Isolation And Propagation Of Lactic Acid Bacteria From Fermented Maize Flour For The Optimization Of The Fermentation Process
(UoN, 2019)Production of traditional fermented foods especially lactic acid fermented foods has long been practiced for ages in Africa with a variety of products being produced. Lactic fermentation improves the digestibility of ... -
Isolation And Screening For Antibiotics From Soil Actinomycetes And Their Control Of Fusarium Wilt Of Carnation Caused By Fusarium Oxysporum Schi. F. Sp. Dianthi (prill. & Del.) Snyder And Hansen
(University of Nairobi.Department of Plant Science and Crop Protection, 1992)Twenty three actjnomycete isolates were isolated r from soiI samples collected from a cow shed, pasture land, and culttivated land. The cow shed soils were shown to have a higher population of actinomycetes than e1ther ... -
Isolation and Screening of Actinomycetes From Volcanic Soils of Menengai Crater in Kenya for Antibiotic Activity Using Culture and Genomic Techniques
(University of Nairobi, 2019)Diseases are the most dangerous enemy of man despite the many strides made in medicine today. The growing list of antibiotic resistant human pathogens in recent years has made the search for new, safe antibiotics a top ... -
Isolation and sequence analysis of a plasmodium Falciparum gene encoding glucosamine fructose -6- Phosphate aminotransferase from parasite line Nf54
(Department of biochemistry University of Nairobi, 2006)The purpose of this study was to Isolate and analyse the DNA and amino acid sequence of the enzyme glucosamine fructose-6- phosphate aminotransferase (GFAT) fromPlasmodium falciparum parasite line NF54. GFAT is the rate ... -
Isolation of Avian Paramyxoviruses from village chickens and wild birds in Kenya
(Department of Veterinary Pathology, Microbiology and Parasitology, University of Nairobi, 2000)The potential of village chickens in Kenya has not been fully exploited because most farmers do not practice disease control, supplementation, and there is no proper housing for the birds. Control of viral diseases ... -
Isolation of functional phage displayed single domain antibody fragments against dichloro-diphenyl-trichloroethane (DDT),chloroquine and plasmodial thiazole kinase.
(2004)The target of molecular engineers has been to generate smaller antibody fragments from the large complete antibodies that still retain the antigen binding activity. Small fragments equipped with radioisotopes can be used ... -

Isolation of soil actinomycetes from different sites and screening for their antimicrobial activity
(Schoolof Biological Sciences College of Biological and Physical Sciences University of Nairobi, 2008)Screening of several microbes for bioactive compounds is an open avenue for discovery of novel bioactive compounds with varied functions as agricultural chemicals. The work done resulted in isolation of seventeen ... -
Isolation of soil actinomycetes, characterization and screening of their antibiotics against economically important plant pathogens
(University of NairobiDepartment of Crop Science, 2000)Forty one actinomycete isolates were isolated from soils collected in three different sites namely cultivated land, pasture land and cattle shed. The cattle shed had the highest number of actinomycetes with 19 followed ... -
Isolation, characterisation and pathogenicity testing of escherichia coli occurring in poultry in some parts of Kenya
(University of NairobiDepartment of veterinary pathology and microbiology,, 1997)Poultry is a good source of protein (eggs and meat) because they are fast growmg. Their productivity however is affected by, among other things, bacterial infections among which is Escherichia coli. Escherichia coli is ... -
Isolation, characterization and evaluation of potency of native bacillus thuringiensis against maize insect pests and aflatoxin producing fungi
(University of NairobiSchool of Biological Sciences, 2010)Bio-control of pests using Bacillus thuringiensis represents the most potential use of biological control agents to date. Among major constraints to maize production, safety and hence food sufficiency in Kenya is ... -
