Mass developments of the cyanobacteria Anabaenopsis and Cyanospira (Nostocales) in the soda lakes of Kenya: ecological and systematic implications
Krienitz, L.; Dadheech, Pawan K.; Kotut, Kiplagat (2013)The food web of the saline–alkaline lakes of East Africa is characterised by a unique interaction between the Lesser Flamingos as consumer birds and the cyanobacterium Arthrospira fusiformis as the primary producer. ... -
Molecular detection of uncultured cyanobacteria and aminotransferase domains for cyanotoxin production in sediments of different Kenyan lakes
Dadheech, Pawan K.; Krienitz, L.; Kotut, Kiplagat; Ballot, A.; Casper, P. (Blackwell Publishing Ltd, 2009-04-15)PCR-based denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA gene fragments was used to identify the cyanobacterial phylotypes in sediments and plankton of saline–alkaline and freshwater lakes of Kenya. ... -
Molecular diversity of plankton in a tropical crater lake switching from hyposaline to subsaline conditions: Lake Oloidien, Kenya
Kotut, Kiplagat; Luo, Wei; Li, Huirong; Krienitz, Lothar (Springer, 2016-09)Salinity in the climate sensitive tropical endorheic crater lake Oloidien (Great African Rift Valley, Kenya) decreased from hyposaline to subsaline conditions during the period 2010–2015. The change in salinity was ... -
Phylogenetic relationship and divergence among planktonic strains of Arthrospira (Oscillatoriales, Cyanobacteria) of African, Asian and American origin deduced by 16S–23S ITS and phycocyanin operon sequences
Dadheech, Pawan K.; Ballot, A.; Casper, P.; Kotut, Kiplagat; Novelo, E.; Lemma, B.; Proschold, T.; Krienitz, L. (2010-07)Arthrospira comprises multicellular, cylindrical, usually screwlike coiled trichomes and is cultivated commercially. In this study, 33 new strains of Arthrospira isolated from plankton samples collected in Mexico, East ... -
Physico-Chemical and Microbial Quality of Greywater from Various Households in Homa Bay Town
Kotut, Kiplagat; Nganga, V.G.; Kariuki, F.W. (2011)In recent years concerns over dwindling reserves of ground water and overloaded or costly sewage treatment plants has generated much interest in the reuse or recycling of greywater. Re-use of greywater offers several ... -
The Physico-chemical Conditions of Turkwel Gorge Reservoir, a New Man Made Lake in Northern Kenya
Kotut, Kiplagat; Njuguna, Stephen; Muthuri, Francis M.; Krienitz, L. (1999)Variations in some physical, chemical, and nutrient conditions were investigated at Turkwel Gorge Reservoir and its inflowing river, Suam between 1994 and 1995. Seasonal changes in inflow volume had the greatest impact ... -
Picocystis salinarum (Chlorophyta) in saline lakes and hot springs of East Africa.
Krienitz, L.; Bock, Christina; Kotut, Kiplagat; Luo, Wei (2012-01)The occurrence of Picocystis salinarum in saline inland waters of East Africa was investigated using a polyphasic approach of small-subunit (SSU) rDNA phylogeny and light microscope observations. Recent studies have found ... -
The Potential of a Low Cost Technology for The Greywater Treatment
Kariuki, F.W.; Kotut, Kiplagat; Ngángá, V.G. (2011)Greywater (GW) is household wastewater effluent originating from baths, showers, kitchen and hand wash basins and laundry and constitutes 50-80% of indoor household water use. It represents water that can potentially be ... -
The rise of potentially toxin producing cyanobacteria in Lake Naivasha, Great African Rift Valley, Kenya
Krienitz, L.; Dadheech, Pawan K.; Jutta, Fastner; Kotut, Kiplagat (Elsevier, 2013-07)Lake Naivasha, an important inland water ecosystem and a crucial freshwater resource in the Great African Rift Valley, has displayed clear signals of degradation in recent decades. We studied the phytoplankton composition ... -
Temporal changes in phytoplankton structure and composition at the Turkwel Gorge Reservoir, Kenya
Kotut, Kiplagat; Krienitz, L.; Muthuri, Francis M. (Kluwer Academic Publishers, 1998)Temporal changes in phytoplankton chlorophyll a, composition, diversity, biomass (density and fresh weight) and primary production were investigated at the Turkwel Gorge Reservoir (Kenya) over a two year period (1994 and ... -
Toxic cyanobacteria and their toxins in standing waters of Kenya: implications for water resource use
Kotut, Kiplagat; Ballot, A.; Krienitz, L. (2006-06)Phytoplankton biodiversity studies in Kenya's standing waters were carried out between 2001 and 2003. Toxin producing cyanobacteria were recorded in twelve water bodies. Microcystis and Anabaena were the most common species ...
