    "Efflorescence is a crystalline deposit of salts that can form when water is present in or on brick, concrete, stone, stucco or other building surfaces. It has a white or greyish tint and consists of salt deposits that remain on the surface after the water evaporates. In addition, efflorescence can appear as a powdery substance on floors and walls and requires special care to treat."

    "Efflorescence is a type of salty deposit that is most likely to occur on the surface of the bricks. Efflorescence can be avoided by making sure to use clean water when making the cement. This can only occur when the water contains dissolved salt and it is brought to the surface of the masonry. The water then evaporates and the salt is then left on the surface of the bricks."

    "In chemistry, efflorescence is the migration of a salt to the surface of a porous material, where it forms a coating. The essential process involves the dissolving of an internally held salt in water, or occasionally in another solvent"

    "Hi, it depends, pharmaceutical it is bacterial growth. In construction it is mould. In sandstone or tile it is mould in the joints due to dampness on the floor.
    I hope it helps"
