Description

This quarterly report documents significant achievements in the Enhanced Practical Photosynthetic CO{sub 2} Mitigation project during the period from 7/2/2003 through 10/01/2003. As indicated in the list of accomplishments below we are preparing for the final tests necessary to meet our project goals. Specific results and accomplishments for the third quarter of 2003 include: (1) Bioreactor support systems and test facilities: (A) The solar collector used in the light delivery system showed signs of degradation and hence had to be replaced by ORNL. A set of light readings were taken after the new solar collector was installed. The readings showed ... continued below

Description

This quarterly report documents significant achievements in the Enhanced Practical Photosynthetic CO{sub 2} Mitigation project during the period from 7/2/2003 through 10/01/2003. As indicated in the list of accomplishments below we are preparing for the final tests necessary to meet our project goals. Specific results and accomplishments for the third quarter of 2003 include: (1) Bioreactor support systems and test facilities: (A) The solar collector used in the light delivery system showed signs of degradation and hence had to be replaced by ORNL. A set of light readings were taken after the new solar collector was installed. The readings showed an acceptable light profile. (B) The CRF-2 test system has undergone major improvements to produce the high flow rates needed for harvesting (as determined by previous experiments). The main changes to the system are new stainless steel header/frame units with increased flow capacity and a modified pipe end sealing method to improve flow uniformity, and installation and plumbing for a new high flow harvesting pump. The improvements have been completed and the system is ready for testing. (C) The pilot scale bioreactor is ready for testing pending some information from the CRF-2 tests. (2) Organisms and Growth Surfaces: (A) The shape of the Chlorogloeopsis sp. cells (cyanobacteria) was found to be affected by environmental pH, which may be useful in culture quality control. Besides, the further investigation of this phenomenon suggested that the rate of cell adhesion to glass surface decreases upon medium alkalinization. Thus, harvesting effectiveness may be improved by increasing medium pH up to 9 before harvesting of cyanobacteria from a substratum.
