“…In assessing the effect of pH, cells were incubated in BG-11 medium adjusted to different pH levels (4-12) using universal buffers. Following a 72-hour incubation period under continuous light exposure, hydrogen production was monitored every 24 hours to evaluate the impact of pH on H₂ generation [7]. To explore the effect of temperature, the experiment involved incubating the cells at a range of temperatures from 20°C to 35°C.…”

The escalating environmental challenges precipitated by the uncontrolled use of fossil fuels, notably the rise in global average temperatures, underscore the urgent need for sustainable energy solutions. This context has heightened the significance of exploring renewable energy sources, particularly through the lens of biological research aimed at uncovering viable alternatives to conventional energy forms. Against this backdrop, our study embarked on the isolation and characterization of the cyanobacterium Synechocystis sp. strain PSU 1262, sourced from the Badam River in the Turkestan region, employing 16S rRNA sequencing for its identification. The primary objective of our research was to assess the hydrogen-producing potential of PSU 1262 under a variety of environmental conditions. Our findings reveal that this strain achieves peak hydrogen production in slightly alkaline conditions and exhibits a marked decline in productivity when subjected to elevated sodium nitrate levels. Furthermore, we determined that PSU 1262 optimally generates hydrogen within a specific temperature range (27-30°C) and under certain light intensity conditions. These insights are pivotal, indicating that precise environmental management is essential for maximizing the biohydrogen output of this strain. The study conclusively highlights the capability of PSU 1262 as a promising agent for biohydrogen production, offering a significant contribution to the field of renewable energy and presenting a sustainable alternative to mitigate the environmental impact of traditional energy sources.

“…These cells employ semiconductor materials to capture sunlight and initiate water splitting, thereby generating electrons. These electrons then drive chemical reactions that synthesise valuable fuels or chemicals (Najafpour et al 2015(Najafpour et al , 2022Kamshybayeva et al 2023). The overarching aim is to produce a clean, renewable energy source, while also addressing climate change by converting CO2 into value-added products.…”
