Uptake and release of phenol by algal cells. Austin, Tex.: Center for Research in Water Resources, Bureau of Engineering Research, University of Texas, [] (OCoLC) Material Type: Government publication, State or province government publication: Document Type: Book: All Authors / Contributors: Jordi Bofill; Earnest F Gloyna.

The supernatant was evaluated for the remaining phenolic compounds and also the uptake of phenolic compounds in the algal cells after 5 and 10 days was investigated using HPLC. Regarding the uptake of phenolic compounds, only the three best removed compounds were investigated, namely p-coumaric acid, caffeic acid and vanillic acid [ 55 ] (culture conditions are presented above).Cited by: 2.

The rate of incorporation of amino acids into the animal cell is, in general, higher than into the algal cells, with the exception of glycine. The uptake and incorporation of this amino acid into the zooxanthellae of all investigated types of Zoanthus flos marinus is several times higher than into the protein of the respective coelenterate by: The supernatant was evaluated for the remaining phenolic compounds and also the uptake of phenolic compounds in the algal cells after 5 and 10 days was investigated using HPLC.

This book was the first comprehensive collection of techniques for culturing algae. Twenty-eight clearly written chapters by 30 outstanding algologists utilize the work of more than investigators.

On its initial publication, the book became a standard reference in the field. Polyphenol compounds of macroscopic and microscopic algae. algae release phlorotannins into the environmen t; it is also listed in the current edition of the Red Data Book of Ukraine ( Phenols are an important group of natural products with antioxidant and other biological activities.

These compounds play an important role in algal cell defence against abiotic and biotic stress. Several authors have recently published results regarding the total phenol content and antioxidant activity of algae.Cited by: This observation indicated that light illumination might be beneficial for the organics uptake by the algae.

In addition, as mentioned in sectionsome non-algae species were also co-existing in the reactors, which may have higher bioactivities and consume more organic C due to the higher DO levels during the light by:   In this study we tested the hypothesis that metal uptake by unicellular algae may be affected by changes in metal speciation in the boundary layer surrounding the algal cells.

The freshwater alga Chlamydomonas reinhardtii was preacclimated to different N nutrition regimes; changes in N nutrition are known to change the nature of extracellular metabolites (e.g., reactive oxygen species Cited by: 2. 2 Algal degradation of aromatic compounds Heterotrophic studies.

Some species of algae are capable of heterotrophic growth on organic carbon sources. One way of investigating the biodegradation of organic pollutants by algae is to encourage the cells to Cited by: Fig.

5B depicts the change of phenol uptake with time. The phenol uptake increased within first 60 min up to ∼90% of the equilibrium phenol uptake. The order of phenol uptake along the time range decreased as follows: blank copolymeric beads > immobilized algal beads > free algal cells similar to Wu et al.

Second, anemones were homogenized, and the numbers of algal cells were determined by flow cytometry (Guava easyCyte HT 2 laser flow cytometer: EMD Millipore Cited by: 1. A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the : Helmut Fischer.

Blood cells are easily visible through the transparent body as they flow rapidly through the body cavity. To support oxygen transport, Daphnia have the extracellular respiratory protein hemoglobin (Hb), a multi-subunit, multi-domain macromolecule.

There are at least four Hb genes. Daphnia tend to develop more Hb to increase oxygen uptake from Cited by: The kinetics of heavy metal uptake by algal cells involves two stages.

The first phase is very rapid, occurring immediately after initial contact with the cell and usually lasting for less than Algal cells are discarded at the end of a test.

Algae are capable of considerable adaptation to the toxic effects of antimetabolites and antibiotics, such as streptomycin, penicillin, chloramphenicol, sulfanilimide and sodium selenate (Kumar ). It is important to avoid contamination of algal cultures by bacteria.

The endophytic green alga Acrochaete operculata completely colonizes the sporophytes of the red alga Chondrus crispus ; however, it does not penetrate beyond the outer cell layers of the gametophytes.

Given that the life cycle phases of C. crispus differ in the sulfation pattern of their extracellular matrix carrageenans, we investigated whether carrageenan fragments could modulate. Algal Bloom Reduce the Uptake of Toxic Methylmercury in Freshwater Food Webs.

through the dilution of mercury in consumed algal cells. Under bloom dilution, as algal biomass increases, the. Preparation of Cells and Protoplasts for Ci Measurements. For each measurement with nonsynchronized cells of D. tertiolecta an aliquot of high- and low-Ci algae containing about 50 to μg of total Chl was harvested by centrifugation (g, 5 min) and washed three times in 1 mL of CO 2-free buffer (25 mm BTP-HCl, pHcontaining 1 m NaCl).The final pellet was resuspended in a small Cited by: The presence of algae in the aerobic and facultative zones is essential to the successful performance of facultative ponds.

In sunlight, the algal cells utilize CO 2 from the water and release O 2 produced from photosynthesis. On warm, sunny days, the oxygen concentration in the surface water can exceed saturation levels.

Conversely, oxygen.Natural phenols can also be found in fatty matrices like olive oil. Unfiltered olive oil has the higher levels of phenols, or polar phenols that form a complex phenol-protein complex. Phenolic compounds, when used in beverages, such as prune juice, have been shown to be helpful in the color and sensory components, such as alleviating bitterness.
