Microcystins (MCs) are potent hepatotoxins, and their presence in water bodies poses a threat to wildlife human populations. Most of the available information refers plankton, much less is known about microcystins other habitats. To broaden our understanding environmental distribution this group toxins, we conducted extensive sampling throughout Spain, under range conditions distinct aquatic terrestrial More than half tested strains were toxic; concentrations hepatotoxin low compared with...
Forty unicyanobacterial cultures of the genus Scytonema, isolated from terrestrial habitats worldwide (Europe, America, Southeast Asia, Australia and Africa), were investigated. The pigments detected four phycobiliproteins (allophycocyanin, phycocyanin, phycoerythrocyanin phycoerythrin), scytonemin, six carotenoids (β-carotene, canthaxanthin, echinenone, isozeaxanthin, myxoxanthophyll zeaxanthin) and14 different mycosporines, including shinorine, stanierine asterina-330. Cluster analyses...
Summary The antagonist ability of four fungal endophytes isolated from elms ( T richoderma atroviride GF 13, D iaporthe eres 2, iplodia ulmi 5 and Alternaria alternata 6) two fungi a collection harzianum virens ) was evaluated against six strains O phiostoma novo‐ulmi (1, 10, 19, 32, 43 ‐ V a), the causal agent Dutch elm disease. Dual culture tests were established in PDA MA media to test interactions between pathogenic potential ones. showed varying levels capacity . Among them, had...
As part of an extensive study the caves and abrigos Murcia province (SE Spain), first floristic environmental data for chasmoendolithic algae in cave-like environments are presented. Seven two were studied. Photosynthetic active radiation, relative humidity temperature measured over a period 2 years. 18 identified: Bacillariophyceae, 15 Cyanophyceae 1 Xanthophyceae. The most diversified taxa Gloeocapsa with three Chroococcidiopsis Leptolyngbya different species.
Under natural conditions, Chroothece richteriana synthesizes a fairly high proportion of fatty acids. However, nothing is known about how environmental changes affect their production, or the production protective compounds, when colonies develop under full sunshine with levels UV radiation. In this study, wild C. were subjected to increasing temperature, conductivity, ammonium concentrations and photosynthetically active radiation ( PAR ), radiations assess potential in lipid composition...
As part of an extensive study the caves and abrigos Murcia province (SE Spain) floristic environmental data for La Serreta cave are presented first time. This is 30 m deep, 11 high, 9 wide located in a karstic region. Photosyntetic active radiation, relative humidity temperature were measured over period of2 years, values fluctuating between 0.1-1,241 μE.m -2 .s -1 , 16.5-81.8% 9.0-32.4 °C respectively. 18 epilithic algae identified: 2 Bacillariophyceae, Chlorophyceae, Cyanophyceae 5...
In the present study, Triton X-114 (TX-114) is used to extract and partially purify alkaline phosphatase (ALP) from a membranous fraction of Arthrospira platensis Gomont containing cell wall, plasma membrane, thylakoids, sheath. TX-114 has double effect: solubilizing components liberate enzyme and, after phase partitioning, removing chl other pigments in crude extract. The recovery aqueous suggests overall hydrophilic character this enzyme. ALP was kinetically characterized at pH 11.0 using...
Cave wall paintings in Murcia are of worldwide archaeological interest because they some the few surviving artistic testimonies socio-economic reality European pre-history. However, recent years an increase microflora around and occasionally covering partially or totally has been observed. In our study fifty-two algal taxa were identified, among which Cyanophyceae predominated, followed by Bacillariophyceae, Xanthophyceae Chlorophyceae. Extreme values Photosynthetic Active Radiation,...
The presence of Asterocapsa in a low altitude cave Southeastern Spain is reported. All the species genus have previously been collected high mountains or tropical countries. Some seems to be linked dripping water and karstic caves percolation frequent. life cycle, morphology, ultrastructure main environmental characteristics its habitat are studied.
