Hey, im sorta new here, ive been here for a little bit now, but havent got around to doing this yet. Im in yr 12 so i will probably do a lot of question asking and very little answering for a long time yet. Im interested in maths and physics, especially dark matter and dark energy. Red Kelly

Thanks CharonY, yeah im looking at at classing 75 to 80% of bacteria killed as effective. I will be testing it within the month, I was looking for some articles for reaerch and background information, i have done a bit of looking but nothing really what i wanted so far, i was wondering if anyone knew anything specific to the topic. Thanks again

Hey, so im doing a biology EEI on finding the lowest effective concentartion of alcohol ( both isopropyl and ethanol individually) against certain bacteria. I have chosen Bacillus subtillis (gram positve) and Rhodospirrillum rubrum (gram negative). I was just wondering if anyone knew any sites on concentrations needed? Ive come across a few, some saying about 50% others saying roughly 70%. Bear in mind i am only in yr. 12, so it cant be too technichal or i will have no chance of understanding. Also i came across a lot of wiki stuff, but ive found its not too reliable so im trying my best to steer clear. Any suggestions? Please and Thankyou.
