Introducción. Haematococcus pluvialis es una microalga que produce astaxantina, un betacaroteno y antioxidante muy usado en la industria. Para obtener mayor producción de astaxantina se planteó como Objetivo utilizar diferentes factores estrés, biorreactor a escala laboratorio 5 litros. Metodología. Se cultivó el medio RM, pH 6,8, temperatura 20±2ºC, aire filtrado, iluminación con lámparas blan...
Astaxanthin from Haematococcus pluvialis is commercially produced in a two-stage process, involving green vegetative (macrozooid) and red aplanospore stages. This approach has been scaled up to an industrial process but constraints limit its commercial success and profitability, including: contamination issues, high pigment extraction costs, requirements for high light levels and photo-bleachin...
Esterified astaxanthins are used as functional nutraceuticals and pigments in many food products. Unfortunately, the utilization is currently limited due to their chemical instability and poor water-solubility. In this study, esterified astaxanthins were quantified and purified from Haematococcus pluvialis using a novel and precise approach. By HPLC-(+)APCI-MS/MS, twenty esterified astaxanthin ...
