All living organisms need energy to perform various life processes and the source of energy for all living organisms is food. It is available from different sources. There are two types of modes of ...

For species with bicellular pollen, the attrition of pollen tubes is often greatest where the style narrows at the transition between stigmatic tissue and the transmitting tissue of the style. In this ...

Heterotrophic prokaryotes have the capacity to uptake inorganic nitrogen (N) substrates. However, it remains unclear what the potential competition is between heterotrophic prokaryotes and autotrophic ...

Quantifying the contribution of marine microorganisms to carbon and nitrogen cycles and their response to predicted ocean warming is one of the main challenges of microbial oceanography. Here we ...

Scientists at the Weizmann Institute of Science in Israel have generated strains of the bacterium Escherichia coli that consume just CO 2 as their nutrient source, instead of organic compounds. They ...

Scientists could never square theory with data on how certain organisms fixed carbon. Turns out they were asking the wrong ...

This diagram shows how researchers converted a common laboratory sugar eating (heterotrophic) E. coli bacterium (left) to produce all of its biomass from CO2 (autotrophic) by metabolic engineering ...

Over the course of several months, researchers in Israel created Escherichia coli strains that consume CO2 for energy instead of organic compounds. This achievement in synthetic biology highlights the ...
