glycine metab algae; algae glycine metab; metab glycine algae Abstract: Uptake of glycine-14C was measured in 3 species of blue-green algae, viz., Oscillatoria fasorvensis, Gloeotrichia pisum, and Microcystis aeruginosa. Radioactivity in breis of Oscillatoria increased with increasing time of incubation in glycine-14C soln. (100 mCi./liter distd. water). The rate of uptake increased with the increasing ambient glycine-14C concn., the max. velocity of uptake being 4 * 10-7 moles/g. tissue/hr. The radioactivity lost from the medium is measured quant. as 14CO2 and as much as 15% of radioactivity is lost from glycine-14C at 9 * 10-7 moles/liter. The results indicate positive absorption and assimilation of glycine by blue-green algae as compared to the green alga, Spirogyra.

Richt Accession Number: 5521390 Keywords: Freshwater Q1 01461 Plankton; Q1 01221 General Abstract: The degree of participation of the planktonic blue-green alga Gl. echinulata in the synthesis of organic compds in water reservoirs has been evaluated. The biomass of Gloeotrichia, its photosynthetic activity, chlorophyll content, assimilation number, calorie content and wet and dry weights were determined. The results show that the productivity of Gl. echinulata is significantly lower than that of the smaller lake plankters. Nevertheless, at the high biomass which might be formed by Gloeotrichia in the reservoirs its role becomes significant. Notes: 1969. 11 refs. Records keyed from 1971 ASFA printed journals.

The physical and chemical characteristics of the water drawn from an analysis carried out in the summer (highest growth period of the alga) are mentioned. Subsequently, the sp is described bringing out the biometric values of the heterocyst and spora and pointing out the deep morphologic alterations which the 1st vegetative cells, located behind the spora, undergo in the adult colonies. Finally, the annual growth cycle of the alga was described. Notes: 1969. 0048-8399 24 refs. Records keyed from 1972 ASFA printed journals. Italian

In media with ammonium N the first heterocysts appeared later in comparison with media contg. nitrate. No differences were found in the effect of different forms of nitrate (K nO3,Mg(NO3)2,Ca(NO3)2) or ammonium ((NH4)2SO4) (I), (NH4)2H PO4 (II) (concn. 0-692.5 mg N/l.) on formation of heterocysts. I and II in concn. 27.7 Mg N/P. blocked the formation of heterocysts by Anabaena cylindrica and Nostoc species; for A. hallensis, A. variabilis, Gloeotrichia species, and N. muscorum, the development of heterocysts was observed after considerable delay.

nitrogen fixation algae; algae N fixation; Nostoc photochem redn N; Anabaena photochem redn N Abstract: N fixation and photochem. redn. of elemental N were investigated in 4 blue-green algae: Anabaena cylindrica, A. oscillarioides, Nostoc comminutum, Gloeotrichia natans. About 5-10 mg. dry wt. of algae were inoculated into 100 ml. of the culture medium of Fogg (1949) or that of Allen and Arnon (1955), and incubated for 20 days under continuous illumination of .apprx.400 footcandles at 20-22 Deg. Algal material was centrifuged and dried to const. wt. Total N was detd. by the micro-Kjeldahl technique of Chibnall, Rees, and Williams (1943). Reduced N was supplied as NH4Cl at 1 micromole/ml. of suspension. Results showed that A. cylindrica, A. oscillariodds, and N. comminutum fixed N and photochem. reduced elemental N, while G. natans did not.

KMnO4 was about as effective against all 8 algae species after 4 hrs. of treatment as after 72. Contrastingly, tests of CuSO4.5H2O against the 2 Oscillatoria species and Hydrodictyon showed that changing the treatment time from 4 to 72 hrs. caused large differences in the concn. required to kill these algae. Despite the great variations in susceptibility to CuSO4.5H2O, ranging from 3 blue-green species killed with 0.1 ppm. CuSO4.5H2O to 2 filter-clogging species not killed by 8.0 ppm., treatment with 1-5 ppm. KMnO4 was sufficient to kill 7 of the 8 algae species.

Series B, Biological Sciences Volume: 162 Issue: 989 Pages: 517-534 Date: Jul. 27 Abstract: Following exposure in situ for periods of 3 to 24 h of samples of lake or sea waters to which $^{14}$C-bicarbonate had been added, radioactivity was found in dissolved organic matter in the water as well as in the cells of phytoplankton. The amount in the water was between 7 and 50% of the total carbon fixed in the photic zone of the water column. This production of extracellular $^{14}$C-labelled organic matter was found under a wide variety of conditions and with many different types of phytoplankton community. It thus seems likely that the widely used method, in which fixation of $^{14}$C in particulate matter only is determined, under-estimates total primary productivity. The labelled organic substances in the water are probably liberated by intact photosynthesizing cells rather than by breakage of cells during filtration. Glycollic acid is likely to be one of the principal substances concerned. Over a wide range of light intensities liberation of extracellular products by a given phytoplankton population was proportional to the amount of carbon fixed in the cells, except that it tended to be relatively greater at low light intensities (< 1 kilolux) and at light intensities high enough to inhibit photosynthesis (> 50 kilolux), when as much as 95% of the total organic $^{14}$C might be extracellular. Population density, period of exposure to $^{14}$C-bicarbonate and species differences also affect the extent of excretion. The implications of extensive liberation by phytoplankton of extracellular products of photosynthesis for our understanding of the trophic relationships in aquatic habitats seem to be considerable.

Single vesicles average 75 millimicrons in diameter, range from 0.2 micron to 1.0 micron in length, have conical ends, and are bounded by a single membrane 2 millimicrons wide. The reversible disappearance of gas vacuoles induced by sudden application of pressure is accompanied by a reversible collapse of the individual gas vesicles. Notes: FLA Reports
