Abstract: The invention relates to compositions containing Bacillus sp., optionally with magnetite, useful in methods for collecting algae. The invention also relates to methods for collecting algae by contacting algae and bare maghemite and compositions thereof.

Abstract: The device with biofouling control for monitoring aquatic (or gaseous) environment encloses an environmental sensor instrument in a sensor chamber which programmably opens for allowing direct communication between the sensors and the water of interest for sampling and which is closed after the sampling sequence is completed to create an anti-fouling environment in the sensor chamber by adding a biocide into the chamber and exposing the sensors to the anti-fouling environment for a predetermined period of time. The monitoring device includes a microprocessor which is preprogrammed prior to deployment of the device (and which may be re-programmed from a remote host computer during the deployment) into the aquatic environment and which controls the operation of the entire device for a long deployment (up to several months).
