Two-stage cultivation of N-rich and N-deprived Acutodesmus obliquus biomass: Influence of cultivation and dewatering methods on microalgal biomass used in anaerobic digestion
(
Elsevier
, 2016 , Article)
Microalgae can be manipulated to accumulate certain cellular compounds of interest without the need for genetic modification - simply by controlling growth parameters such as nitrogen (N). Therefore, A. obliquus was ...
Anthropogenic related variations in the epibiotic biodiversity and age structure of the “Pearl Oyster” Pinctada radiata within the eulittoral zone of Qatar
(
Elsevier
, 2016 , Article)
Abstract Oyster aggregations provide critical habitat that contain diverse communities, with epibiota and oysters sensitive to environmental disturbance. The monitoring of oysters and associated organisms has become an ...

The study aimed to confirm the presence of historic oyster banks of Qatar and code the biotopes present. The research also collated historical records and scientific publications to create a timeline of fishery activity. ...
Associated effects of storage and mechanical pre-treatments of microalgae biomass on biomethane yields in anaerobic digestion
(
Elsevier
, 2016 , Article)
The pre-treatment of microalgae cell walls is known to be a key factor to enhance methane (CH4) yields during anaerobic digestion. This study investigated the combined effects of two different biomass storage methods and ...
Macrobenthos in the central Arabian Gulf: a reflection of climate extremes and variability
(
Springer International Publishing
