AbstractThe highly optimized natural process of oxygenic photosynthesis leads to the formation of redox equivalents, such as NADPH, that can be used to fuel heterologous biotransformations in phototrophic microorganisms. We investigated the reduction of 2-methylmaleimide by the ene-reductase YqjM in the cyanobacterium Synechocystis sp. PCC 6803 and doubled the productivity of the cells by inactivating flavodiironproteins (FDPs) as competing electron sink under self-shading conditions, reaching 18.3 mmol h−1 L−1.

Physical And Chemical

Cyanobacteria and microalgae are usually found in speleothems, rocks and walls of show caves exposed to artificial lighting. These microorganisms develop as biofilms coating the mineral surfaces and producing aesthetic, physical and chemical deterioration. A wide number of physical, chemical and environmental-friendly methods have been used for controlling the biofilms with different results. Natural biological control has been suggested by some authors as a theoretical approach but without direct evidence or application. Here we report the finding of a natural biological control of phototrophic biofilms on the speleothems of Nerja Cave, Malaga, Spain. The formation of plaques or spots where the phototrophic microorganisms disappeared can be assumed on the basis of processes of predation of bacteria, amoebas and some other organisms on the phototrophic biofilms. This study aims at investigating the potentialities of the biological control of phototrophic biofilms in caves, but the originality of these data should be confirmed in future studies with a larger number of biofilm samples in different ecological scenarios.
