IX.: PARASITIC COPEPODS FROM NANAIMO, BRITISH COLUMBIA, INCLUDING EIGHT SPECIES NEW TO SCIENCE.: (WITH SEVEN PLATES)—PLATES III-IX.

The Enzymic Conversion of Protoporphyrinogen IX to Protoporphyrin IX

The oxidation of protoporphyrinogen IX to protoporphyrin TX in yeast cells is enzyme-dependent. The enzyme, protoporphyrinogen oxidase, associated with purified mitochondria isolated from Saccharomyces cereuisiae was solubilized by sonic treatment in the presence of detergent and partially purified. The molecular weight of the enzyme was 180,000 f 18,000. The purified preparation could be store...

Antibiotic Substances from Basidiomycetes Ix

Groundwater cyclopoid copepods of peninsular India, with description of eight new species.

To date, only three stygobiotic cyclopoid species are known from India: Haplocyclops (Kiefercyclops) fiersi Karanovic & Ranga Reddy, 2005 and Rybocyclops dussarti Ranga Reddy & Defaye, 2008, from bores, and Allocyclopina inopinata Defaye & Ranga Reddy, 2008, from brackish conditions of a hyporheic habitat. Analysis of numerous groundwater samples collected during 2008-2013 from the hyporheic an...

Part IX . A New Diterpene Alcohol from cyptomria D . Don

In continuation of earlier works1) an unknown compound, C20H340, m・P・ 182~183。, [α]15D +14.52°,obtained from the neutral portion of wooe resin of Cryptmeria japonica D. Don, has been examined. In part VIII1) of this series, an isolation of this compound has been described in detail. This compound, called phyllocladanol, is not apparent to have been previously isolated. Phyllocladanol is colorle...

Characterization of Legionella Species from Watersheds in British Columbia, Canada

Legionella spp. present in some human-made water systems can cause Legionnaires' disease in susceptible individuals. Although legionellae have been isolated from the natural environment, variations in the organism's abundance over time and its relationship to aquatic microbiota are poorly understood. Here, we investigated the presence and diversity of legionellae through 16S rRNA gene amplicon ...
