Bref résumé de la pièce de Bhāsa (3e s.de n.è.) intitulée « Le couronnement » . A travers 6 actes dont trois se passent sans la présence de Rāma sur scène, nous suivons le héros épique et ses alliés dans leur guerre contre le prince des démons (rākṣasa) Rāvaņa qui a kidnappé Sītā, l’épouse de Rāma. Parmi les personnages, citons les singes Hanumān, Sugrīva et Vālin, ainsi que le démon repenti Vibhīṣaņa ligués avec Rāma contre les démons Rāvaņa et son fils Indrajit. Après la mort de ceux-ci, Rāma est saisi par le doute : sa femme l’aurait-elle trompé avec son pire ennemi Rāvaņa ? Ulcérée, Sītā veut se jeter dans les flammes, mais le dieu du feu Agni intervient pour la sauver, et les deux époux révèlent à tous leur vraie identité. Ils sont Viṣņu et Laksmī. Au dernier § se trouve une liste de 26 épithètes attribuées à Rāma par les protagonistes du drame. [less ▲]

A total of 375 lactic acid bacteria were isolated from fermenting cassava in South Africa, Benin, Kenya and Germany, and were characterised by phenotypic and genotypic tests. These could be divided into five main groups comprising strains of facultatively heterofermentative rods, obligately heterofermentative rods, heterofermentative cocci, homofermentative cocci and obligately homofermentative rods, in decreasing order of predominance. Most of the facultatively heterofermentative rods were identified by phenotypic tests as presumptive Lactobacillus plantarum-group strains, which also comprised the most predominant bacteria (54.4% of strains) isolated in the study. The next predominant group of lactic acid bacteria (14.1% of total isolates) consisted of obligately heterofermentative rods belonging either to the genus Lactobacillus or Weissella, followed by the heterofermentative cocci (13.9% of isolates) belonging to the genera Weissella or Leuconostoc. Homofermentative cocci were also isolated (13.3% of isolates). Biochemical properties such as production of alpha-amylase, p-glucosidase, tannase, antimicrobials (presumptive bacteriocin and H2O2-production), acidification and fermentation of the indigestible sugars raffinose and stachyose, were evaluated in vitro for selection of potential starter strains. A total of 32 strains with one or more desirable biochemical properties were pre-selected and identified using rep-PCR fingerprinting in combination with 16S rRNA sequencing of representative rep-PCR cluster isolates. Of these strains, 18 were identified as L. plantarum, four as Lactobacillus pentosus, two each as Leuconostoc fallax, Weissella paramesenteroides and Lactobacillus fermentum, one each as Leuconostoc mesenteroides subsp. mesenteroides and Weissella cibaria, while two remained unidentified but could be assigned to the L. plantarum-group. These strains were further investigated for clonal relationships, using RAPD-PCR with three primers, and of the 32 a total of 16 strains were finally selected for the development as starter cultures for Gari production.

Plusieurs années d’efforts de recherches témoignent que l’élevage des ovins Djallonké est une activité majeure dans l’Afrique subsaharienne, si l’on en juge par la masse des connaissances produites. Les auteurs, au travers d’un inventaire des différentes contributions scientifiques et techniques de 1967 à 2004, rapportent les performances de reproduction et de croissance des ovins Djallonké et les facteurs de leur variation. Les performances de reproduction ont été évaluées au travers de six critères zootechniques : cyclicité sexuelle annuelle, précocité sexuelle, intervalle entre agnelages, productions laitières, prolificité et mortalité des agneaux. Les performances de croissance ont été étudiées pendant deux périodes : la période d’allaitement naturel (croissance entre naissance et sevrage) et la période post sevrage. Les estimations des paramètres génétiques (héritabilité, corrélations génétiques et phénotypiques, répétabilité) de quelques caractères de reproduction et de croissance, ainsi que les résultats d’amélioration génétique, ont été passés en revue. Les conseils pratiques sont loin d’être uniformes étant donné la grande diversité des conditions d’expérimentation et d’analyse entre les différentes publications. [less ▲]

In the framework of a North Sea and adjacent areas monitoring, metallothioneins (MTs) have been studied in livers and kidneys of 8 marine mammals species collected on the Belgian coast and in the Northeast Atlantic between 1993 and 2000: the harbour porpoise Phocoena phocoena , the harbour seal Phoca vitulina, the white beaked dolphin Lagenorhynchus albirostris, the white sided dolphin Lagenorhynchus acutus, the sperm whale Physeter macrocephalus, the fin whale Balaenoptera physalus, the common dolphin Delphinus delphis and the striped dolphin Stenella coeruleoalba. The participation of this protein in metal detoxification has been investigated since high levels of cadmium (Cd) and mercury (Hg) have been measured in livers and kidneys of those marine mammals. It appears that MT concentrations vary widely in marine mammals tissues (from 50 to more than 2000 µg.g–1 dw) underlying the numerous parameters involved: species, tissue, physiological status, pregnancy, age, diet and metal level. The percentage of the cytosolic Cd bound to MTs can reach almost 100%. On the contrary, the percentage of hepatic and renal Hg bound to MT is very low (generally less than 10 %) and this metal is mainly associated with selenium (HgSe) under a detoxified form in the insoluble fraction of the tissues. Characterisation of renal MTs of white-sided dolphin has been performed: the protein has two isoforms (MT-1 and MT-2) with a molecular weight estimated around 6800. MT-1 can bind Cu, Zn, Hg and Cd while MT-2 only binds Zn, Hg and Cd suggesting different metabolic functions for the two isoforms. MT-2 was also more abundant than MT-1. To conclude, MTs appear to play a minor role in the binding and detoxification of Hg by marine mammals. On the contrary, close and dynamic interactions occur between Cd and MTs. White-sided dolphin metallothioneins has two isoforms likely characterised by different metabolic functions in relation with cellular homeostasis and cadmium detoxification. [less ▲]

Some green microalgae synthesize secondary carotenoids as protecting agents under stress. These pigments have high value as feed supplement for aquaculture and as health products. The most promising pigment is astaxanthin, because of its antioxidant, antitumoral and anti-inflamatory properties. The most used natural source of this pigment is the microalga Haematococcus pluvialis. However this species grows slowly and lacks robustness for easy cultivation. Therefore, other species are investigated for astaxanthin production. Here, we identified a locally isolated strain as Coelastrella sp. that is a secondary carotenoid producer. [1] A known typical feature of this genus, that we could observed in the strain by scanning electron microcopy, is the presence of meridional ribs. [2] We analyzed the culture conditions and concluded that this strain grows both autotrophically and heterotrophically and is able of fast change in pigment composition under controlled stress conditions. Thanks to HPLC analyses, we determined that the strain accumulates a variety of secondary carotenoids, among which: astaxanthin, cantaxanthin and echinenone. Unidentified compounds will be further analyzed by mass spectrometry. [less ▲]

Myrosinase from Brevicoryne brassicae was purified by ammonium sulfate fractionation, dialysis, and chromatography on a DEAE column. The chromatography yielded a single peak and a 115.6-fold purification. Further FPLC gel filtration gave a single peak at 120 kDa. Denaturing SDS/PAGE of the protein revealed a single band at 60 kDa, indicating that the native B. brassicae myrosinase is a dimer. Kinetic parameters towards 8 glucosinolates were calculated. Strong differences of V-max and Km were observed depending on the substrate. Degradation products of each glucosinolate were identified and quantified by GC-MS and GLC-FID, respectively. Using both crude aphid homogenates and purified myrosinase, two unique hydroxyglucosinolates, 3-butenyl- and benzyl-isothiocyanates were identified from progoitrin ((2S)-2-hydroxybut-3-enyl-glucosinolate) and sinalbin (4-hydroxybenzyl-glucosinolate) degradation respectively. Addition of ascorbic acid to the reaction mixtures containing sinalbin and progoitrin caused the production of hydroxyloted degradation products usually associated with plant myrosinase metabolisation. The occurrence of the myrosinase system in B. brassicae is discussed in terms of similar allelochemical adaptation between the herbivore and its host plant. (C) 2002 Wiley-Liss, Inc. [less ▲]
