AB  - Raw jute fabric was treated with 0.5, 1.0, or 2.0% chitosan solution to improve its sorption
properties (evaluated through the moisture sorption and adsorption of textile dye Reactive Orange 16 (RO 16)), which are essential for fabric utilization as geo-prebiotic polysaccharide support that should provide the necessary water for the growth of cyanobacterial communities in biocarpet engineering. Chitosan-treated fabrics possessed 39–78% higher moisture sorption values than the untreated ones. Concerning the dye adsorption, with the increase in its initial concentration, the adsorption potential of raw and fabrics treated with 0.5 or 1.0% chitosan solution was increased up to 1.9 times. The dye adsorption onto these fabrics was exothermic and enthalpy driven. By increasing the chitosan solution percentage up to 1.0%, fabric adsorption potential increased up to 2.2 times. An inverse relationship was observed in the case of the fabric treated with 2.0% chitosan solution, its adsorption potential decreased with increasing the initial dye concentration and temperature due to the different dominant binding interactions. Concerning the contact time, dye adsorption onto fabric treated with 1.0% chitosan solution was rapid in the first 2 h, while the equilibrium was attained after 4.5 h. The isotherm and kinetic data were represented by the Langmuir model and the pseudo-second-order kinetic model, respectively.

AB  - Over 40% of terrestrial ecosystems worldwide suffer from land degradation, a natural or human-influenced process that affects the functionality of the land. Cyanobacterial biocrust carpet engineering has been proposed to fight land degradation. However, the rehabilitation takes a long time due to the lack of moisture during the initial phase. To solve this problem, our new project Integrated Strategy for Rehabilitation of Disturbed Land Surfaces and Control of Air Pollution (RECAP) will introduce different types of polysaccharide supports with improved sorption properties. Such supports will increase the availability of water as the main limiting factor. The viability of the cyanobacterial inoculum will be improved, the development of the biocrust accelerated and finally the efficiency of the biocrust carpet significantly increased. 
The theoretical background for RECAP novelty is based on two scientific concepts developed by the RECAP team: the BLOCDUST hypothesis and the SYNERGOSIS concept. The BLOCDUST hypothesis describes the role of cyanobacteria in the process of loessification. A new definition of loess emerged from it: loess is not eolian sediment only but also biogenic. The dual origin of loess and some other sediments has been described under concept of synergosis, a new term we introduced into sciences emphasizing the physical and functional relation between biotic and abiotic components where both benefit from each other.
Analyses of cyanobacterial biomass, polysaccharide and cyanotoxin production were performed. The presence of toxin genes in the selected strains was also checked and found to be negative in order to guarantee environmental and human safety.

AB  - In the present review we have discussed the occurrence of β-N-methylamino-L-alanine (BMAA) and its natural isomers, and the organisms and sample types in which the toxin(s) have been detected. Further, the review discusses general pathogenic mechanisms of neurodegenerative diseases, and how modes of action of BMAA fit in those mechanisms. The biogeography of BMAA occurrence presented here contributes to the planning of epidemiological research based on the geographical distribution of BMAA and human exposure. Analysis of BMAA mechanisms in relation to pathogenic processes of neurodegeneration is used to critically assess the potential significance of the amino acid as well as to identify gaps in our understanding. Taken together, these two approaches provide the basis for the discussion on the potential role of BMAA as a secondary factor in neurodegenerative diseases, the rationale for further research and possible directions the research can take, which are outlined in the conclusions.

AB  - This chapter presents a case study of a toxic Planktothrix rubescens bloom in the Serbian reservoir Vrutci used as the water supply for the city of Užice. Chemical cyanotoxin analyses were supplemented by Artemia salina bioassays, a questionnaire directed to the inhabitants of Užice, and epidemiological work. The overall aim of the studies was to assess the potential human health impacts of the toxic bloom.
