Twelve strains of methanot-assimi}ating yeast species were examined for their partial base sequences of 18S and 26S rRNAs. In the partial base sequencings of 18S rRNA (positions 1451-1618, 168 bases), P. kodomae had the same partial base sequence as Qgataea minuta, and P. finlandica, P. pini, P. trehatophila, CL maris, and CL methanolovescens were the same in the partial base sequences as O. gl...

Crude extracts from Warburgia ugandensis Sprague, Azadirachta indica, Tagetes minuta and Urtica massaica have been tested against soil pathogens; Fusarium oxysporum, Alternaria passiflorae and Aspergillus niger. The results obtained showed biological activity against these pathogens except for U. massaica extract, which was not active. Separation of the crude extract from W. ugandensis yielded ...

Background and Aims: Although local plants as mosquito repellents are known and used among the different cultures of Africa and beyond, little effort is done to document about the knowledge, usage pattern and their repellency potential in Ethiopia in general and specifically around Gilgelgibe Field Research Centre, Jimma Zone, Southwest Ethiopia. This study was aimed to assess the ethno botanic...

Species of Tagetes, which belong to the family Asteraceae show different characteristics including, bloom size, shape, and color; plant size; and leaf shape. In this study, we determined the differences in primary metabolites and carotenoid yields among six cultivars from two Tagetes species, T. erecta and T. patula. In total, we detected seven carotenoids in the examined cultivars: violaxanthi...
