Default Is this mold?

Hey guys. Brewing an Oktoberfest beer for the first time. Sanitized all equipment as best as I could. Can you tell me if this is mold or krausen? I'm thinking mold. Here is the picture link:

If it's mold, I read from other posts that I could possibly just rack it from below the mold. Is that what you would recommend? Would adding any sort of chemical help while still maintaining the integrity of the beer?

Little hard to see. The hazy bubble look makes it seem like lacto, but it could also just be normal yeast colonies and bubbles with the glass making them look hazy in the pic.

What is lacto? Here is a clearer picture if it helps - http://lh4.ggpht.com/_J8pi3ocEFso/TK...2/IMG_4028.JPG

Lacto is a strain of bacteria that is used to make sour beers (Lactobacillus). It doesn't look like mold, but it is a bit hard to tell in the pics. Looks like it is a sheen across the top of the wort. Is that how it is?

It is mostly a sheen, but a couple of little globular balls are there as well, which is what made me think mold.

In that picture it just looks like yeast rafts or a new krausen forming in the neck. Not an infection.

Ok, well since all three of you seem to think it is not mold, I'm hoping I'm safe. I'll just use a sanitized spoon to scoop it off when i bottle it and then rack it from the center of the carboy. Thanks for your help

How does it smell? If it smells alright how does it taste? If it tastes fine and it's at FG I'd bottle or keg in right now before it gets worse. It could be acetobacter. If it is you will have some vinegar floating on top of it.

Just rack from under it. No reason to take it off the top. If its yeast, then most of it will fall or cling to the sides anyway.

I'm bottling it tomorrow. I'll smell it and taste it tomorrow and report back.
