The current study aimed at evaluate the effect of different inclusion levels Asparagus racemosus root meal on two hundred and twenty five (225) Clarias gariepinus juveniles. Five iso-nitrogenous diets 40% crude protein were formulated to contain A. (0.0, 0.5, 1.0, 1.5 2.0 g/kg) labelled as (DI-D5) with a triplicate each regime fifteen fish per tank. fingerlings fed visual satiation between 08:0...

A feeding trial was conducted to assess the effects of substituting melon (Citrullus lanatus) seed peel meal (MSPM) for yellow maize on haematological and serum biochemical indices Clarias gariepinus fingerlings 56 days. Fifteen fish each were stocked in eighteen plastic bowls (50-litre capacity) fed six iso-nitrogenous diets at graded MSPM levels 0%, 20%, 40%, 60%, 80% 100% twice daily 5% thei...

INTRODUCTION It is generally agreed that the most primitive type of nitrogenous excretory product, arising directly from the a-amino-N of proteins by deamination, is ammonia. In an extensive survey of the invertebrates, Delaunay (1927) was able to account for more than 50 % of the total non-protein nitrogen (N.P.N.) excreted in terms of ammonia in a large number of unrelated aquatic species, in...

The EPR spectra of the NO complexes of frozen solutions of ascorbic acid-reduced cytochrome oxidase (nitrite reductase) purified from Pseudomonas aeruginosa, of its heme d1-depleted form, and of heme d1 in solutions containing various nitrogenous bases are quite similar to each other as well as to several heme (iron protoporphyrin IX)-containing proteins. The NO complexes of heme d1 (an iron-ch...

This paper, although limited to the effects of homologous antibodies acting as inhibitors of the sporulation process of bacterial cells, is one of a series of current investigations of various physiological factors concerned in sporogenesis. The essentials for sporogenesis recently have been hypothesized and experimentally supported by Hardwick and Foster (1952). They point out, with good evide...

The endogenous substrate of Pseudomonas aeruginosa has been reported to be nitrogenous in nature, as was evident by the marked and quantitatively predictable production of ammonia during endogenous respiration and it was concluded that amino acids were the nitrogenous substrates involved. Further, it was shown that on the addition of an oxidizable substrate, the ammonia which had accumulated in...

Pappagianis, D. (University of California, Berkeley), E. W. Putman, and G. S. Kobayashi. Polysaccharide of Coccidioides immitis. J. Bacteriol. 82:714-723. 1961.-Soluble polysaccharide from mycelia or culture filtrates of Coccidioides immitis was found to consist mainly of mannose, but also included small quantities of galactose and another reducing sugar. Isolation of the polysaccharide by etha...

On the basis of experiments with tobacco, Crook (1946) has worked out a technique for the extraction of nitrogenous materials from leaves. Its usefulness has now been tested on leaves from other plants, although no attempt has been made to apply the technique to a comprehensive selection of plants. Those used had been brought to the laboratory for other studies or were conveniently available fr...

In Sterile Insect Technique (SIT) programs, mass-reared males of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), are maintained on a sugar-agar diet before their release into the environment. Several studies suggest that nitrogenous dietary supplements improve the mating competitiveness of the sterile males, thus increasing the cost effectiveness of SIT. Other research, however, ha...
