Biomass and lipid production of marine microalgae using municipal wastewater and high concentration of CO2

Photoautotrophic hydrogen production by eukaryotic microalgae under aerobic conditions

“…The initial partial pressures of both CO 2 and O 2 ranged from 5 to 15%, and atmospheric conditions were also investigated. The specific growth rate (m) was calculated as described by Jiang et al 24 Hydrogen and oxygen measurements. H 2 and O 2 in the headspace of the serum bottles was periodically measured using a GC-14 gas chromatograph (Shimadzu, Kyoto, Japan) equipped with a thermal conductivity detector and a molecular sieve 5A 80/100 column, using Ar as a carrier gas.…”

New technologies from the bioworld: selection of biopolymer-producing microalgae

“…In this case, it is believed that the biopolymer may have been consumed, because after the 10th d of cultivation, the yield of biopolymers was reduced (Table 1). Another nutrient that may have had an influence was nitrogen, whose release in the culture medium from amino acids of phycobiliproteins and chlorophyll can possibly allow cell maintenance to occur [30,31] . The cyanobacterium Nostoc ellipsosporum presented a cell concentration less than the others but had higher efficiency (Table 1) and crude biopolymer yield (Table 2).…”

Can Microalgae Act as Source of Preservatives in Food Chain?

“…The wastewater, after previous treatment (physical and/or chemical) can be used only or as an additive to microalgae cultivation [55,56]. Furthermore, wastewater can be used for microalgae cultivation in open or closed systems because it contains abundant nutrients (sources of nitrogen, phosphorus, carbon, among others), which are necessary for microalgae biomass production.…”
