It is a stair shaped structure made up of 1 m long bamboo tubes, which are tied through two strings of 12 to 15 meters in intervals of 1 meter. These rafts are placed every 3 or 4 meters between them. The juvenile sporophytes similarly adhere at intervals of about 50 cm.The distance between the plants on a string varies between 1.7 to 3.0 cm., while the length of the string ranges from 1 to 3 meters. which contains fertilizer, at a depth of 1.3 meters. Every 6 meters along the raft a porous mud jar of 2.8 lt is suspended. This is to make a single line of about 60 m long. It is built by attaching tubes of rubber or bamboo, extreme with extreme. Otherwise, the growth models obtained in laboratories are used to design them. Unlike laboratory cultures their goal is not to obtain growth data. Photo bioreactors are designed for a micro alga in particular even for an specific application (for example, production of astaxanthin), which doesn´t mean they can’t be used for several species. These devices are used to produce micro algal biomass in quantities of the order of kilogram per day or tons per year. They are intended to produce the massive growth of microalgae. Photo bioreactors are devices where big amounts of algae can be contained. Massive Cultivation of Algae: Photo Bioreactors The models of growth developed in laboratories are a sort of planning tool, which allows to design and operate optimally photo bioreactors or massive cultures of algae. These are the conditions that ensure that large-scale crops can be made, with the necessary resources and without generating significant losses. This is, temperature, pH, light intensity, aeration rate and concentration of nutrients. The culture of these species in laboratories, allows to explore the complex relationships between them and the ideal environment for their reproduction. So, they also help maximize the growth of the population of the algae studied. Experiments in laboratories also allow a bigger knowledge about the optimal conditions of large-scale cultivation, for commercial and technological uses. In this sense, the advantages offered are those of studying them in an isolated environment. The algae cultures in laboratories fulfill an specific function, which is to know and investigate everything related to a single species.
