THE fourth Pedler Lecture of the Chemical Society was delivered by Prof. Hans Fischer at the Royal Institution on February 22, his subject being the constitution of chlorophyll A. Prof. Fischer has been working on blood and leaf pigments in Munich for a number of years, and has recently ...

total nitrogen, total phosphorus, ammonia, high manganese on permanganate index, chemical oxygen demand, fluoride, biological oxygen demand, nitrate, nitrite, phosphate solubility and chlorophyll a) were monthly investigated at seven sites in Taihu Lake between January and December of 2013 in our study...
Earlier we have shown by in vitro reconstitution experiments that the pigment composition of the chlorophyll alb -binding light-harvesting complex of the green alga Chlorella fusca could be altered in a relatively broad range (Meyer and Wilhelm 1993). In this study we used these reconstituted compl...
1. Hypotonic treatment of Phaeodactylum tricornutum cells results in disappearance of their Hill activity; at the same time chlorophyllase activity becomes apparent. Aged cells lyse completely: their pigmented membranes (Whole Membranes, WM) are released. The release of WM ist retarded by Mg". Chlo...
During the week of 20 June 1977 we conducted a week-long chlorophyll mapping experiment in central Long Island Sound. The objective of this experiment was to examine the horizontal distribution of chlorophyll a within the upper water column and to infer the relative importance of biological and ...
Chlorophyll and carotenoids Using the dimethyl sulfoxide (DMSO) method described by Garg59, the chlorophyll and carotenoid content were determined. Briefly, 50 mg of fresh leaf tissue, cut in pieces of approximatively 1 × 1 cm, were placed in a tube containing 7 mL DMSO, and incubated ...
Chloroplast, structure within the cells of plants and green algae that is the site of photosynthesis. Chloroplasts are a type of plastid that are distinguished by their green color, the result of specialized chlorophyll pigments. In plants, chloroplasts
RESULTS: The size structure of the community did not show significant relationship with chlorophyll-a concentration (p > 0.05), but it was associated to the increase in fish density during the dry season. The percentage of individuals with intermediate sizes (301 to 600 µm), in both ...
The blue-shifted Lhca2 paralogue and chlorophyll b enrichment relative to flowering plants make the P. patens PSI–LHCI spectroscopically unique among other green-lineage supercomplexes. Overall, the structure represents an evolutionary intermediate PSI with the crescent-shaped LHCI common in vascular ...
