    Notes: The wild strain and the astaxanthin-overproducing mutant strain 25–2 of Phaffia rhodozyma were analyzed in order to assess their ability to grow and synthesize astaxanthin in a minimal medium composed of g L−1: KH2PO4 2.0; MgSO4 0.5; CaCl2 0.1; urea 1.0 and supplemented with date juice of Yucca fillifera as a carbon source (yuca medium). The highest astaxanthin production (6170 μg L−1) was obtained at 22.5 g L−1 of reducing sugars. The addition of yeast extract to the yuca medium at concentrations of 0.5–3.0 g L−1 inhibited astaxanthin synthesis. The yuca medium supported a higher production of astaxanthin, 2.5-fold more than that observed in the YM medium. Journal of Industrial Microbiology & Biotechnology (2000) 24, 187–190.

    Description / Table of Contents: Résumé Vingt-quatre bouvillons de 11 mois de race Nellore pesant au début de l'expérience 120 kg ont reçu trois rations différentes dans une expérience d'une durée de 192 jours totalement conduite par blocs choisis au hasard. Les animaux pâturaient continuellement soit sur l'herbe de Yaragua (Hyparrhenia rufa) soit sur un mélange Yaragua/Stylosanthes (Stylosanthes guianensis). Ils ont reçu les rations suivantes: A—troupeau-témoin, Yaragua et sel ordinaire; B—mélange Yaragua/Stylosanthes, plus sel ordinaire; C—mélange Yaragua/Stylosanthes, plus phosphate bicalcique et sel ordinaire (dans le rapport de 1/1 pour ces derniers). La consommation moyenne minérale dans les trois groupes était de 52 g par animal et par jour. A 13 mois, les gains quotidiens en poids vif par bouvillon étaient respectivement de 0,182–0,409 et 0,483 kg pour les rations à base de Yaragua Yaragua/Stylosanthes et Yaragua/Stylosanthes plus mélange phosphate calcique et sel ordinaire. Le gain de poids vif quotidien par hectare était de 0,488–1,289 et 1,522 kg par bouvillon pour les mêmes rations (Yaragua/Stylosanthes plus sel ordinaire, Yaragua/Stylosanthes plus phosphate bicalcique et sel ordinaire. Les bouvillons recevant une légumineuse (Stylosanthes) dans leur régime ont eu des gains pondéraux deux fois supérieurs (P〈0,05) à ceux des témoins, le phosphate bicalcique quant à lui apportant un accroissement supplémentaire (P〈0,05).
    Abstract: Resumen En un experimento el cual tuvo una duración de 392 días, 24 novillos Cebú Nellore de un año de edad, los cuales pesaron 180 kg inicialmente, fueron asignados al azar a tres tratamientos diferentes. Los animales pastorearon continuamente pasto yaragua (Hyparrhenia rufa) o yaragua + stylo (Stylosanthes quianensis), recibiendo los siguientes tratamientos: a) control, yaragua + sal; b) yaragua +Stylosanthes + sal; c) yaragua + stylo + fosfato dicálcico y sal comun 1:1. El consumo mineral en los tres grupos fue en promedio 52 g animal/día−1. A los 13 meses de edad, la ganancia animal día fue de 0.182, 0.409 y 0.483 kg para los tres tratamientos en su orden. La ganancia de peso diaria por hectárea fue de 0.488, 1.289 y 1.522 kg novillo−1 para yaragua, yaragua + stylo + sal comun y yaragua + stylo + fosfato dicálcico con sal comun. Los novillos que recibieron leguminosas en la dieta, más que doblaron en ganancia de peso (P〈0.05) a los controles, y aun más (P〈0.05) los animales que recibieron fosfato dicálcico en la dieta.
    Notes: Summary Twenty-four yearling 11-month old Nellore steers initially weighing 180 kg were assigned to three treatments in a randomised complete block experiment lasting 392 days. Animals grazed continuously either Yaragua grass (Hyparrhenia rufa) or Yaragua/Stylo legume (Stylosanthes guianensis) and received the following treatments: A) Control, Yaragua plus common salt, B) Yaragua/Stylo plus common salt, and C) Yaragua/Stylo plus dicalcium phosphate/common salt (1:1). Mineral consumption in the three groups averaged 52 g per animal day−1. At 13 months daily liveweight gains/steer were 0.182, 0.409 and 0.483 kg for treatments of Yaragua, Yaragua/Stylo, and Yaragua/Stylo plus dicalcium phosphate/common salt mixture. Daily liveweight gains per ha were 0.488, 1.289, and 1.522 kg steer−1 for Yaragua, Yaragua/Stylo plus common salt and Yaragua/Stylo plus dicalcium phosphate/common salt. Steers receiving a legume (stylo) in the diet more than doubled weight gains (P〈0.05) compared to controls with dicalcium phosphate further (P〈0.05) increasing these gains.
