Algae biofilm growth and the potential to stimulate lipid accumulation through nutrient starvation

Factors affecting algae biofilm growth and lipid production: A review

“…Of the work that has been done on algae biofilms for biofuel production, much of it revolves around the study of the attachment, and subsequent growth, of algae biofilms to various growth materials [14,[16][17][18][19][20][21][22][23]. There has also recently been a significant amount of algae biofilm research on novel reactor designs studying biomass and lipid production rates [14,[17][18]20,21,[24][25][26][27][28][29]. Other studies on algae biofilms have related not specifically to biofuel and bioproduct production, but rather, on using them to treat wastewaters of nitrogen and phosphorus using algal turf scrubbers and novel biofilm growth systems [5][6][30][31][32][33][34][35][36][37][38].…”

Microalgae production in a biofilm photobioreactor

“…Based on this comparison, the suspension performed twofold better than the biofilm. Nevertheless, the current number of studies is limited, and it is likely that lipid productivity in biofilms can be further increased in the future by optimizing the accumulation strategies towards biofilm cultivation, for example, by solving the problem of biofilm detachment initiated by the nitrogen starvation phase (Schnurr et al 2013). Cultivated on wastewater containing BOD and TSS, which likely enhanced the productivity General discussion Light stimulates the growth of phototrophic biofilms.…”

Overexpression of the soybean transcription factor GmDof4 significantly enhances the lipid content of

“…To date, genetic engineering, is more promising for increasing the lipid content of microalgae than controlling the nutritional or culture conditions; the latter has been used to increase the lipid content in several microalgae, but the cell growth was severely limited [14,15]. Many encouraging efforts have been reported for the genetic improvement of the lipid content in microalgae.…”
