Abstract The Winam Gulf (Kenya) is frequently impaired by cyanobacterial harmful algal blooms (cHABs) due to inadequate wastewater treatment and excess agricultural nutrient input. While phytoplankton in Lake Victoria have been characterized using morphological criteria, our aim identify potential toxin‐producing cyanobacteria molecular approaches. was sampled over two successive summer seasons, 16S 18S ribosomal RNA gene sequencing performed. Additionally, key genes involved production of...
ABSTRACT The Winam Gulf in the Kenyan region of Lake Victoria experiences prolific, year-round cyanobacterial harmful algal blooms (cyanoHABs) which pose threats to human, livestock, and ecosystem health. To our knowledge, there is limited molecular research on gulf’s cyanoHABs, thus, strategies employed for survival proliferation by toxigenic cyanobacteria this remain largely unexplored. Here, we used metagenomics analyze Gulf’s composition, function, biosynthetic potential. Dolichospermum...
The Nile perch (Lates niloticus L.) commercial fishery for Lake Victoria in East Africa is an important source of revenue and employment. We focused on shifts food web structure total mercury (THg) bioaccumulation biomagnification perch, lower items collected from Winam Gulf (Kenya) sampled 24 years apart (1998 2022). Stable isotope carbon (δ13C) values were higher all species 2022 compared to 1998. nitrogen (δ15N) baseline organisms In δ15N correlated with length, but the δ15N-length...
Sandusky Bay is the drowned mouth of River in southwestern portion Lake Erie. The bay a popular recreation location and regional source for drinking water. Like western basin Erie, known being host to summer cyanobacterial harmful algal blooms (cHABs) year after year, fueled by runoff from predominantly agricultural watershed internal loading legacy nutrients (primarily phosphorus). Since at least 2003, has harbored microcystin-producing bloom Planktothrix agardhii, species filamentous...
We report 40 metagenomic libraries collected from the Winam Gulf of Lake Victoria during May-July 2022-2023 and an additional eight opportunistic adjacent Lakes Simbi, Naivasha, regional river systems. The sampling period captured cyanobacterial bloom events - shedding insight onto community composition genomic potential.
Microcystin-producing cyanobacterial blooms are a global issue threatening drinking water supplies and recreation on lakes beaches. Direct measurement of microcystins is the only way to ensure waters have concentrations below guideline concentrations; however, analyzing for takes several hours days obtain data. We tested LightDeck Diagnostics’ bead beater cell lysis two versions quantification system designed give microcystin within 20 minutes compared it standard freeze-thaw cycle method...
