    Notes: Abstract: This paper presents challenging opportunities for production of liquid and gaseous fuels by biotechnology. From the liquid fuels, ethyl alcohol production has been widely researched and implemented. The major obstacle for large scale production of ethanol for fuel is the cost, whereby the substrate represents one of the major cost components. Various scenarios will be presented for a critical assessment of cost distribution for production of ethanol from various substrates by conventional and high rate processes. The paper also focuses on recent advances in the research and application of biotechnological processes and methods for the production of liquid transportation fuels other than ethanol (other oxygenates; diesel fuel extenders and substitutes), as well as gaseous fuels (biogas, methane, reformed syngas). Potential uses of these biofuels are described, along with environmental concerns which accompany them. Emphasis is also put on microalgal lipids as diesel substitute and biogas/methane as a renewable alternative to natural gas. The capturing and use of landfill gases is also mentioned, as well as microbial coal liquefaction. Described is also the construction and performance of microbial fuel cells for the direct high-efficiency conversion of chemical fuel energy to electricity. Bacterial carbon dioxide recovery is briefly dealt with as an environmental issue associated with the use of fossil energy.

    Notes: Summary An optimum initial molar C/N ratio of about 77 was found for maximum lipid production from glucose or fructose with a nitrogen source from either (NH4)2SO4, NH4NO3 or urea. The fatty acid composition of the lipids was affected by the initial C/N ratio and by the type of sugar but not significantly by the type of nitrogen.

    Description / Table of Contents: Zusammenfassung Das Verhalten von In, Sn und Sb bei Extraktion aus Jodwasserstoffsaurem bzw. salzsaurem Milieu wurde untersucht und einzelne Trennungsverfahren ausgearbeitet. Die Trennung von Sb(V) und Sn(IV) erfolgt durch Extraktion des Antimons aus 7-m Salzsäure mit Isoamylacetat. Die selektive oder gemeinsame Trennung der Ionen Sn(IV) und In(III) von Sb(V) gelingt durch Extraktion mit Benzol oder Isopropyläther aus jodwasserstoffsaurer Lösung. Diese Extraktionen sind einfach, rasch durchführbar und wirksam und daher geeignet für die Untersuchung kurzlebiger Spaltprodukte.
    Abstract: Résumé On a étudié le comportement vis-à-vis de l'extraction de In, Sn et Sb dans les milieux HI et HCl et l'on a développé plusieurs procédés de séparation. On a réalisé la séparation de Sb(V) d'avec Sn(IV) par extraction de Sb(V) par l'acétate d'isoamyle à partir d'une solution HCl 7M. On a effectué la séparation sélective de Sn(IV) ou de In(III), ou des deux, d'avec Sb(V), par extraction par le benzène ou l'éther isopropylique à partir des solutions HI. Les extractions sont très simples, rapides et efficaces, et par conséquent d'une grande utilité dans l'étude des produits de fission à courte durée de vie.
    Notes: Summary The extraction behaviour of In, Sn and Sb in HI and HCl media has been investigated and several separation procedures have been developed. Removal of Sb(V) from Sn(IV) is accomplished by extraction of Sb(V) from 7M HCl solution with isoamylacetate. Selective removal of Sn(IV) or In(III), or both, from Sb(V) is effected by extraction with benzene or isopropylether from HI solutions. The extractions are quite simple, rapid and efficient and therefore useful in the study of short-lived fission products.

    Notes: Summary The de-emulsifying ability of two bacteria (i.e.,N. amarae andC. petrophilum) has been demonstrated on water-in-oil petroleum field emulsions. De-emulsification by whole cultures and by washed cells was correlated with changes in the culture during growth. For each species, there was a particular growth phase which produced a species-dependent de-emulsification optimum.

    Notes: Summary Corynebacterium lepus produced a considerable amount of extracellular surfactant during growth in a mineral salts medium containing hexadecane as the sole carbon source. The study revealed that the bacterium also produced a large amount of surfactant when grown on glucose, but in this case the surface active agent was cell bound. The surfactant was released from the cells when they were treated with hexadecane after growth. Tetradecane also showed a good capability for release of the surfactant. Decane and octane were less effective than hexadecane and tetradecane.

    Notes: Summary Using cells ofCorynebacterium petrophilum andTorulopsis bombicola petroleum water-in-oil emulsions could be broken. The rate of deemulsification increased with an increase in cell concentration. Both ethanol and toluene are good cell carriers but water can not be used for this purpose.

    Notes: Summary Nocardia amarae has been shown to be a potent biological de-emulsifier of model oil-in-water emulsions and petroleum water-in-oil field emulsions. N. amarae is reported here to de-emulsify petroleum oil-in-water field emulsions. Parameters affecting the growth and the de-emulsifying ability of this bacterium have been examined. Bacteria-induced de-emulsifying activity could be useful in clarifying tailings ponds and sludges.
