Bioluminescent Bacterial Lightbulb / Water Pollution Tester
Microbial Fuel Cell Of Science!!!
How long is the barrier good for? Does the salt eventually get dispersed into the water?
waow cool! produce electricity and the fish can still life :)
MintyBeam: Bug a room and transmit voice over a laser beam (also a Super Spy Ear/Stethoscope)
Glowing Slug Blood Experiment
Could be possible to "layer cake" them ?agar -------muck -----agar ------muck -----this could be augment the electricity ?
Look, bro! the reduction actually occurs at the anode surface where it receives the electrons from the bacterial cells or whatever in the mud. The anode receives the electrons found in the mud, the protons passes through the agar-salt to neutralize for charges in both compartments to be received by an electron acceptor, which is oxygen in the demonstrated cell, as water is open to air, thus forming water molecules.
This is awesome, thanks! I'd like to do some more experimenting with the pollution and the bacteria, so does anyone know exactly what type of pollution they respond to in terms of less glowing, and why?
so am i can i have some help with this too?
I'm so happy my instructable is exciting! Isn't science AWESOME!!! And for sure your goldfish could live in the fuel cell because the water and muck are all from typical fresh water habitats that would support fresh water fish! As a neat experiment you could buy some Ph and other water test strips from a pet store and test the fuel cells water quality at the start and a few days after its running to see if the acid levels go up or something before you put a fish in..... Also you can test how doing water changes (to keep the fishtank clean) affect the voltage! There are so many variables and who knows what you might discover!
please respond fast if possible! Thanks
Thanks for the fast response, I am doing a science project on this and I'm SOOOOOO excited. Do you think this would work as a habitat during the experiment for my pet gold fish and my other types of fish that I have? Also great inscrutable! :)
Hey! It prob won't work with sand..... Mud may work but muck from a wet land like a pond or marsh or bog works because it has the GEOBACTER bacteria in it! Ps the fish is only to show how safe the fuel cell is and natural..... It doesn't need the fish!
wow! Great job!!
does it have to be muck or can it be sand or mud?
Does this experiment only work with beta fish or does this work with all types of species of fish?
It gave me around 550mV
Hi is anyone willing to sell me their culture of bioluminescent bactetia? Ive spent 30 agar plates and still cant get any :'( id really like some so please contact me on email@example.com, im offering $10+shipping.
Hi I am doing this for my science fair experiment and I just wondering about the new recipe that makes the vibrio fischeri glow brighter involving calcium carbonate and glycerol? Also what amount of each chemical is needed and is yeast extract included in the recipe? Do you know any other variables that could possibly make the bacteria glow brighter? Thank you
Graphite is better as electrode.
yes you do have to freeze (solidify) it.
its because bacteria need food for their life cycle, try adding glucose or other sugars with it.
