Evolution of Macrocystis spp. (Phaeophyceae) as determined by ITS1 and ITS2 sequences

open access: yes, 2001
Macrocystis (Lessoniaceae) displays an antitropical distribution, occurring in temperate subtidal regions along western North America in the northern hemisphere and throughout the southern hemisphere.

Severity and certainty metric for kelp stressors: A tool for research, management, and conservation

open access: yesEcological Indicators
Foundation species face multiple threats, and many are in decline worldwide. Kelps are no exception, with declines documented throughout their range. Stressors such as warming, eutrophication, and reduced water quality—often linked to human activities ...

The effects of ocean acidification on photosynthesis, growth, and carbon and nitrogen metabolism of Macrocystis pyrifera [PDF]

open access: yes, 2016
Increases in atmospheric CO2 concentrations due to anthropogenic activities also cause an increase in oceanic CO2(aq), which will lead to a decline of 0.3-0.4 pH units in the surface ocean by 2100, termed ocean acidification (OA).

Reducing the consumption of fresh water in the process of alginate extraction using Macrocystis pyrifera (Phaeophyta, Laminariales), by recirculating the residual liquids from the pre-extraction and precipitation

open access: yesCiencias Marinas, 1992
The recirculation of the residual liquid from the pre-extraction stage and precipitation using samples of Macrocystis pyrifera was studied to reduce the consumption of fresh water in the process of alginate extraction in the laboratory. An average yield

Macrocystis pyrifera: substrate for the production of bioactive compounds

open access: yesJournal of Applied Phycology, 2019
In recent decades products of marine origin have been the subject of intense investigation; new substances with pharmacological and nutraceutical properties have been discovered. On the other hand, processes more economical and friendly to the environment to produce biocompounds are needed.

Batch and continuous flow systems during the acid pre-extraction stage in the alginate extraction process

open access: yesCiencias Marinas, 1995
Acid pre-extraction in the production process of alginates was investigated in two stages using Macrocystis pyrifera as raw material. In the first stage, the possibility of reducing the normality of the hydrochloric acid used in a continuous flow system
