Scleredema diabeticorum is an uncommon skin disorder showing a diffuse, symmetrical, and non-pitting persistent induration developing initially on the nape. It usually occurs in patients with poorly controlled or insulin-resistant diabetes mellitus. We present a 57-year-old woman with scleredema diabeticorum with hemoglobin A1c 6.1% (normal, 4.7% 6.2%) and impaired glucose tolerance. Alcian blu...

Using enrichment procedures, 45 organic solvent-tolerant lipase producer bacterial strains were screened from areas contaminated by oil and organic solvents. Among the strains, 15 isolates exhibited extreme stability toward organic solvents and high lipolytic activity. The NEB-1 isolate which was later identified as Pseudomonas sp. strain NEB-1 by biochemical tests and 16S rDNA gene sequence an...

Four species of lactic acid bacteria (LAB) were isolated from homemade yoghurt samples and defined as Lactobacillus acidophilus Lactobacillus bulgaricus, Lactobacillus casei, and Lactobacillus plantarum. Each LAB isolate was tested for its tolerance to acidic environments at pH (7.0, 4.0, and 2.0). All lactobacilli isolated tolerated acid while L. bulgaricus was sensitive to pH 2.0. All four ba...

A pretreatment of the yeast, Candida oleophila, with 5 mM H(2)O(2) for 30 min (sublethal) increased yeast tolerance to subsequent lethal levels of oxidative stress (50 mM H(2)O(2)), high temperature (40 °C), and low pH (pH 4). Compared with non-stress-adapted yeast cells, stress-adapted cells exhibited better control of apple fruit infections by Penicillium expansum and Botrytis cinerea and had...
