1. Estruturacao de cristais de gelo em solucoes aquosas contendo solutos diversos.
Existe uma grande demanda de conhecimento na area de criopreservacao de frutos tropicais com vistas a reduzir os danos celulares provocados por cristais de gelo durante o congelamento. O objetivo deste trabalho foi estudar a capacidade de estruturacao de cristais de gelo. Solucoes aquosas contendo arabinose, glicose, piridoxina, creatina, metionina, lisina e

2. Otimização da liofilização do pericárdio bovino com o auxílio de ferramentas matemáticas / Freeze-drying optimization of bovine pericardium by mathematical modeling
Freeze-drying is a method of preservation that provides high-quality dehydrated products. It is a process that requires time and energy and it may take days to finish. Freeze-drying optimization is used to minimize the process time keeping the high quality of the product. Mathematical models that predict the behavior of products during freeze-drying can dras

3. Liquid Nitrogen Preservation of Saccharomyces carlsbergensis and its Use in a Rapid Biological Assay of Vitamin B6 (Pyridoxine)
Growth medium as well as freezing menstruum greatly influenced the recovery of Saccharomyces carlsbergensis when it was quickly frozen in liquid nitrogen at — 196 C and quickly thawed at 40 C. Nearly 90% recovery in viability was obtained when S. carlsbergensis was grown in Trypticase Soy Broth and frozen in vitamin B6 basal assay medium. The growth phase
