Abstract
A novel enhanced surface area conico-cylindrical flask (ES-CCF) providing increased surface area by virtue of its' inner arrangement and useful in routine small-scale studies of bioactives production by any biofilm-forming marine as well as terrestrial microorganisms. Compared to corresponding Erlenmeyer flask of similar volume the ES-CCF provides more than 80% additional surface for biofilm attachment and growth. The ES-CCF does not require steam sterilization and is durable as the device is constructed of polymethyl methacrylate or any other such hydrophobic material and offers possibility of altering the nature of the growth surface (hydrophilic and hydrophobic). The ES-CCF also provides external aeration like a bioreactor, thus increasing the versatility of applications. Further, the device can be operated as a cylindrical flask, that is without the inner arrangement.
