Cellular and biochemical alterations induced by diesel oil in the brown alga Sa...

The effect of the in vitro acute exposure to diesel oil (0.001%, 0.01%, 0.1%, and 1%, v/v) has been evaluated in the brown seaweed Sargassum cymosum var. stenoplhyllum by determining the contents of photosynthetic pigments, phenolic compounds, and morphological and cellular changes. In vitro cultures of S. cymosum were exposed to diesel oil for 30min, 1h, 12h, and 24h under laboratory-controlled conditions. Chl...

Morphology, ultrastructure and immunocytochemistry of Hypnea cervicornis and Hy...

Based on their morphological and physiological features, red algae comprise a complex and variable group of multiple genera, including Hypnea. In particular, the genus Hypnea J.V. Lamouroux (Cystocloniaceae, Rhodophyta) consists of approximately 54 species, including Hypnea cervicornis and H. musciformis. Lectins were described for both species; however, the localization of these proteins is still unclear. Ther...

Metabolomics of Ulva lactuca Linnaeus (Chlorophyta) exposed to oil fuels: Fouri...

Fossil fuels, e.g. gasoline and diesel oil, account for substantial share of the pollution that affects marine ecosystems. Environmental metabolomics is an emerging field that may help unravel the effect of these xenobiotics on seaweeds and provide methodologies for biomonitoring coastal ecosystems. In the present study, FTIR and multivariate analysis were used to discriminate metabolic profiles of Ulva lactuca...

In vitro exposure of Ulva lactuca Linnaeus (Chlorophyta) to gasoline: biochemic...

Refined fuels have considerable share of pollution of marine ecosystems. Gasoline is one of the most consumed fuel worldwide, but its effects on marine benthic primary producers are poorly investigated. In this study, Ulva lactuca was chosen as a biological model due to its cosmopolitan nature and tolerance to high levels and wide range of xenobiotics and our goal was to evaluate the effects of gasoline on ultr...

Data supporting the role of enzymes and polysaccharides during cassava postharv...

This data article is referred to the research article entitled The role of ascorbate peroxidase, guaiacol peroxidase, and polysaccharides in cassava (Manihot esculenta Crantz) roots under postharvest physiological deterioration by Uarrota et al. (2015). Food Chemistry 197, Part A, 737746. The stress duo to PPD of cassava roots leads to the formation of ROS which are extremely harmful and accelerates cassava spo...

The role of ascorbate peroxidase, guaiacol peroxidase, and polysaccharides in c...

Abstract This study aimed to investigate the role of ascorbate peroxidase (APX), guaiacol peroxidase (GPX), polysaccharides, and protein contents associated with the early events of postharvest physiological deterioration (PPD) in cassava roots. Increases in APX and GPX activity, as well as total protein contents occurred from 3 to 5 days of storage and were correlated with the delay of PPD. Cassava samples sta...
