Default Need help please about a anti microbial test



Dear all,

i need help to understand a result and will be very glad if someone could explain to me the result. the test was made in 26 pieces of bamboo coz i wanted to know how good is the bio agent bamboo kun against bacteria.

I heard that it can kill off 99% of the bacterias without any treatment thanks to the natural agent bamboo kun.

i got the result in logarithm data and the tester can not or is refusing to say how good is the anti bacteria in percentage. All i want to know is in percentage how was the bacteria reduction? like 80% 90%? in some cases i see 99.99%.

I did the JIS Z 2801:2000 test, a japanese standard. anyway, the test is below and i hope someone can help me here, and did any of u ever heard of bamboo kun?

thanks all

Marcus

You need to describe the experiment.

Default Re: Need help please about a anti microbial test

just talked to the guy from SGS and here is the final result and how it was conducted.

In my bamboo piece without any chemical (just the bamboo piece) they placed 25 ml of liquid bacteria which has 10.000 units approximately.

they used a film to wrap it and incubation for 24 hours

after that, they counted the bacteria left which were less than 10 (<10)

so in other words, there was 99.9% reduction as far as i know ^^

anyway, guess thats the final result and exactly what i wanted to know, thanks for the help and i hope u guys have learnt something new about this "Bamboo kun" which kills bacteria and is natural

the reason for this test is that i am releasing a new line of bamboo kitchenware and i want to explain to customers that it has a natural anti bacteria.

Thanks all

Marq.

Wouldn't it be advantageous to run parallel tests on other materials and reach a conclusion that way. Could be that the bacteria died of natural causes.

p.s. some species of bamboo happily grow for years without making a flower, then, when it eventually does, the whole plant dies shortly thereafter. Therefore, the bamboo plant probably contains genes that strongly stall flower development and also cause eventual suicide of the organism. Interesting, that's all!
