  ABSTRACT
  
  

  To assess the impact of monensin, lasalocid, and a 1:1 (w/w) mixture of monensin and lasalocid on the formation of Microcystis aeruginosa-based harmful algal blooms (HABs), laboratory experiments were conducted [temperature 20 ± 1°C, illumination PAR 30 ± 4 μmol/m2 ·s (12-h light/dark cycle), growth medium BG-11] at concentrations of 100, 200, 500, 1,000, and 2,000 μg/L. Measurements included optical density, cell protein, chlorophyll ‘a’ (Chl. a) content, oxidative stress, catalase activity (CAT), and guaiacol peroxidase activity (GPX). Monensin treatment showed a dose-dependent positive effect on M. aeruginosa growth at concentrations ≤500 μg/L and a gradual dose-dependent growth inhibition at concentrations of 1,000 and 2,000 μg/L. The results indicated that monensin has a significant positive effect on the formation of HABs by M. aeruginosa. Lasalocid treatment showed a growth reduction of M. aeruginosa at concentrations ≤500 μg/L and a growth increase at higher concentrations (1,000 and 2,000 μg/L). The 1:1 (w/w) mixture test showed an intermediate response, as indicated by the individual treatments signifying the potential interactive effects of these antibiotics on M. aeruginosa. Furthermore, alterations in Chl. ‘a’, oxidative stress, CAT, and GPX measurements provided evidence of the impact of these antibiotics on the existence of M. aeruginosa.

  In an era of intense urban development and climate extremes, green infrastructure (GI) has become crucial for creating sustainable, livable, and resilient cities. However, the efficacy of GI is frequently undermined by haphazard implementation and resource misallocation that disregards appropriate spatial scales. This study develops a geographic information system (GIS)-based critical area detection model (CADM) to identify priority areas for the strategic placement of GI, incorporating four main indices—spatial form, green cover, gray cover, and land use change—and utilizing the digital elevation model (DEM), normalized difference vegetation index (NDVI), urban density index (UDI), and up-to-date land use data. By employing the developed method, the study successfully locates priority zones for GI implementation in Saitama City, Japan, effectively pinpointing areas that require immediate attention. This approach not only guarantees efficient resource allocation and maximizes the multifunctional benefits of GI but also highlights the importance of a flexible, all-encompassing GI network to address urbanization and environmental challenges. The findings offer policymakers a powerful tool with which to optimize GI placement, enhancing urban resilience and supporting sustainable development.

• Flow velocity and light intensity combination is important for Microcystis aeruginosa physical suppression

  Abstract
  
  The cyanobacterial response to flow velocity or light intensity deviates from the combined effect of both factors. The responses of Microcystis aeruginosa to different combinations of flow velocities and light intensities were tested. Growth (OD₇₃₀ and protein), stress (catalase, ascorbate peroxidase, and glutathione peroxidase), and photosynthetic ability (chlorophyll‐a and fluorescence) parameters of M. aeruginosa were measured to evaluate the effects of different combinations. Exposure to different flow velocity–light combinations significantly affected the growth and physiology of M. aeruginosa. Flow velocities of 0.4 m s⁻¹ showed a prominent influence on most of the measured parameters compared with no flow velocity or higher flow velocity conditions. The 1.2‐m s⁻¹ flow velocity and high light intensity (1200 μmol m⁻² s⁻¹) exposure caused a significant elevation in oxidative stress. Lower velocities are beneficial for M. aeruginosa at light stress, whereas extreme velocities are adverse and elevate the stress. Two categories of light–velocity combinations were identified as preferred and extreme categories, depending on whether they suppressed or supported M. aeruginosa growth. In controlling cyanobacteria blooms using flow or high‐intensity light, it is imperative to consider the interaction of these two factors, as their combined effects can significantly vary the stress levels in cyanobacteria. A new system, designed to minimize mechanical damage on M. aeruginosa, was used to generate flow velocities. Additionally, the combined effects of flow velocities and light intensities have been considered for the first time.
  
  Practitioner Points
  
  Flow velocity can influence the effect of light on Microcystis aeruginosa.
  
  High light exposure effect on Microcystis aeruginosa can be reduced by low flow velocity.
  
  High flow velocity and high light exposure increase the stress on Microcystis aeruginosa.
  
  Different light intensities and flow velocity combinations changed Microcystis aeruginosa stress physiology.

• Egeria densa organic extracts: an eco-friendly approach to suppress Microcystis aeruginosa growth through allelopathy

  Abstract
  
  

  Macrophytes play a significant role in shaping plankton communities by shading, controlling water turbulence, and nutrient availability, while also producing allelochemicals causing varying effects on different organisms. Many researchers have shown that when live macrophytes are present, they inhibit cyanobacteria. However, their widespread use is often limited due to numerous concerns, including invasive characteristics. This study focused on the applicability of Egeria densa extracts to suppress Microcystis aeruginosa. We employed pure water and dimethyl sulfoxide, to obtain compounds from E. densa. The results revealed that E. densa aqueous extracts stimulated M. aeruginosa growth, whereas organic extracts exhibited suppression. Specifically, at low concentrations of organics extracts (0.5 and 1 g/L), after day 4, the growth inhibition was confirmed by significantly higher (p < 0.05) stress levels shown in cells treated with low concentrations. The highest inhibition rate of 32% was observed at 0.5 g/L. However, high concentrations of organic extracts (3 and 6 g/L), showed increased growth compared with control. These results suggest that high concentrations of organic extracts from E. densa potentially suppress allelochemical-induced M. aeruginosa inhibition due to high nutrient availability. In comparison with an aqueous solvent, the use of organic solvent seems to be more effective in efficiently extracting allelochemicals from E. densa.

  Cyanobacteria growth can be suppressed using extreme light exposure for a shorter duration. Due to the extreme light, their physiology and growth behaviors were altered. Oxidative stress of P. ambiguum and M. aeruginosa increased with the light intensity. The responses were species-specific. Under long-duration extreme light (850 - 900 PAR), M. aeruginosa cells were adapted to stress. When the stress is removed, cells recovered rapidly. Darkness exposure (30 d) completely discolored M. aeruginosa and P. galeata, but were recovered aggressively. It is understood that extreme light alone cannot continously suppress cyanobacterial growth. The Egeria densa allelopathy combined with light conditions can effectively suppress the M. aeruginosa. The outcome of this research is that cyanobacteria can be suppressed by combining high light exposure and allelopathy.
