    Notes: [Auszug] A possible explanation of these results is that salicylate interferes with oxidative phosphorylation processes and inhibits the synthesis of high-energy phosphate bonds. Support for this view is provided by the similarity between the effects of salicylate and 2 : 4.dinitrophenol, which is known to ...

    Profiles of photosynthetic pigments in the ocean using thin-layer chromatography (1974)
    Springer
    Marine biology 26 (1974), S. 101-110 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Phytoplankton pigments at a coastal station off Sydney, Australia, were studied by cellulose thinlayer chromatography. The chromatographic procedure distinguished chlorophylls a, b and c, chlorophyllide a, pheophytin a and pheophorbide a, and the major carotenoids carotene, astaxanthin, fucoxanthin, peridinin, diadinoxanthin and neoxanthin. Chlorophyllide a and pheophorbide a were the most significant chlorophyll-a degradation products in the water column, chlorophyllide a coming from chlorophyllase activity of senescent diatoms, and pheophorbide a from faecal pellets of copepods. Chlorophyll c occurred in every sample, even where there was no trace of chlorophyll a. Because of the greater chemical and biological stability of chlorophyll c compared to chlorophyll a, high chlorophyll c:a ratios result from a large proportion of senescent or detrital material in the samples. Determining the position of patches of copepods, diatoms, green algae and dinoflagellates in the water column was easily done by noting the presence of definitive pigments on the chromatograms.

    A report of green algal pigments in the Central North Pacific Ocean (1976)
    Springer
    Marine biology 37 (1976), S. 33-37 
    Details
    ISSN: 1432-1793
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Thin-layer chromatography showed that chlorophyll b was present in acetone extracts of 6 samples of suspended matter collected in February 1973 from the Central North Pacific Ocean. Pigment patterns showed the presence of green algae and diatoms through most of the euphotic zone down to 200 m. Ratios of chlorophyll b:a ranged from 0.2 to 0.5 at 5 and 100 m depths, but were less than 0.05 at 200 m.

    Notes: Abstract Three species of microalgae commonly used in mariculture —Isochrysis sp. (clone T.ISO) Parke,Pavlova lutheri (Droop) Green andNannochloropsis oculata (Droop) Green — were grown in batch and semicontinuous modes to compare their biochemical composition and production rates. In batch mode, logarithmic-phase cultures of all species had high levels of protein (25.2 to 41.1‰) and low levels of carbohydrate (7.1 to 10.3‰) and lipid (8.8 to 14.9‰). At stationary phase, cultures ofIsochrysis sp. (clone T.ISO) andN. oculata contained significantly less protein (21.8‰ and 20.3‰, respectively), all species contained more carbohydrate (14.8 to 30.6‰), andP. lutheri contained more lipid (16.6‰). In semi-continuous mode, cultures maintained at late logarithmic-phase contained more carbohydrate,Isochrysis sp. (clone T.ISO) contained less protein, andP. lutheri more lipid than logarithmic-phase batch cultures of the same species. Neither growth phase nor harvest regime affected the amino acid composition of the microalgae significantly. However, the concentration of proline inN. oculata was higher in batch cultures in logarithmic phase (9.4‰), than in either semi-continuous cultures in logarithmic phase (5.8 to 7.9‰) or batch cultures in stationary phase (5.6 to 5.9‰). The production rates from batch and semi-continuous logarithmic-phase cultures were not significantly different for any of the species, and there were only minor differences in the production rates of the species (range 12.4 to 17.1 mg algae dry weight 1−1 d−1). The different culture and harvest regimes produced significant differences in the proportions of protein and carbohydrate in the microalgae. Which regime is chosen for culturing these microalgae as food will depend on the nutritional requirements of the animal species being fed.

    The amino acid and gross composition of marine diatoms potentially useful for mariculture (1995)
    Springer
    Journal of applied phycology 7 (1995), S. 521-527

    Notes: Abstract The amino acid and gross compositions of three benthic diatoms (Cylindrotheca fusiformis Reimann and Lewin, Navicula jeffreyi Hallegraeff et Burford and Nitzschia closterium (Ehr. W. Smith) and three chain-forming diatoms (Lauderia annulata Cleve, Skeletonema costatum (Greville) Cleve and a tropical Skeletonema sp. (CS-252)), were determined during late-logarithmic growth phase. Four of the six species were rich in protein, ranging from 31% (S. costatum) to 38% (N. closterium) of the dry weight, and contained 4.9 to 6.5% carbohydrate and 9.4 to 18% ash. The other two species, C. fusiformis and L. annulata contained only 16% protein but had nearly twice the total carbohydrate (11 to 12%) and two to three times the ash (29 to 35%) of the other species. All species contained a similar percentage of lipid (18 to 20%), and a high protein quality based on their total amino acid composition. The usefulness of these diatoms for mariculture will be determined by growth rates, gross composition and acceptability to the animal. N. closterium had the fastest growth rates of the benthic mat-forming diatoms, it was rich in protein, and it may be a good candidate for abalone culture. The two Skeletonema spp. had the fastest growth rates of the chain-forming diatoms, and are already widely used for prawn larval culture in Australia. Feeding trials are now necessary to confirm the high nutritional value of these diatom species for specific animals.
