Physiological properties and proportion of typical features of Pityrosporum pachydermatis were determined on 385 strains from clinical cases of O.E and dermatitis in dogs. Carbohydrates and nitrogen assimilation were determined auxanographically. Urease production and enzyme release were assessed on Christensen's medium and API-ZYM respectively. All strains oxidised carbohydrates in the OF test. 90% assimilation of glucose and production of urease are typical of Pityrosporum, contrary to 100% positive reactions in literature data. Production of acid and alkaline phosphatases, phosphohydrolase, leucin arylamidase, and beta-glucosidase dominated, while lipase C14, esterase-lipase C8, esterase C14 and alpha-galactosidase were variable.

The agar-degrading bacterium GNUM-1 was isolated from the brown algal species Sargassum serratifolium, which was obtained from the West Sea of Korea, by using the selective artificial seawater agar plate. The cells were Gram-negative, 0.5-0.6 micrometer wide and 2.0-2.5 micrometer long curved rods with a single polar flagellum, forming nonpigmented, circular, smooth colonies. Cells grew at 20 degrees C- 37 degrees C, between pH 5.0 and 9.0, and at 1-10% (w/v) NaCl. The DNA G+C content of the GNUM-1 strain was 45.5 mol%. The 16S rRNA sequence of the GNUM-1 was very similar to those of Alteromonas stellipolaris LMG 21861 (99.86% sequence homology) and Alteromonas addita R10SW13 T (99.64% sequence homology), which led us to assign it to the genus Alteromonas. It showed positive activities for agarase, amylase, gelatinase, alkaline phosphatase, esterase (C8), lipase (C14), leucine arylamidase, valine arylamidase, alpha-chymotrypsin, acid phosphatase, naphthol- AS-BI-phosphohydrolase, alpha-galactosidase, beta-galactosidase, beta-glucosidase, catalase, and urease. It can utilize citrate, malic acid, and trisodium citrate. The major fatty acids were summed feature 3 (21.5%, comprising C16:1omega7c/iso- C15:0 2-OH) and C16:0 (15.04%). On the basis of the variations in many biochemical characteristics, GNUM-1 was considered as unique and thus was named Alteromonas sp. GNUM-1. It produced the highest agarase activity in modified ASW medium containing 0.4% sucrose, but lower activity in rich media despite superior growth, implying that agarase production is tightly regulated and repressed in a rich nutrient condition. The 30 kDa protein with agarase activity was identified by zymography, and this report serves as the very first account of such a protein in the genus Alteromonas.
