Algal growth microalgae

It is out of question that algal biomass can be utilized for the production of various bioproducts. However, significant improvements in the efficiency, cost structure and ability to scale-up algal growth, and lipid extraction are required to establish a commercially viable microalgae-based biorefinery. 

Capacity to treat/utilize wastewater for their growth microalgae used nitrogen and phosphorus, which can be obtained from wastewater. Additionally, algal cultivation does not require herbicides or pesticides application (Rodolfi et al., 2009). 

Marine water nutrients concentration is responsible for phytoplankton structure variation. Therefore, the quantities of organic substance (Table 1) in 2001 and 2002 have triggered growth of non-diatom species, given that most of micro-algal consumers of organic substance are mixotrophic species of microalgae, which predominated in the respective time span. 

In order to assess the volumetric productivity of the system the micro-algal biomass concentration and average specific growth rate need to be known. For the moment it will be assumed that the biomass concentration can be set at any desired level by means of a turbidostat mode of operation. Consequently, only the average specific growth rate of the microalgae in the photobioreactor needs to be calculated. 

Bivalves have a limited capacity to synthesize sterols de novo (Holden and Patterson, 1991) so dietary sterols from microalgae could be important in their nutrition. For post-larval P. magellanicus, the combination of C muelleri with Pavlova spp. produced higher growth rates than other algal diets tested, which was attributed to the comparatively high proportion of cholesterol in sterols from C. muelleri (Milke et al, 2008). Of the other...
