The lake is situated on the floor of the Kenyan Rift Valley at 1,776 m above sea level and has no direct outlet. The microbial diversity ... -
Characterization of various Bacillus thuringiensis strains having larvicidal activity on Chilo partellus first-instar larvae, after culture on cost-effective medium, in Kenya
Anyika, D.; Boga, Hamadi I.; Mwirichia, Romano K. (2011)Bacillus thuringiensis strains are widely used in many larvicidal pest control programs. However, the large-scale production of these biolarvicides is very expensive due to the high cost of the production synthetic medium. ... -
Development of cost-effective media for the culture of Chilo partellus larvicide in Kenya
Anyika, D.; Boga, Hamadi I.; Mwirichia, Romano K. (Academic Journals, 2013-03)Stem borers (Chilo partellus) are important field insect pests of maize (Zea mays L.) and sorghum (Sorghum bicolor L.) in Africa. They account for more than 30% yield losses depending on the composition of the pest community. ... -
Diversity of Termitomyces Associated with Fungus- Farming Termites Assessed by Cultural and Culture- Independent Methods
Makonde, H.M.; Boga, Hamadi I.; Osiemo, Z.; Mwirichia, Romano K.; Stielow, J.B.; Go¨ ker, Markus; et al. (2013)Background: Fungus-cultivating termites make use of an obligate mutualism with fungi from the genus Termitomyces, which are acquired through either vertical transmission via reproductive alates or horizontally transmitted ... -
Evaluation of prokaryotic diversity of five hot springs in Eritrea
Ghilamicael, Amanuel M.; Budambula, Nancy; Anami, Sylvester E.; Mehari, Tadesse; Boga, Hamadi I. (BioMed Central, 2017-09)Background: Total community rDNA was used to determine the diversity of bacteria and archaea from water, wet sediment and microbial mats samples of hot springs in the Eastern lowlands of Eritrea. The temperatures of ... -
Isolation and characterisation of bacteria from the haloalkaline Lake Elmenteita, Kenya
Mwirichia, Romano K.; Muigai, A.W.; Tindall, B.; Boga, Hamadi I.; Stackebrandt, E. (Springer, 2010-04)Culture-independent studies show that soda lake environments harbour diverse groups of bacteria and archaea. In this study different enrichment and isolation media were used in an attempt to isolate novel groups of bacteria ... -
