Accumulation of Astaxanthin Was Improved by the Nonmotile Cells of Haematococcus pluvialis

open access: yesBioMed Research International, 2019
The current commercial production of natural astaxanthin is mainly carried out using Haematococcus pluvialis vegetative cells in the “two-stage” batch mode. The motile vegetative cells are more sensitive to stress than nonmotile vegetative cells, thereby affecting the overall astaxanthin productivity in H. pluvialis cultures. In this study, we compared

Scaling-up of Haematococcus pluvialis production in stirred tank photobioreactor

open access: yesBioresource Technology, 2020
The objective of this study was to evaluate three most common scale-up criteria for Haematococcus pluvialis production from cultivation bottles to 2 and 10 L of stirred tank PBRs. Constant volumetric power input (P/V) was found to be the most suitable criterion for H. pluvialis production. Total carotenoid amount per biomass concentration in 2 L and 10

Haematococcus pluvialis alginden astaksantin üretimi

open access: yes, 2020
Astaksantin, kırmızı renkli doğal karotenoid pigmentidir. Özellikle kabuklu deniz canlıları ve mikroalglerde bulunur. Yapılan çalışmalar, en verimli astaksantin kaynağının Haematococcus pluvialis türü mikroalg olduğunu göstermektedir. Bizim çalışmamızda da bu mikroalg türünden faydalanılmıştır.Haematococcus pluvialis türü mikroalg öncelikle laboratuvar
