Will UV light kill mold the way it does bacteria?

Definitely yes, most laminar flow hoods are equipped with fixtures for UV lights and it is a common practice in labratories to use these lights for sterilization of the hood surfaces and tools.

I work for a mold laboratory. There isn't a difference between mold and mildew. In fact they are both technically a fungus. Just like the mushrooms in your yard are a fungus. \n\nTo be honest though if you are just looking to kill mold in your house it is cheaper and just as effective to use one part bleach to 9 parts water and put it in a spray bottle. \n\nYou don't need to have any fancy cleaners unless you have the "black mold" and that actually isn't found that often. \n\nPlease feel free to email me if you have any futher questions.

It depends on what preservatives were used, how hot it is, how humid it is, how you are storing the bread, whether it has been sliced and a gretamany other factors. In the tropics it's quite possible to see visible mold develop on fresh bread overnight.\n\nOf course visible mold is not the same as mold. Mold will start groing on bread almost as soon as the first spore hits it after it has cooled. In the strictly biological sense mold will be growing on most sliced bread within a couple of hours.

it's totally depends on the type of the bacteria!\n1)sterilization:fungi is so sentitive to this condition.but if the bacteria is the kind that produce endospore then this method is not useful\n2)pasteurization:kills all the bacterias except the one couses Query\n3)filterization:useful for bacterias except Mycoplasma\n4)Rays like UV X and Gamma\n5)chemical Gases which are mutagenes like rays\n6)chemical liquids

Live bacteria seems unlikely. Bacterial spores, no problems.\n\nYou would have more luck trying to isolate fungi.

It depends on what sort of microorganisms you wish to grow.  If you'd like protists, just go to any local pond, take a sample of the water and you'll have an instant microcosm.  If you're specifically interested in bacteria or fungi- all you really need to do is leave out some moist, fatty nutrient-rich substance (like milk) and soon enough mold spores (mold is a fungus, by the way) in the air will settle and grow, as will bacteria.  (It's important to note that there is no such thing as "spontaneous generation" - These microorganisms will grow from air-borne spores or spores that are already present in the container / within the substance you grow them.  They don't just simply generate from nothing.)

There's not UV filtering, no ozone layer to protect it.  It will be burned by UV radiation.

thats not mold,thats flour....they dust it with flour b4 they bake it...(on some breads)...most bread mold will turn green, from the yeast.

bleach if the cloths are white. but i guess if its like mold you could leave it out to dry in the sun.

I suggest hydrogen peroxide 'bleach' because it is much less toxic than regular bleach, but it still destroys many pathogens.\n \n Also, 70% Isopropyl alcohol is a good disinfectant.

Depends on the bacteria.  Light can damage cells.  UV light is used to kill bacteria, and a single cell has very little defense to the sun's light, oppose to multicellular creatures.  On the otherhand there is more food in the light.  Especially for cyanobacter, who needs light to survive.  My guess is that there is a lot more bacteria in the dark, because their are alot more dark places.

It can't face the UV rays of sunlight. As well as the infrared rays from the sunlight affect it.\n\nBulbs won't affect it though!

You have to be more specific.  Microorganisms grow in pretty much every condition on Earth, including hot and sulfurous ocean water by volcanic vents, in ice at the poles, in badly-preserved jars (botulism--anaerobic), inside the body, in ponds, in caves, in the dark, in the sunlight...it all depends on the specific type of microorganism.\n\nFor instance, sugar tends to kill bacteria, but mold loves sugar.  So a jar of jelly left in a fridge for a long time (cold, wet, sugary environment for the microorganisms) might not have bacteria, but it could have fuzzy mold on it.  It all depends.  \n\nBut from a food safety standpoint, you want food kept either below 40 degrees fahrenheit, or above 140 degrees, and keep it wrapped up and covered to avoid stuff dropping in it.  In general, microorganisms like: warm (not hot or cold), dark, moist, and somewhat neutral pH.  That'll grow mold, mildew, fungus, and many types of bacteria.  They usually don't like clean surfaces and they tend to die in chlorine bleach.

Yes, you can cause mutation by reduction/increasing of exposure time or increase/decrease distance of bacteria culture dish from UV source or by use of some filters to reduce UV wave power if it has more power.

Growing penicillium molds\nStep 1: Take a piece of bread and gently wipe it against the kitchen floor or against a windowsill. Microbes will stick to the bread even though they are invisible to the naked eye.\n\nStep 2: Sprinkle some water on the bread; an eyedropper or laundry sprinkler will work well. Microbes require moisture for growth.\n\nStep 3: Place the bread in a jar of some sort and cover the jar with a lid. Plastic wrap, aluminum foil or anything similar can act as a substitute for a lid if it is missing. There is no need to puncture “air-holes” in the lid as the microbes will have enough oxygen for growth. Place the jar in a cupboard, or somewhere dark and warm.\n\nStep 4: After a few days you can look at the bread. If you see bluish-green mold growing, it is probably Penicillium. If you do not see any mold colonies put the jar back and wait a few more days – some bread contains chemicals such as calcium propionate to slow the growth of mold.\n\nStep 5: Pass a sharp knife through the bluish-green mold on the bread, and, using the same knife, make several deep cuts in the skin of an orange.\n\nStep 6: Wash and dry the jar previously containing the moldy bread with plain water. Place a wet piece of cotton or tissue paper in the newly-cleaned jar along with the orange. Cover the jar and store in a dark, warm place.\n\nStep 7: Examine the orange each day for any mold which may grow along the cuts. After a week or so you may notice tiny drops of liquid forming along the cuts. The liquid will be yellow or gold in color. Penicillin is manufactured from these chemicals.
