• Resumen

  • Vibrio species, including Vibrio harveyi, are diverse Gram-negative bacteria common in aquatic ecosystems. Climate change alters ocean conditions like temperature, pH, and salinity, impacting marine life. This study uses Vibrio harveyi to examine how these changes affect bacterial physiology. Higher temperatures increase growth rates but decrease survival, with acidification worsening the impact at moderate temperatures (25°C). Salinity variations at 25°C showed that higher salinities favor growth, while low salinities and low pH reduce culturability. Environmental stressors also cause morphological changes. The study highlights the complex interplay of temperature, pH, and salinity on V. harveyi, underscoring the broader ecological implications of climate change on marine microbes. Understanding these dynamics is crucial for predicting and mitigating climate change impacts on aquatic ecosystems.
