Foam flotation can remove and eradicate ciliates contaminating algae culture systems

Harvesting of algae by froth flotation.

A highly efficient froth flotation procedure has been developed for harvesting algae from dilute suspensions. The method does not depend upon the addition of flotants. Harvesting is carried out in a long column containing the feed solution which is aerated from below. A stable column of foam is produced and harvested from a side arm near the top of the column. The cell concentration of the harv...

Can we eradicate Cysticercosis?

Man is the only known definitive host of the tapeworm Taenia solium and becomes a carrier by eating undercooked pork contaminated with “Cysticercus cellulosae” (cysticerci). Pigs act as intermediate host and acquire cysticercosis by ingestion of eggs or proglottids from human feces, which develop into cysticerci within tissue mostly without causing clinical symptoms in the host. Cysticercosis o...

Parasites in algae mass culture

Parasites are now known to be ubiquitous across biological systems and can play an important role in modulating algal populations. However, there is a lack of extensive information on their role in artificial ecosystems such as algal production ponds and photobioreactors. Parasites have been implicated in the demise of algal blooms. Because individual mass culture systems often tend to be unial...
