process for increasing the potential of biofuel production from microalgae using bio modulators

摘要

the present invention provides a method of treatment of microalgae culture and isolation of extremophiles and marine environments for optimum production of biodiesel. the species of microalgae used may be a species of the genus dunaliella acidophila (d.bardawil, d., d. biolecta, d. lateralis, d. maritima, d. minuta, d. parva, d. d. polymorpha and d. peircei, primolecta.quartolecta pseudosalina, d., d. tertiolecta d. viridis and others). the culture of microalgae for biodiesel production, the optimum conditions for the production of biomass and lipid are different.the invention provides a method to simultaneously stimulate the accumulation of biomass and intracellular lipid (more than 60% of dry weight), mainly intended for the production of neutral lipid by the action of bio diesel, bio natural modulators. the chemical analogues (auxins, gibberellins, cytoquinines.nacl) and alkaline hypersaline conditions. another aspect of the invention is the application of specific changes in ph of the culture medium resulting in the spontaneous precipitation of lipid loaded cells, once the cycle of growth and lipid storage. born in biodiesel production is completed.this method allows the rapid recovery and low energy, passive seeker and the centrifugation step and filtration, microalgale biomass for extraction of intracellular lipids and their conversion to biodiesel.this method is highly selective culture conditions in which only a specified number of species shows a similar response and / or may be, which reduces the risk of contamination by other microalgae, bacteria and fungi, is a problem "column direct in the cropping systems, such as the open pits.this is a system of culture of microalgae and wide application for the biofuel, and others.
