From Extraction to Stabilization: Employing a 2 Experimental Design in Developing Nutraceutical-Grade Bixin from L.

Bixin is the main carotenoid found in the outer portion of the seeds of L., commercially known as annatto. This compound is industrially employed in pharmaceutical, cosmetic, and food formulations as a natural dye to replace chemical additives.

Optimization of the cultivation conditions of BCLLNF-01 for cellulase production.

The objective of this study was to optimize the production of CMCase by BCLLNF-01, a strain associated with the mucus of the zoanthid (Cnidaria, Anthozoa). Production of total cellulase and CMCase was investigated in the supernatant, intracellular content and wall content. Cultivation was carried out in BLM medium supplemented with 1.

Physicochemical characterization of surfactant incorporating vesicles that incorporate colloidal magnetite.

Drug administration through the transdermal route has optimized for the comfort of patients and easy application. However, the main limitation of transdermal drug delivery is the impermeability of the human skin. Recent advances on improvement of drug transport through the skin include elastic liposomes as a penetration enhancer.

Production of concentrates of bacterial bio-insecticide Bacillus thuringiensis var. israelensis by flocculation/sedimentation.

Flocculation/sedimentation of Bacillus thuringiensis var. israelensis (Bti) using flocculating agents has been studied. Batch cell production was performed in an agitated tank, and the flocculation assays were carried out in jar tests.

Concentration of Cupriavidus necator cells by flocculation and sedimentation.

Separation and cells concentration constitute important stages in most biotechnological processes. Particularly, use of flocculation/sedimentation can improve significantly the extraction of biopolymers accumulated by microorganisms and the biodegradation of xenobiotic compounds by cell sludge. In this work the use of tannin and aluminum sulphate (Al2(SO4)3) as flocculating agents for concentration of cells of Cupriavidus necator DSM 545 is evaluated.
