胨冻样芽孢杆菌(Bacillus mucilaginosus)对烟草灰霉病菌(Botrytis cinerea)的抑制作用

本文首次报道胨冻样芽孢杆菌XDB1和D4B1对烟草灰霉病菌(Botrytis cinerea)的抑制作用。实验表明,XDB1和D4B1的发酵原液和无细胞提取物具有相同的抑菌效果,而经121℃处理30分钟后,抑菌活性丧失。D481菌株的抑菌活性高于XDB1,钾长石作为基质时的活性高于土壤矿物。但是,XDB1和D481对立枯丝核病菌(R..solani)、西瓜尖孢镰刀菌(F.oxysporum)、腐霉(Pythium sp)、小麦全蚀病菌(G.graminis)、烟炭疽病菌(C.gloeosporides)、烟草赤星病菌(A.alternata)、烟草黑胫病菌(P.nicotianae、串珠镰刀病菌(F.moniliforme)和水稻稻瘟病菌(P.grisea)无抑制作用。

Fire performance of wood (Pinus radiata) treated with fire retardants and a wood preservative

In this work, we co‐formulated an oil‐borne copper naphthenate/permethrin wood preservative system with synthetic polymer‐based fire‐retardant additives prior to the impregnation of Pinus radiata sapwood. We evaluated what effect, if any, the preservative had upon the fire performance properties of the fire retardants and whether the fire retardants impacted on the fungicidal and termiticidal efficacy of the preservative. The fire retardants included halogenated and phosphorus‐based systems. A mass loss calorimeter, in conjunction with a thermopile, was used to measure the time to ignition and the peak heat release rate (PHRR) from which the fire performance index (FPI) was determined. The preservative properties were evaluated using termite and soil‐block decay bioassays. In summary, we found that the rate of fire growth was reduced when the fire retardants were used in combination with the wood preservative. We also found that the PHRR was a better determinant of fire performance than the FPI. The performance of the wood preservative was enhanced against fungal decay and termite attack when used in combination with the fire retardants. The fire retardants also demonstrated some wood preservative properties of their own. Copyright © 2008 John Wiley & Sons, Ltd.

Information technology support in the chemical process design life cycle

Information technology has been becoming increasingly important in all areas of engineering during the last few years. Much of the progress achieved in chemical engineering would not have been possible without the enabling methods and tools provided by information technology. This trend will continue in the future but most likely with a considerably wider scope. While individual software tools and services have been in focus until recently, their integration into engineering work processes is an emerging and challenging area of research and development. This contribution attempts to highlight state of the art and future trends in supporting the activities during the life cycle of a chemical process by means of information technology. Emphasis will be largely on the process and plant design process rather than on procurement, manufacturing, and distribution of materials in the supply chain.     

Human urine - Chemical composition and fertilizer use efficiency

Stored human urine had pH values of 8.9 and was composed of eight main ionic species (> 0.1 meq L^–1), the cations Na, K, NH₄, Ca and the anions, Cl, SO₄, PO₄ and HCO₃. Nitrogen was mainly (> 90%) present as ammoniacal N, with ammonium bicarbonate being the dominant compound. Urea and urate decomposed during storage. Heavy metal concentrations in urine samples were low compared with other organic fertilizers, but copper, mercury, nickel and zinc were 10–500 times higher in urine than in precipitation and surface waters. In a pot experiment with¹⁵N labelled human urine, higher gaseous losses and lower crop uptake (barley) of urine N than of labelled ammonium nitrate were found. Phosphorus present in urine was utilized at a higher rate than soluble phosphate, showing that urine P is at least as available to crops as soluble P fertilizers.
