Detailed explanation-1: -Photochemical transformation of organic materials due to exposures to visible or ultraviolet light wavelengths have been shown to increase bacterial growth rates in some ecosystems [69] and are at least one mechanism that could influence bacterial growth under strong daylighting.
Detailed explanation-2: -Both plants and bacteria will keep nutrients lower and prevent algae from growing. Bacteria also decompose the suspended organic matter. To make this work, you need to have enough beneficial bacteria. Manufacturers are quite happy to sell you these bacteria in a fancy jar with a fancy name: “beneficial” pond bacteria.
Detailed explanation-3: -In general, the higher the temperature, the more easily microorganisms can grow up to a certain point. Very high and low temperatures both obstruct the enzyme processes microorganisms depend on to survive.
Detailed explanation-4: -In dark rooms, about 12 percent of bacteria, on average, were able to reproduce, the researchers at the University of Oregon found. But in sunlight, only 6.8 percent thrived. That was down to 6.1 percent for bacteria exposed to UV light.
