We evaluated the effect of ultrasound radiation on lipase activity. The experiments were conducted using a low‐cost crude enzyme extract. We then used this lipase to treat dairy effluent. The results of our study presented an increase of approximately 430% in the concentration of free fatty acids. 相似文献

ABSTRACT: The aim of this paper is to present a multicriteria methodology for decision aid at the stage of programming a water supply system (WSS) for a rural area. The programming stage is an intermediate one between planning and designing water supply facilities, and can be decomposed into two problems: (a) setting up a priority order of water users, taking into account socio-economic criteria; and (b) choosing the best technical variant of the WSS. Among the criteria considered for the latter problem, there is a criterion of distance between the socio-economic priorities of users and the precedence orders of users according to the technical programming, which plays a coordinating role between problems (a) and (b). All steps of the presented methodology are illustrated by a real case study. 相似文献

This study examined behavioral and enzymatic changes of C. elegans from its exposure to aluminum, and the resulting relationship with Alzheimer's disease. After chronic and acute exposure to aluminum, the results indicated that it alters the cholinergic status and behavior parameters of the nematode, suggesting a relationship between exposure to aluminum and the etiology of AD. 相似文献

The southern Namib desert has a vegetation cover of mainly succulent plants in which species of the Mesembryanthemaceae are predominant. Climatically this area is characterized by hot and dry days, and cool and humid nights with episodic rainfalls only in winter. In this environment a great number of species perform a crassulaceaen acid metabolism (CAM). The responses of these plants to water stress as well as the regulation of CAM in the natural habitat are described and discussed. 相似文献

The intensive and abundant use of synthetic herbicides has been questioned in recent decades due to the strong dependence and also the resistance effects that are identified in weeds. Several grain crops suffer from the weed control system because many of the weeds are already resistant to the main herbicides that are used. In recent years, there has been a large gap in the market without the addition of new synthetic herbicides with mechanisms of action that differ from those already existing. The objective of this short piece is to address and overcome this challenge and bring an innovative and alternative solution that proposes a synergistic action system between bioherbicides produced by the fungus Trichoderma koningiopsis and synthetic herbicides (2,4‐dichlorophenoxyacetic acid, glyphosate, and ammonium glufosinate). The plants included in this study were Bidens pilosa (amor seco, or in the United States, beggar ticks or Spanish needle), Euphorbia heterophylla (adeus‐brasil), and Conyza bonariensis (margaridinha‐do‐campo, or, in the United States, hairy fleabane or asthmaweed). It was verified that, in the application of the biocomposites in the presence of chemical herbicides, potentiation of the phytotoxic action (100%) occurred under the target plants, emphasizing phytotoxicity to the weed, C. bonariensis, which is currently resistant to available herbicides. The bioherbicides studied have promising characteristics to be explored in the biocontrol of weeds. 相似文献
