“…The organic acids were extracted from decomposing rice straw by distilled water as described by Brinton (1998) with some modifications. The flasks were removed at 0, 15, 30 and 60 days interval, and 25 ml of distilled water was added to each flask, shaken for 30 min on a rotary shaker at 140 g, and filtered through Whatman No.1 filter paper.…”

The production of organic acids and changes during decomposition of rice straw amended with tricalcium phosphate (TCP) and Udaipur rock phosphate (URP) were studied under laboratory conditions. The organic C content of rice straw decreased and total N increased with time, resulting in a decrease in C:N ratio as the decomposition progressed. The pH decreased to acidic range in all the treatments on day 15, but became alkaline again later on. Soluble P increased at 15 days after incubation, declined later during decomposition, and was highest in the treatments containing TCP and Aspergillus awamori inoculation. Citric, oxalic, formic and maleic acids were detected during decomposition of rice straw and maximum amounts were present on day 15. Citric and oxalic acids were responsible mainly for P solubilization from TCP and URP; generally, citric acid was the most effective in P solubilization.

“…Apart from environmental factors that affect microorganisms and therefore the microbial VOC production, numerous factors impact VOC retention in soils, among them temperature, pH, and moisture content (Brinton 1998). As the vapor pressures of the different VOCs are different and correspond with temperature (Schade and Custer 2004).…”

Volatile organic compounds (VOCs) in soils

Soils may act as sources or sinks of volatile organic compounds (VOCs). Many of the formed VOCs are produced by microorganisms, and it would be a challenge to investigate soil microbial communities by studying their VOC profile. Such "volatilomics" would have the advantage of avoiding extraction steps that are often a limit in genomic or proteomic approaches. Abundant literature on microbially produced VOCs is available, and in particular novel detection methods allow additional insight. The aim of this paper was to give an overview on the current knowledge of microbial VOC emissions from soils.

“…Odors are emitted as moist aerosols when windrows are turned for aeration and may contain appreciable levels of volatile organic acids. 2 This odor emission restricts the installation of composting facilities near urban centers, and is a cause for concern because it attracts potential disease-transmitting vectors. Among these are sarcosaprophagous and/or coprophagous insects, especially flies, which become important as the nexus between different infectious foci and man and his products.…”

ObjectiveOdorous compounds produced at the biosolids composting plant in Bariloche (NW Patagonia) attract a variety of insects, mainly belonging to the order Diptera. In order to characterize these flies, collected specimens were taxonomically identified, their community characteristics were described and their sanitary and synanthropic importance and autochthonous or introduced character were determined. Methods Sampling was performed from October 1999 until March 2000. Adults were collected using an entomological net, and larvae and puparia were obtained from the composting material and incubated to obtain adults. Richness, abundance and sex ratio were calculated. Results A total of 9 taxa of Diptera were identified: Sarconesia chlorogaster, Phaenicia sericata, Calliphora vicina, Cochliomya macellaria, Ophyra sp, Muscina stabulans, Musca domestica, Sarcophaga sp and Fannia sp. Specimens of Anthomyiidae, Acaliptratae and one larva of Eristalis tenax were also found. Ophyra sp. was the most abundant taxa. All the captured Diptera belonged to introduced taxa. Most of them are considered to be eusynanthropic and/or hemisynanthropic and have sanitary importance as they may cause myiasis and pseudomyiasis. The high number of females registered and the finding of immature stages indicated that flies can develop their complete life cycle on biosolid composting windrows. ConclusionsThe characterization of flies obtained in this study may be useful for defining locations of urban or semi-urban composting facilities. It also highlights the importance of sanitary precautions at such plants.

Con el objeto de caracterizarlas, se colectaron especímenes que fueron identificados taxonómicamente. Se describieron sus características comunitarias y se determinó su importancia sanitaria y su carácter autóctono o introducido.7 2 3 7 2 3 7 2 3 7 2 3 7 2 3 Rev Saúde Pública 2003
