Spiked agglomerates

[Bosma, Rouke]

> Dear people,
> 
> I had some old (axenic) stock culture of Monodus subterraneus in a shaked flask in a light cabinet (20 °C, 200 umol m-2 s-1) and when looking at the fresh water algae after two months in one of the flasks strange spiked agglomerates (diameter 0.3 - 1 cm) appeared. The medium got completely clear.
> 
> Probably nutrients were limited and maybe it is a surviving strategy for the algae (when putting them in fresh media, from these agglomerates the algae start growing again).
> This should be very interesting to investigate.
> 
> Has anyone seen something like this before ?
> 
> Please contact me, i can then also send a picture to you (not allowed in this mail to the newsgroup)
