1. Isolation, characterization and fermentative activity of mango pulp spoilage bacteria / Isolamento, caracterização e atividade fermentativa de bactérias deterioradoras de polpa de manga
The mango (Mangifera indica Linn.) is one of the most important tropical fruits. It is very appreciated due to its flavor and nutritional characteristics. The fruits are easily spoiled because of intrinsic factors, which makes difficult its commercialization in natura. An alternative to reduce the losts is the conservation of the mango as pulp, juice and nec

2. The Bacillus subtilis Signaling Protein SpoIVB Defines a New Family of Serine Peptidases
The protein SpoIVB plays a key role in signaling in the ςK checkpoint of Bacillus subtilis. This regulatory mechanism coordinates late gene expression during development in this organism and we have recently shown SpoIVB to be a serine peptidase. SpoIVB signals by transiting a membrane, undergoing self-cleavage, and then by an unknown mechanism activating a

3. Determination of Escherichia coli Contamination with Chromocult Coliform Agar Showed a High Level of Discrimination Efficiency for Differing Fecal Pollution Levels in Tropical Waters of Kampala, Uganda
Escherichia coli, total coliforms, fecal coliforms, and sulfite-reducing anaerobic spore formers from different polluted sites in a tropical environment were determined in order to test for their indication ability for fecal contamination. Quantification of E. coli contamination with Chromocult coliform agar proved to be efficient and feasible for determinin

4. Microbiological Evaluation of Incinerator Operations1
Incineration is currently a widely used method for the disposal of municipal solid waste in major American cities. The efficacy of several incinerator types to destroy bacteria associated with solid waste was evaluated, with emphasis on fecal and food sources. Samples of solid waste and its residue after incineration, taken from four incinerators of differen

5. Gamma processing of Arabic bread for immune system-compromised cancer patients.
Arabic bread prepared from local Saudi flour contained a total of up to 10(4) organisms per g. Most of these were bacterial spores that survived the baking process (1.3 X 10(2) to 3.5 X 10(3] and a small number of yeasts and molds (10 to 40 cells per g). The organisms in Arabic bread appear to be harmless to healthy individuals. However, for immune system-co

6. Cocoa Fermentations Conducted with a Defined Microbial Cocktail Inoculum
Cocoa fermentations were performed in wooden boxes under the following four experimental regimens: beans naturally fermented with wild microflora; aseptically prepared beans with no inoculum; and beans inoculated with a defined cocktail containing microorganisms at a suitable concentration either at zero time or by using phased additions at appropriate times
