1. Fermentação, purificação, caracterização bioquímica e microencapsulação da protease produzida pelo fungo Eupenicillium javanicum / Fermentation, purification, biochemical characterization, and microencapsulation of protease produced by the fungus Eupenicillium javanicum
Foram analisados alguns parâmetros que influenciam os bioprocessos, submerso e sólido, do fungo Eupenicillium javanicum na produção de peptidases. No bioprocesso submerso foram avaliados a influência de diferentes concentrações e tipos de fonte de carbono e concentrações de fonte nitrogênio no meio, pH, temperatura e tempo de incubação. No biopro

2. Aplicações de nanoeletrodos como sensores na Química Analítica
Nanomaterials make up an emerging area in Chemistry and in the science of materials. This area constitutes the development of methods for synthesizing nanoscopic particles of a given material used for scientific investigation. Nanomaterials have a wide range of commercial possibilities and technological applications, including their use in analytical chemist

3. Bioencapsulation of Two Different Vibrio Species in Nauplii of the Brine Shrimp (Artemia franciscana)
Two groups of nauplii from the brine shrimp (Artemia franciscana) were enriched with different bacteria, and the dynamics of bacterial uptake by the nauplii were observed. This study showed that the efficiency of Artemia nauplii in bioencapsulating bacteria strongly depends on the type of bacteria used, time of exposure, and status (live or dead) of the bact

4. Germination, Growth, and Sporulation of Bacillus thuringiensis subsp. israelensis in Excreted Food Vacuoles of the Protozoan Tetrahymena pyriformis
Spores of Bacillus thuringiensis subsp. israelensis and their toxic crystals are bioencapsulated in the protozoan Tetrahymena pyriformis, in which the toxin remains stable. Each T. pyriformis cell concentrates the spores and crystals in its food vacuoles, thus delivering them to mosquito larvae, which rapidly die. Vacuoles containing undigested material are

5. Oral immunization with hepatitis B surface antigen expressed in transgenic plants
Oral immunogenicity of recombinant hepatitis B surface antigen (HBsAg) derived from yeast (purified product) or in transgenic potatoes (uncooked unprocessed sample) was compared. An oral adjuvant, cholera toxin, was used to increase immune responses. Transgenic plant material containing HBsAg was the superior means of both inducing a primary immune resp

6. Accumulation of trimethoprim, sulfamethoxazole, and N-acetylsulfamethoxazole in fish and shrimp fed medicated Artemia franciscana.
In a previous paper (H.J. Nelis, P. Léger, P. Sorgeloos, and A. P. De Leenheer, Antimicrob. Agents Chemother. 35:2486-2489, 1991) it was reported that two selected antibacterial agents, i.e., trimethoprim and sulfamethoxazole, can be efficiently bioencapsulated in nauplii of the brine shrimp Artemia franciscana for administration to fish.
