Pimelodus pictus, also known as the pictus cat or pictus catfish, is a small (11.0 centimetres (4.3 in) TL) member of the catfish family Pimelodidae, native to the Amazon and Orinoco river basins and commonly kept as a pet in freshwater aquariums. Pictus catfish are sometimes mislabeled as Angelicus cats in the aquarium trade, but the latter ...
Description. Many long-whiskered catfishes grow to be very large, including the piraiba, Brachyplatystoma filamentosum, reaching about 3 m (9.8 ft) in length. They have three pairs of barbels, with maxillary barbels that may reach the length of the fish's body. Like many other catfishes, their bodies lack scales. The adipose fin is well developed.
Bacterial growth. Growth is shown as L = log (numbers) where numbers is the number of colony forming units per ml, versus T (time.) Bacterial growth is proliferation of bacterium into two daughter cells, in a process called binary fission. Providing no mutation event occurs, the resulting daughter cells are genetically identical to the original ...
The Monod equation is a mathematical model for the growth of microorganisms. It is named for Jacques Monod (1910–1976, a French biochemist, Nobel Prize in Physiology or Medicine in 1965), who proposed using an equation of this form to relate microbial growth rates in an aqueous environment to the concentration of a limiting nutrient.

Chemostat. A chemostat diagram featuring inflow (feed) and outflow (effluent). Enclosed chemostat vessel with a continuous and adjustable inflow of medium and outflow of effluent, used for controlled growth of microorganisms. The system maintains a constant volume and level of aeration. The growth rate of the microorganism is controlled by ...
bacteria. Biological exponential growth is the unrestricted growth of a population of organisms, occurring when resources in its habitat are unlimited. Most commonly apparent in species that reproduce quickly and asexually, like bacteria, exponential growth is intuitive from the fact that each organism can divide and produce two copies of itself.
