats secretly secret around the house, are entirely evident with this light, especially when you also use the tinted googles.

That I cannot answer for sure, but I don't see why not. The success to making yogurt is temperature, not what it's made in.

yes--- however you can buy the little dipper/sauce cups from lunchbots and place one of those filled with yogurt inside! or something similar....

You can use any milk so I guess it would be okay if it is raw. then yogurt actually "cooks" for'10 hours so I don't guess it would be raw anymore???

Yes, you can. The recipe book suggests freezing regular yogurt and using it in the machine.

I use it for making yogurt. It's very accurate when testing the temperature of warm milk. It should be just fine for bread.

It is a really low temperature for an extended period of time, to create the fermenting of the yogurt. I'm not sure it would kill bacteria like you would need it to, for a baby's food.

I would think that would be the ideal way to use the culture. I could only find pasteurized milk that wasn't homogenized. I would have rather used the raw milk.

You can certainly make yogurt using the Square Rutes Dehydrator! In fact, the square/cube-shape of the unit allows for many sized jars to be used to make yogurt.
