Abstract: Provided are a recombinant microorganisms having a genetic modification that increases the expression of bacterioferritin, a composition comprising the recombinant microorganism for use in reducing a nitrogen oxide concentration in a sample, and a method of reducing a nitrogen oxide concentration in a sample.

Abstract: A method of reducing a concentration of a nitrogen oxide, the method comprising: contacting a microorganism with a nitrogen oxide-containing sample to reduce the concentration of the nitrogen oxide in the sample, wherein the contacting comprises contacting the microorganism with Fe(II)(L)-NOx in a bioreactor, wherein the Fe(II)(L)-NOx is a complex in which a chelating agent, Fe2+, and NOx are chelated, wherein L is the chelating agent, and wherein NOx is a nitrogen oxide ligand.

Abstract: A washing apparatus and control method where the washing apparatus comprises a door configured to open and close the entrance; a tub inside a main body; a diaphragm configured to connect the entrance with the opening; and a drum rotatably provided inside the tub. The washing apparatus includes a door washing nozzle to inject water for a first time in a first section and then to inject the water for a second time in a second section when a washing mode of the diaphragm is entered. The washing mode of the diaphragm including the first section in which the drum in a stopped state is accelerated to arrive at a first target rotation speed less than a second target rotation speed and the second section in which the drum at the first target rotation speed is accelerated to arrive at the second target rotation speed.

The door washing nozzle is controlled to inject the washing water for a first time in a first section and inject the washing water for a second time in a second section when a washing mode of the diaphragm including the first section at which the drum in a stopped state arrives at a first target rotation speed and the second section at which the drum rotated at the first target rotation speed arrives at a second target rotation speed.

Abstract: A control method of a washing machine is capable of safely achieving a tub washing operation control with low power consumption. At the time of performing tub washing, water of which the amount is decided depending on a volume inside a drum and a volume inside a water tub is supplied to the water tub, and the rotation speed of the drum is controlled to be inversely proportional to the volume of the supplied water, thereby efficiently controlling a tub washing operation with low power consumption. Also, the rotation state of the drum is controlled, at the time of performing the tub washing, to maintain the temperature of a motor or a printed circuit board (PCB) to be a predetermined level or less, thereby safely controlling a tub washing operation with low power consumption.
