The combined effects of such toxins on fish are little known. This study examines the activities of microsomal (m) and sol. (s) glutathione S-transferases (GST) from embryos of the zebra fish, Danio rerio at the prim six embryo stage, which had been exposed since fertilization to LPS from different sources. A further aim was to see how activity was affected by co-exposure to LPS and microcystin-LR (MC-LR). LPS were obtained from Salmonella typhimurium, Escherichia coli, a lab. culture of Microcystis CYA 43 and natural cyanobacterial blooms of Microcystis and Gloeotrichia. Following in vivo exposure of embryos to each of the LPS prepns., mGST activity was significantly reduced (from 0.50 to between 0.06 and 0.32 nanokatals per mg (nkat mg-1) protein). sGST activity in vivo was significantly reduced (from 1.05 to between 0.19 and 0.22 nkat mg-1 protein) after exposure of embryos to each of the cyanobacterial LPS prepns., but not in response to S. typhimurium or E. coli LPS. Activities of both m- and sGSTs were reduced after co-exposure to MC-LR and cyanobacterial LPS, but only mGST activity was reduced in the S. typhimurium and E. coli LPS-treated embryos. In vitro prepns. of GST from adult and prim six embryo D. rerio showed no significant changes in enzyme activity in response to the LPS prepns. with the exception of Gloeotrichia bloom LPS, where mGST was reduced in adult and embryo prepns. The present study represents the first investigations into the effects of cyanobacterial LPS on the phase-II microcystin detoxication mechanism. LPS prepns., whether from axenic cyanobacteria or cyanobacterial blooms, are potentially capable of significantly reducing activity of both the s- and mGSTs, so reducing the capacity of D. rerio to detoxicate microcystins. The results presented here have wide ranging implications for both animal and human health. [on SciFinder (R)] Notes: CAN 137:364674 4-5

Freshwater Q1 01226 Physiology, biochemistry, biophysics Abstract: The Rivularian cyanophytes are ubiquitous in distribution and attracted attention of cyanobacteriologists as nitrogen fixing organisms. Earlier more emphasis has been given on the morphological studies either from nature or from culture, whereas less attention has been paid on physiological characterization of this particular group. From this family, ten strains (Calothrix-7 species, Gloeotrichia-2 species and Dichothrix-1 species) have been selected and isolated in axenic cultures. Parameters used for physiological characterization were biomass production (dry weight, specific growth rate, generation time); nitrogen fixation (total nitrogen, nitrogenase activity); pigment composition (chlorophyll a, carotenoids, phycobilins) and cellular constituents (carbohydrates, protein). Calothrix -67 and Gloeotrichia-42 showed better biomass production; Calothrix-11, Calothrix-67 and Gloeotrichia-42 showed better nitrogen fixation. Similarly these three strains also showed better protein content, while Dichothrix-371, Gloeotrichia-379 and Calothrix-121 showed better carbohydrate content.

Micromycetes which were used for the bioassay were Fusarium oxysporum, F. moniliforme, F. gibbosum, F. culmorum, F. graminearunt, F. avenaceum, F. sporotrichiella, F. solani, F. javanicum, F. longipes, and also Bipolaris sorokiniana, Rhizoctonia solani, and Alternaria alternata. F. oxysporum proved to be the most sensitive fungus and was used for more detailed analyses. The strongest inhibitory activity of the cyanobacteria tested was found with Calothrix braunii, Tolypothrix tenuis, Spirulina platensis, Oscillatoria sp., Hapalosiphon fontinalis, Gloeotrichia natans, and Lyngbya limnetica. It was shown that the major activity was retained in the cyanobacterial cells. Only very little activity was found in the culture filtrates suggesting that excretion of antifungal compds. by these cyanobacteria is of minor importance. The antifungal compds. of cyanobacteria could be extd. with 60% aq. methanol and were also found in exts. of dichloromethane. [on SciFinder (R)] Notes: CAN 136:147742 10-5

In in-situ expts., PO43- and NO3- were added to all enclosures, but pelagic colonies of G. echinulata only increased in abundance in enclosures to which Fe was also added. An even greater increase in abundance of G. echinulata occurred in enclosures in which PO43-, NO3-, and Fe addns. were complemented by adding B. B addns., together with PO43- and NO3- but without Fe, did not stimulate G. echinulata growth. [on SciFinder (R)] Notes: CAN 135:261747 61-1

E. Smith) Richter from lake sediments and from epilimnetic water show that phosphorus accumulated from the sediments by benthic colonies plays an important role in the development of planktonic populations, whereas uptake from epilimnetic water by vegetative colonies is insignificant. During the spring and summer of 1996, the cellular phosphorus quota of both benthic and epilimnetic Gloeotrichia colonies was monitored in the oligotrophic Peninsula Lake, central Ontario, Canada, in order to detect signs of luxury uptake and subsequent utilization during growth. Assays were also used to measure the rate of phosphorus uptake from the sediment and from lake water. G. echinulata, which overwinters in the form of the benthic akinete packets, is capable of obtaining phosphorus directly from the sediments following germination in early summer, and subsequent growth in the epilimnion is based almost entirely on accumulated reserves.
