Ano: 1983 URL: http://www.documentation.ird.fr/hor/fdi:010004995 A lactic acid bacterium with potential application in cassava fermentation IRD Giraud, Eric; Brauman, Alain; Kéléke, S.; Gosselin, Laurent; Raimbault, Maurice. An amylolytic lactic acid bacterium, identified as #Lactobacillus plantarum$, was isolated from cassava roots (#Manihot esculenta$ var. Ngansa) during retting. Cultured on starch, the strain displayed a growth rate of 0.43 per hour, a biomass yield of 0.19 g/g, and a lactate yield of 0.81 g/g. The growth kinetics were similar on starch and glucose. Enough enzyme was synthesized, and starch hydrolysis was not a limiting factor for growth. The synthesized amylolytic enzyme was purified by fractionated precipitation with ammonium sulfate and by anion exchange chromatography. It was identified as an alpha-amylase with an optimal pH of 5.5 and an optimal temperature of 65°C. The use of such a strain as a cassava fermentation starter for gari production had the...

Ano: 1974 URL: http://www.documentation.ird.fr/hor/fdi:07406 Agrobacterium tumefaciens gene transfer to Casuarina glauca : a tropical nitrogen-fixing tree IRD Le, Q.V.; Bogusz, Didier; Gherbi, H.; Lappartient, A.; Duhoux, Emile; Franche, C.. Transgenic calli of the tropical tree #Casuarina glauca$ were produced using #Agrobacterium tumefaciens$-mediated gene transfer. Hypocotyls, cotyledons and epicotyls were excised from 30-60-day old #Casuarina$ seedlings and cocultivated with #Agrobacterium$ strain C58C1(pGV2260) containing the binary vector BIN19GUSINT. Transformed calli were selected on nutrient medium supplemented with 0,5 microM NAA, 2,5 microM BA and 50 mg/l kanamycin. Some of the factors influencing T-DNA transfer to #C. glauca$ explants were studied. Optimal transformation rates were obtained when explants from 45-day old seedlings were cocultivated for 3 days in the presence of 25 microM acetosyringone. Transgenic buds differentiated on 10% of the calli grown on transformed...

Ano: 1996 URL: http://www.documentation.ird.fr/hor/fdi:010011871 Altered growth and development of Steinernema carpocapsae DD136 by Xenorhabdus nematophilus mutants IRD Jewell, J.B.; Dunphy, G.B.. La part prise par les lipides dans la croissance et le développement de #Steinernema carpocapsae$ DD 136 en culture monoxénique avec #Xenorhabiditis nematophilus$ ATCC 19061 a été étudiée en utilisant le milieu de culture "Biosys jaune d'oeufs" délipidé. L'extrait lipidique total du jaune d'oeuf et celui des phospholipides augmentent le taux de croissance et la production de juvéniles infestants (IJs). La phosphatidylcholine à une concentration de 0.05 g/100 ml, produit le maximum de nématodes et de IJs. Comparé au type sauvage, #X. nematophilus$ "Tn5 muté" présente un niveau élevé en lipase, réduit la production de IJs et diminue le taux de croissance et le développement des nématodes. Le milieu de culture initialement conditionné par la bactérie sauvage,...

Both in Indonesia and Vietnam, larval rearing of #Pangasius hypophthalmus$ remains problematic due to variable and generally low survival rates obtained. The first week represents the most critical period for these larvae and up to now the cannibalistic behaviour was considered as the main cause of mortality. In the present study, two experiments were carried out in order to better understand the evolution and causes of mortality of #P. hypophthalmus$ larvae from hatching up to 8 days of age and find out measures to improve survival rates. The first experiment was designed to evaluate the importance of cannibalism and differences in mortality when larvae from two different females were reared either in groups of 30 individuals or in isolated conditions (30...
