Plant latex lipase as biocatalysts for biodiesel production
Industrial-scale processes currently developed make use of chemical catalysis processes that are highly efficient but require very complex product puriï¬cation steps. Enzymatic catalysis through plant lipases as biocatalysts is an alternative which, in contrast to chemical catalysis processes, appeared simple to perform, and can be done at low investment cost. Although microbial lipases have been extensively studied,...

Micropropagation of Guadua angustifolia Kunth (Poaceae) using a temporary immersion system RITA®
The micropropagation of Guadua angustifolia Kunth, commonly known as giant bamboo, using semi-solid culture medium, is reported to have low multiplication rates. This study evaluated the multiplication index of G. angustifolia in a temporary immersion system (RITA®), comparing results with those obtained using a semi-solid culture medium. The treatments consisted of either three or four 2-min immersions per day and...

Characterization of α-amylase produced by the endophytic strain of Penicillium digitatum in solid state fermentation (SSF) and submerged fermentation (SMF)
α-Amylases are enzymes responsible for breaking the α-1,4 bond in polysaccharides with three or more glucose units, occupying the second place in the most widely employed enzymes in industry in the world. The objective of this study was to compare the yields of α-amylase produced by the endophytic fungus, Penicillium digitatum, strain D1-FB, isolated from Baccharis dracunculifolia D.C. (Asteraceae),...

Development of bio-hybrid material based on Salmonella Typhimurium and layered double hydroxides
The immobilization of a whole microbial cell is an important process used in nanotechnology of biosensors and other related fields, especially the development of bio-hybrid materials based on live organisms and inorganic compounds. Here, we described an essay to develop a bio-hybrid material based on Salmonella Typhimurium cells and layered double hydroxides (LDH). The synthetic clays have a good capacity to be a host...
