Odenyo, A.A.JunSang, H.Osuji, P.O.[Isolation and evaluation of bacteria from indigenous African animals for evidence of superior cellulolytic enzymes (Challenges for Microbial Digestive Ecology)]Isolation and evaluation of bacteria from indigenous African animals for evidence of superior cellulolytic enzymes (Challenges for Microbial Digestive Ecology)

Several tannin-tolerant bacteria were isolated from enrichment cultures of rumen microflora of bush duiker, giraffe, Grant's gazelle, sheep, and goat, and established in medium containing crude tannin extracts or tannic acid. The isolates were characterized by classical and molecular methods. The...


Odenyo, A.A.Bishop, Richard P.Asefa, G.Jamnadass, Ramni H.Odongo, D.Osuji, P.O.[Characterization of tannin-tolerant bacterial isolates from East African ruminants]Characterization of tannin-tolerant bacterial isolates from East African ruminants

The effect of Acacia angustissima on rumen fermentation was evaluated. Acacia angustissima was fed to two groups of cannulated Ethiopian highland sheeOne group (three animals) was directly supplemented with 300 g per head day-1 of sun-dried A. angustissima. These animals died after 9 and 21 days ...


Odenyo, A.A.Osuji, P.O.Karanfil, O.Adinew, K.[Microbiological evaluation of Acacia angustissima as a protein supplement for sheep]Microbiological evaluation of Acacia angustissima as a protein supplement for sheep

Two strains of obligately anaerobic cellulolytic bacteria designated as PS7 and PS8 (PS for porcupine species) were isolated from hindgut fluid of a crested porcupine (Hystrix cristata). The rates of cellulose degradation, total volatile fatty acids, and gas production from cellulose by the isola...


Odenyo, A.A.Bishop, Richard P.Asefa, G.Wells, C.Osuji, P.O.[Isolation and characterization of anaerobic cellulose-degrading bacteria from East African porcupine (Hysterix cristata)]Isolation and characterization of anaerobic cellulose-degrading bacteria from East African porcupine (Hysterix cristata)

Supplementation of basal diets with multipurpose trees (MPTs) increases essential nutrients available to rumen microbes, increases rate of passage of particulate matter by 23-53 percent and of liquid matter by 9-43 percent. Supplementing teff straw with graded levels of cowpea or lablab significa...


Osuji, P.O.Odenyo, A.A.[The role of legume forages as supplements to low quality roughages - ILRI experience]The role of legume forages as supplements to low quality roughages - ILRI experience

Four straight rods and three spherical bacteria were isolated using roll tubes inoculated with rumen fluid from sheep and goats and enriched with tannic acid. The isolates were characterized by morphology, products of fermentation and restriction fragment length polymorphism that indicated the co...


Kebede, M.Odenyo, A.A.Assefa, F.[Isolation and characterization of tannins tolerant bacteria from rumen fluid of free ranging sheep and goats]Isolation and characterization of tannins tolerant bacteria from rumen fluid of free ranging sheep and goats

Three strains of tannin-tolerant rumen bacteria were isolated from enrichment cultures of rumen microflora of sheep, goat, and antelope and established in medium containing high concentrations of crude tannin extract or tannic acid. These three strains (EAT2, ES3, and EG19), characterized as Sele...


Odenyo, A.A.Osuji, P.O.[Tannin-tolerant ruminal bacteria from East African ruminants]Tannin-tolerant ruminal bacteria from East African ruminants

The aim of this study was to isolate and characterize bacteria capable of hydrolysing tannins from the faeces of Ethiopian ruminants adapted to feed on tannin-rich leaves. Faecal samples were collected from dikdik (Madoqua guentheri), camel (Camelus dromedaries), Grant's gazelle (Gazella granti),...
