The scalability of microalgae growth systems is a primary research topic in anticipation of the commercialization of microalgae-based biofuels. To date, there is little published data on the productivity of microalgae in growth systems that are scalable to commercially viable footprints. To inform the development of more detailed assessments of industrial-scale microalgae biofuel processes, thi...

abstract this study was performed to compare the efficiency of 6 microalgae namely dunaliella tertiolecta, tetraselmis suecica, chlorella sp., (green algae), nannochloropsis oculata, spirolina sp.(blue-green algae) cheatocerus sp. (diatoma),  and isochrices sp. (haptophytae) on the growth, survival and reproduction efficacy in artemia urmiana in laboratory conditions. artemia cysts were harvest...

Microalgae consume carbon dioxide for their growth and to produce secondary metabolites. One of the control system challenges is to maximize this carbon dioxide consumption by controlling microalgae growth, and by maintaining its growth rate at an optimal value. However, there is no such thing as a microalgae growth rate sensor. This paper proposes a software sensor for the specific growth rate...

regarding increasing rate of drug resistance among microbial pathogens, a global search to find new antimicrobial agents from natural compounds with fewer side effects has been considered by many researchers worldwide. bioactive compounds with good antimicrobial activity have been isolated from different algae and cyanobacteria. the current study was performed to determine antimicrobial potenti...

Acid mine drainage(AMD) contains high concentrations of heavy metals and has become a serious environmental problem. A pipes inserted microalgae reactor(PIMR) was constructed to cultivate microalgae and purify AMD. The effects of metal concentration, pH and sulfate after pretreatment on the removal of iron and microalgae growth were investigated. Batch studies showed that PIMR and microalgae ca...

background: microalgal lipid is a promising feedstock for biodiesel production. the aim of the present study was to investigate the effects of cultivation temperature on the growth and lipid accumulation properties of nannochloropsis oculata microalgae. methods: nannochloropsis oculatacan grow in a wide range of temperatures (5 ~ 35°c). late in the stationary growth phase of microalgae, biomass...

Plant growth-promoting bacteria (PGPB) of the genus Azospirillum are known to enhance the growth of numerous agricultural crops. We are proposing the use of these bacteria as “microalgae-growth promoting bacteria” (MGPB) to enhance the cleaning capacity of polluted water by the freshwater microalgae Chlorella vulgaris and C. sorokiniana. Deliberate inoculation of Chlorella sp. with a terrestria...

This study evaluates the nutritional value of several species of freeze-dried microalgae used to feed the seed of Ruditapes decussatus. These microalgae were: Isochrysis galbana, clone T-ISO; Tetraselmis suecica; and Phaeodactylum tricornutum. The addition of antibiotics, kaolin and fresh microalgae to the freeze-dried diet was also evaluated, and a study was made of the nutritional value of on...

A greater insight on the control of the interactions between microalgae and other microorganisms, particularly bacteria, should be useful for enhancing the efficiency of microalgal biomass production and associated valuable compounds. Little attention has been paid to the controlled utilization of microalgae-bacteria consortia. However, the studies of microalgal-bacterial interactions have reve...
