Cyanobacterial diversity in the hot spring, pelagic and benthic habitats of a tropical soda lake
Dadheech, Pawan K.; Glockner, G.; Casper, P.; Kotut, Kiplagat; Mazzoni, C.J.; Mbedi, S.; Krienitz, L. (2013-08)Hot springs and saline-alkaline lakes of East Africa are extreme habitats regarding temperature, or salinity and pH, respectively. This study examines whether divergent habitats of Lake Bogoria, Kenya, impacts cyanobacterial ... -
Desertifilum fontinale sp. nov. (Oscillatoriales, Cyanobacteria) from a warm spring in East Africa, based on conventional and molecular studies
Dadheech, Pawan K.; Mahmoud, Huda; Kotut, Kiplagat; Krienitz, L. (2014)Desertifilum is a filamentous cyanobacterium of crusts and biofilms, recently described from the extreme hot and dry Thar Desert in north–western India. A new species was isolated from a warm spring near Lake Bogoria, Kenya ... -
Food algae for Lesser Flamingos: a stocktaking
Krienitz, Lothar; Krienitz, Doris; Dadheech, Pawan K.; Hübener, Thomas; Kotut, Kiplagat; Luo, Wei; Teubner, Katrin; Versfeld, Wilferd D. (Springer, 2016-07)Lesser Flamingo, the flagship species of saline wetlands of Africa and India, is a specialised feeder subsisting on microscopic cyanobacteria and algae. To establish the relationship between flamingo occurrence and food ... -
Haloleptolyngbya alcalis gen. et sp. nov., a new filamentous cyanobacterium from the soda lake Nakuru, Kenya
Dadheech, Pawan K.; Mahmoud, Huda; Kotut, Kiplagat; Krienitz, L. (Springer, 2012)The food web of the saline-alkaline Lake Nakuru is dominated by the cyanobacterium Arthrospira fusiformis as the primary producer and a huge population of Lesser Flamingos as direct consumers. However, the dense blooms ... -
Mass developments of a small sized ecotype of Arthrospira fusiformis in Lake Oloidien, Kenya, a new feeding ground for Lesser Flamingos in East Africa
Krienitz, L.; Dadheech, Pawan K.; Kotut, Kiplagat (2013)The Lesser Flamingos constantly commute between the soda lakes of East Africa in search of food. Their preferred food, the cyanobacterium Arthrospira fusiformis, usually establishes dense populations in saline–alkaline ... -
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. ... -
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 ... -
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 ...
