In situ, High-Resolution Quantification of CO2 Uptake Rates via Automated Off-Gas Analysis Illuminates Carbon Uptake Dynamics in Cyanobacterial Cultures

This paper develops a low-cost system for high-resolution CO2 uptake rate measurement in cyanobacterial cultures and shows that uptake rates increase linearly then decay to cessation.

Highly Iterated Palindrome 1 (HIP1) sequence improves Synechococcus sp. PCC 7002 transformation efficiencies in a homology- and methylation-dependent manner

This study shows that the HIP1 sequence enhances transformation efficiency in Synechococcus sp. PCC 7002 through homology and methylation-dependent mechanisms.

Delivery of novel replicating vectors to Synechococcus sp. PCC 7002 via natural transformation of plasmid multimers

This paper develops and characterizes two novel replicating plasmids for Synechococcus sp. PCC 7002, showing that multimeric plasmids significantly enhance transformation efficiency.

Heterologous production of cyanophycin with Tatumella morbirosei cyanophycin synthetase

This study identifies Tatumella morbirosei cyanophycin synthetase as highly efficient for heterologous cyanophycin production in E. coli, achieving up to 1.9 g/L in 48 hours.
