BACKGROUND The 'attached cultivation' technique for microalgae production, combining the immobilized biofilm technology with proper light dilution strategies, has shown improved biomass production and photosynthetic efficiency over conventional open-pond suspended cultures. However, how light is transferred and distributed inside the biofilm has not been clearly defined yet. RESULTS In this r...

The primary requirements for high-biomass-concentration microalgal cultivation include a photon source and distribution, efficient gas exchange and suitable growth medium composition. However, for mass outdoor production of microalgae, growth medium composition is a major controlling factor as most of the other factors such as light source and distribution are virtually uncontrollable. This wor...

Algae are an important group of photosynthetic autotrophs and commonly found in different types water bodies, including paddy fields. The algal possesses distinctive characteristics ranges from prokaryotic cyanobacteria to eukaryotic algae. Within these, microalgae unicellular microorganisms widely distributed saltwater as well freshwater environments. Microalgae species have been utilized fiel...

BACKGROUND In plant-derived animal feedstuffs, nearly 80 % of the total phosphorus content is stored as phytate. However, phytate is poorly digested by monogastric animals such as poultry, swine and fish, as they lack the hydrolytic enzyme phytase; hence it is regarded as a nutritionally inactive compound from a phosphate bioavailability point of view. In addition, it also chelates important di...
