kombucha, kefir whey

[Guest guest]

Hi I have some q's hoping someone can help me with

1) Can I use kefir whey in all the recipes calling for whey?

2) With the kombucha, i've been making it about a month in a big pot

with tap for continuous fermentation. when i look at the top of the

culture it is not one colour or consistency but has some areas which

are white and look as if they are something else growing. Someone

recently told me that you can get other bacteria growing with the

kombucha that can make you really sick so I'm a bit paranoid that

something else might be growing in there. Any opinion?

thanks
