Two proteolytic thermophilic aerobic bacterial strains, PA-9 and PA-5, were isolated from Buranga hot springs in western Uganda. The cells were rods, approximately 10–12 μm in length and 3 μm in width. Isolate PA-9 grew at between 38°C and 68°C (optimum, 62°C), and PA-5 grew at between 37°C and 72°C (optimum, 60°C). Both isolates grew optimally at pH(More)
A 4-hydroxyphenylacetic acid (4-HPA) hydroxylase-encoding gene, on a 2.7-kb genomic DNA fragment, was cloned from the thermophile Geobacillus sp. PA-9. The Geobacillus sp. PA-9 4-HPA hydroxylase gene, designated hpaH, encodes a protein of 494 amino acids with a predicted molecular mass of 56.269 Da. The deduced amino-acid sequence of the hpaH gene product(More)
BACKGROUND Uganda's banana industry is heavily impeded by the lack of cheap, reliable and sustainable energy mainly needed for processing of banana fruit into pulp and subsequent drying into chips before milling into banana flour that has several uses in the bakery industry, among others. Uganda has one of the lowest electricity access levels, estimated at(More)
