Alternative tube caps on in vitro growth of Orbignya oleifera Burret.: An Arecaceae native cerrado domain
The babassu (Orbignya oleifera Burret) is a palm that contains oilseeds whose biomass can be used for biofuel production. Due to difficulties in germinating the species, in vitro cultivation techniques are sought as a viable alternative to expand studies on germination. The objective of this study was to evaluate different types of tube caps for in vitro growth of babassu seedlings. Thus, zygotic embryos were inoculated...

On-line methanol sensor system development for recombinant human serum albumin production by Pichia pastoris
An on-line methanol sensor system was developed using a methanol probe, methanol sensor unit and peristaltic pump. The system was commanded using data acquisition (DAQ) and LabVIEW software. Calibration of the methanol sensor system was done in a medium environment with yeast cells during cells adaptation to methanol metabolism after glycerol feeding was stopped. The correlation equations between voltage output signal...

Cloning and expression analysis of alcohol dehydrogenase (Adh) hybrid promoter isolated from Zea mays
Hybrid promoters are created by shuffling of DNA fragments while keeping intact regulatory regions crucial of promoter activity. Two fragments of alcohol dehydrogenase (Adh) promoter from Zea mays were selected to generate hybrid promoter. Sequence analysis of both alcohol dehydrogenase promoter fragments through bioinformatics tools identified several crucial cis regulatory elements and transcription factors binding...

Production and characterization of endoglucanase secreted by Streptomyces capoamus isolated from Caatinga
Cellulases are hydrolases of great importance to industries, especially due to their ability to produce ethanol via hydrolysis of cellulolytic materials. Actinomycetes are the producers of these enzymes, particularly the genus Streptomyces sp. The present study is the first report on the production and characterization of cellulolytic complex secreted by Streptomyces capoamus, isolated from the rhizosphere soil of...
