AB As the commercial use of seaweed for natural product extraction calls for abundant, uniform biomass, this study focused onthe production and the variability of the harvested biomass of valuable compounds produced by a commercially relevantred algal species, Asparagopsis armata. Its tetrasporophyte stage was retrieved from two Irish localities and grown for over2 years in indoor cultures at 13 °C and 17 °C, and bromoform, mycosporine-like amino acids and phycobiliprotein contentswere monitored over time. Growth rates at diferent temperatures were specifc to isolates, and one isolate failed to grow at17 °C. All compounds of interest were detected by the end of the 2-year cultivation period, and most of them were producedat an exponential rate at 13 °C but not at the higher temperature. At 13 °C, bromoform reached concentrations of 10.00 ±0.55 mg g−1, total mycosporine-like amino acids of 2.65 ± 0.10 mg g−1, phycoerythrin of 11.46 ± 0.35 mg g−1 and phycocyanin of 72.13 ± 1.74 mg g−1 in Irish isolates. The observed variability in compound content was statistically signifcantbut not large enough to impede commercial utilization. Bromoform content in cultivated samples was almost 6-fold higherthan in feld-collected samples though natural bromoform variability remains to be elucidated. Our fndings suggest thatthe tetrasporophytic phase of A. armata is a suitable candidate for indoor cultivation; abundant and homogeneous biomasscomposition can be obtained which can be further optimized by growth temperature.
