Effect of specific irradiance on productivity and pigment and protein production of Porphyridium purpureum (Rhodophyta) semi-continuous culture.

Porphyridium purpureum is a promising microalga species due to the content of various valuable compounds. In this study, specific irradiance parameter, representing the amount of light energy per unit of microalgae biomass, was introduced. The growth characteristics and pigments and protein accumulation of P.

Growth and B-Phycoerythrin Production of Red Microalga (Porphyridiales, Rhodophyta) under Different Carbon Supply.

Red microalga (Bory) Drew is a well-known object of biotechnology due to its unique ability to synthesize a wide range of biologically active compounds. Enough minerals in an accessible form in a medium are a prerequisite for maintaining a high growth rate of . Carbon is the main element of microalgal biomass and is a component of all organic compounds.

Productivity and morphometric parameters of the microalga IBSS-2 under pilot cultivation in continental mid-latitude climate in spring.

In this study, we aimed to investigate the taxonomy and various characteristics of IBSS-2 strain and describe its cultivation potential in mid-latitude climate during springtime. In addition, our analysis confirmed the essentiality of combining morphological, physiological, and other characteristics when identifying new species and strains of the genus , along with the molecular marker (internal transcribed spacer (ITS) of rDNA gene). The pilot cultivation of microalgae during the springtime in the south of Russia demonstrated that the climatic conditions of this region allow cultivation for biomass accumulation during this season, highlighting light and temperature conditions as the main factors determining the growth rate of .
