Abstract. Bacteria that produce siderophore were isolated from the coastal marine environment of the Seto Inland Sea, Japan. The siderophores were identified as a hydroxamate-type siderophore, aerobactin. The production of aerobactin was induced in the iron-limited conditions, and ...

Abstract. A gram-positive bacterium designed KP7 that was capable of growing on phenanthrene at 42°C was isolated. In this strain, 1-hydoxy-2-naphthoate, a common intermediate in phenanthrene-degradative pathways, was transformed to 2-carboxybenzaldehyde and o-phthalate. The activities ...

Abstract. The involvement of calcitonin gene-related peptide (CGRP) during transfer of seawater-adapted trout, Oncorhynchus mykiss, to fresh water was investigated by measuring the CGRP plasma concentration and the CGRP binding to gill membranes. The CGRP concentration shows a sharp ...

Abstract. Approximately 90% of the 14.5 million metric tons of aquaculture-produced animals in 1993 were reared using phytoplankton as a feed source during one or more stages. Worldwide aquaculture production is growing at 7.2% per annum, with trends toward intensification and greater ...

Abstract. The aim of this work was to evaluate the potential use of a fish hydrolysate as microbial substrate, and the effect of an increased (acidic) hydrolysis rate on the cell yield. With this objective, we compared E. coli growth kinetics on fish hydrolysates and on casein ...

Abstract. Thermostable dipeptidase was purified to homogeneity from soluble cytoplasmic extract of carp intestine with an increase in specific activity of 372-fold and a 2% recovery rate. The enzyme was determined to have molecular weights of 64,000 after reduction and 320,000 without ...

Abstract. We have recently cloned a teleost cDNA coding fibroblast growth factor 2 (FGF-2; also known as basic fibroblast growth factor). To explore the function of this FGF-2 in fish fin regeneration, we quantified the morphological pattern of the regeneration using computer image ...

Abstract. An efficient protocol for rooting and acclimation of in vitro propagated Ruppia maritima was the focus of this research. The effects of four dilutions of a nutrient medium (f) and four different concentrations of sodium bicarbonate on rooting production were investigated. The ...

Abstract. Although carp muscular and intestinal dipeptidases are metalloenzymes acting only on dipeptides, some structural and enzymatic differences occur between them. The present study verifies distinctive actions during dipeptide hydrolysis by these enzymes in terms of their kinetic ...

Abstract. Cultures of a species of Vibrio isolated from fish intestines and known to synthesize the polyunsaturated fatty acid eicosapentaenoic acid (20:5n-3) were incubated with di-[1-14C]palmitoyl phosphatidylcholine to determine if lipolytic enzymes are produced by the bacteria. After ...
