AB  - Loess is the most important archive of Quaternary palaeoclimate evolution, with more thorough and systematic investigations carried out in the past two decades in the Carpathian Basin. Application of novel proxies in loess research could improve the state of knowledge of the past climatic changes. In order to examine the feasibility of cyanobacterial pigments to be used as biomarkers in paleoclimate reconstruction and thereby substantiate the presence of cyanobacterial community during loess accumulation, geochemical evidence of cyanobacteria-specific biomarkers in the sediment is required. In this study structurally different cyanobacterial metabolites were examined for their potential to be used as biomarkers. These compounds included scytonemin wavelength equivalent (SWE) and mycosporine wavelength equivalent (MWE) compounds. The effect of various physico-chemical factors (pH value, temperature and light source) on the production of SWE and MWE compounds in correlation with the nitrogen content of the growth medium was studied. SWE compounds were observed in 8 out of 15 soil and aquatic cyanobacterial strains, while MWE compounds were found in all 15 strains. The results show that exposure to UV light induced a higher synthesis of both pigments. Moreover, the presence of SWE compounds was confirmed in cyanobacterial cultures isolated from biological loess crusts (BLCs) as well as in BLC and loess sediment samples. The potential application of these pigment groups as biomarkers in paleoenvironmental and paleoclimatic reconstruction is discussed.

AB  - Surface water, often used for irrigation purposes, may sometimes be contaminated with blooming cyanobacteria and thereby may contain their potent and harmful toxins. Cyanotoxins adversely affect many terrestrial plants, and accumulate in plant tissues that are subsequently ingested by humans. Studies were undertaken to (1) examine the bioaccumulation of microcystins (MCs) in leaves and fruits of pepper Capsicum annuum and (2) examine the potential effects of MCs on antioxidant capacity of these organs. Plants were irrigated with water containing MCs for a period of 3 mo. Data showed that MCs did not accumulate in leaves; however, in fruits the presence of the MC-LR (0.118 ng/mg dry weight) and dmMC-LR (0.077 ng/mg dry weight) was detected. The concentrations of MC-LR in fruit approached the acceptable guideline values and tolerable daily intake for this toxin. Lipid peroxidation levels and flavonoids content were significantly enhanced in both organs of treated plants, while total phenolic concentrations were not markedly variable between control and treated plants. Significant decrease in 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging capacity was noted for both organs. The levels of superoxide anion in fruits and hydroxyl radical in leaves were markedly reduced. Data suggest that exposure to MCs significantly reduced antioxidant capacity of experimental plants, indicating that MCs affected antioxidant systems in C. annuum.
