“…Our data confirm that microorganisms of Lake Baikal can produce biologically active molecules [ 22 ] endowed with a new structure and mechanism of action. Similar studies were carried out in Antarctic lakes, in which significant groups of microorganisms with antimicrobial and antifungal properties were isolated [ 4 , 6 , 21 , 23 , 24 ].…”

“…Seven isolates were isolated from 9 samples of bottom sediments collected in the coastal zone of Lake Baikal (Slyudyanka 51°40′00″ N; 103°42′00″ E; Kultuk 51°41′20″ N; 103°47′00″ E; Listvyanka 51°51′11″ N; 104°52′55″ E; Western end, Figure 1 ) in May–June 2018.The temperature of all bottom sediment samples during sampling was 4.0 ± 0.5°. The samples were collected near the coast at a depth of 2–3 m, only the upper layer of bottom sediments was removed [ 4 , 24 , 26 ]. Selected samples were placed in sterile Petri dishes and frozen at a temperature of −20 °C; after returning to the laboratory, they were stored at −80 °C until further analysis.…”

“…The presence of oxygen at the greatest depths, a feature inherent in oceans but unique among deep lakes (>800 m), explains the presence of multicellular life and the evolution of a vast, primarily endemic fauna down to the deepest parts of the lake. The time for complete water substitution in Lake Baikal is approaching 400 years, which is a considerable period for a lake and resembles oceanic reservoirs [ 4 ].…”

Antimicrobial Potential of Microorganisms Isolated from the Bottom Sediments of Lake Baikal

Extremophilic microorganisms attract researchers by their unique characteristics, primarily antagonistic ones, acquired in the process of survival in extreme natural conditions. The antimicrobial potential of the metabolites of these microorganisms is quite broad, from the food industry to therapeutic drugs. Microbial mats of Lake Baikal are a source of unique and diverse microorganisms. The study aimed to evaluate the antimicrobial activity of bacterial strains isolated from the bottom sediments of the lake. Using heterotrophic growth conditions, seven bacterial strains were isolated from samples collected in several coastal zones of Lake Baikal. Thisstudy identified both widespread strains of the genera Pseudomonas and Bacillus and rare genera Micrococcus and Acinetobacterrepresentatives. Metabolites of five strains were found to have a broad spectrum of antimicrobial activity. Four large fractions of metabolites of the isolated strains wereidentified. Two peptides of the isolated fractions of metabolites (one is produced by microorganisms of all five isolated strains, another—only by Pseudomonas putida) are low molecular weight oligopeptides. These peptides were proved to be bacteriocins.

“…Water body surfaces, both natural and constructed, have been used and transformed to support human activities, including for energy (e.g., oil rigs, hydroelectric power), recreation (e.g., boats), food (e.g., aquaculture), and even housing [106,107]. Offshore oil rigs can have surface areas of upwards of 8600 m 2 [108] and aquaculture farms are commonly greater than 500,000 m 2 in area [109,110].…”

Floating photovoltaic solar energy installations (FPVs) represent a new type of water surface use, potentially sparing land needed for agriculture and conservation. However, standardized metrics for the land sparing and resource use efficiencies of FPVs are absent. These metrics are critical to understanding the environmental and ecological impacts that FPVs may potentially exhibit. Here, we compared techno-hydrological and spatial attributes of four FPVs spanning different climatic regimes. Next, we defined and quantified the land sparing and water surface use efficiency (WSUE) of each FPV. Lastly, we coined and calculated the water surface transformation (WST) using generation data at the world’s first FPV (Far Niente Winery, California). The four FPVs spare 59,555 m2 of land and have a mean land sparing ratio of 2.7:1 m2 compared to ground-mounted PVs. Mean direct and total capacity-based WSUE is 94.5 ± 20.1 SD Wm−2 and 35.2 ± 27.4 SD Wm−2, respectively. Direct and total generation-based WST at Far Niente is 9.3 and 13.4 m2 MWh−1 yr−1, respectively; 2.3 times less area than ground-mounted utility-scale PVs. Our results reveal diverse techno-hydrological and spatial attributes of FPVs, the capacity of FPVs to spare land, and the utility of WSUE and WST metrics.

O zoneamento ambiental é um dos principais instrumentos de planejamento ambiental que contempla a análise integrada dos aspectos naturais e socioeconômicos, o qual permite identificar espacialmente as potencialidades e fragilidades dos sistemas ambientais. Nesse sentido, o presente trabalho teve como objetivo propor um zoneamento hidroambiental da bacia hidrográfica do rio Acará sob um viés sistêmico e integrado da paisagem a partir do conhecimento das suas fragilidades, a fim de identificar as áreas que potencializam a manutenção de água no sistema hidrográfico, com intuito de preservação e conservação dos recursos hídricos. A metodologia baseou-se na proposta de Ross para avaliar a fragilidade dos ambientes antropizados. Para isso, foram utilizados dados geocartográficos dos aspectos do meio físico e o padrão de uso e cobertura da terra com emprego da lógica Fuzzy para confeccionar as cartas de fragilidade hidropotencial e hidroambiental. Os resultados demonstram que o uso e cobertura da terra impactaram diretamente na manutenção de água no sistema hidrográfico da bacia, evidenciado através da conversão de classes com baixa fragilidade hidropotencial para classes com maior nível de fragilidade hidroambiental. Com o diagnóstico das condições hidroambientais da bacia do rio Acará, a proposta de zoneamento hidroambiental apresenta-se como um importante instrumento para os gestores no auxílio do processo de planejamento e reordenamento territorial.
