Which generally engineered microbe was used for nitrogen fixation by incorporating nif gene in cereals

Which microbe is used for ripening of swiss cheese?

Which of the following microbes is used for commerical production of ethanol ?

In genetic engineering which is used for transfer of genes from one cell to another?

Cell in some filamentous cyanobacteria, which is specialised for nitrogen fixation is called

We find that Rhizobium forms nodules on the roots of leguminous plants. Also frankis another microbe forms nitrogen fixing nodules on the roots of non-leguminous plant Alnus. Can we artifically induce the property of nitrogen fixation in a plant-leguminous or non-leguminous?

Structure found in blue green algae which helps in nitrogen fixation is:

A bacterium ashowed mutation and the mutant gene was found to be beneficial for a cereal plant. Secientists isolated the mutant gene and incorported it into the cereal plant. Name the process used and diagrammatically explain it.

Write the scientific name of the microbe used for fermenting malted cereals and fruit juices.

Two microbes found to be very useful in genetic engineering are
