“…Most of the culturable soil microorganisms produce VOCs (Linton and Wright 1993), and it is assumed that similar mVOCs are the main contributors to total soil VOC production (Stotzky and Schenck 1976). Some VOCs are characteristically produced by specific phylogenetic groups or species and can therefore be used for taxonomic purposes (Larsen and Frisvad 1995a, c;Fischer et al 1999).…”

“…Volatile organic compounds emitted by plant roots (and associated mycorrhiza) or seedlings were identified, and suggestions for their functions were proposed (Kesselmeier and Staudt 1999;Wenke et al 2009). Interactions between plants and microbes mediated by VOCs as well as plant VOC production, measurement, and the influences of VOCs on plants have been discussed in several reviews (Stotzky and Schenck 1976;Linton and Wright 1993;Peñuelas and Llusià 2001;Cape 2003;Tholl et al 2006) and are far beyond the scope of this review.…”

“…Similar to PLFAs, ergosterol, DNA, and other biomarkers, microorganisms are also responsible for producing microbial volatile organic compounds (mVOCs) in high diversity and quantity (e.g., Linton and Wright 1993;Isidorov and Jdanova 2002;Wheatley 2002;Leff and Fierer 2008) and for different purposes. Volatile organic compounds are available to the analyzer without tedious sample pretreatment and extraction, and for this reason, the measurement may not present biases, and might be of virtue compared to measurement of PLFAs, DNA, and other microbial biomarkers.…”

Volatile organic compounds (VOCs) in soils

2010

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.

“…The detection of volatile organic compounds (VOCs) by various approaches has long been practised (e.g. Brown 1922 cited in Linton and Wright 1993), but recently, new detection methods have increased the potential of such studies. In addition to molecular tools targeting microbial community structure, VOCs may help to detect the presence of certain microorganisms as microbial VOCs emerge from various habitats like soil (Schade and Custer 2004;Asensio et al 2007a), litter (Leff and Fierer 2008), food (Börjesson et al 1990(Börjesson et al , 1992Kershi et al 1998;Schnürer et al 1999;Gao and Martin 2002;Mayr et al 2003), composts (Wheatley et al 1997;Fischer et al 1999;Smet et al 1999), buildings (Wilkins et al 2000;Fischer and Dott 2003;Matysik et al 2008), plant surfaces (Tirranen and Gitelson 2006), domestic biowaste (Mayrhofer et al 2006), arctic ice (Dickschat et al 2005a), seawater (Dickschat et al 2005b) and air conditioning systems of cars (Rose et al 2000).…”

Substrate-induced volatile organic compound emissions from compost-amended soils

et al. 2010

The agronomic effects of composts, mineral fertiliser and combinations thereof on chemical, biological and physiological soil properties have been studied in an 18-year field experiment. The present study aimed at tracing treatment effects by evaluating the volatile organic compound (VOC) emission of the differently treated soils: non-amended control, nitrogen fertilisation and composts (produced from organic waste and sewage sludge, respectively) in combination with nitrogen fertiliser. Microbial community structure was determined by denaturing gradient gel electrophoresis (DGGE). Aerobic and anaerobic soil VOC emission was determined after glucose amendment using proton transfer reaction-mass spectrometry (PTR-MS). After inducing VOC production by substrate (glucose) addition and at the same time reducing oxygen availability to impair degradation of the produced VOCs, we were able to differentiate among the treatments. Organic waste compost did not alter the VOC emissions compared to the untreated control, whilst sewage sludge composts and mineral fertilisation showed distinct effects. This differentiation was supported by DGGE analysis of fungal 18S rDNA fragments and confirms earlier findings on bacterial communities. Three major conclusions can be drawn: (1) VOC patterns are able to discriminate among soil treatments.(2) Sewage sludge compost and mineral fertilisation have not only the strongest impact on microbial community composition but also on VOC emission patterns, but specific tracer VOCs could not be identified. (3) Future efforts should aim at a PTR-MS-linked identification of the detected masses.

Probiotic strains contribute to the functionality of foods during fermentation. In this present work, cereal‐mix was fermented with probiotic Pichia kudriavzevii OG32. Selected fermentation parameters and functional properties of the product were determined. The growth of Pichia kudriavzevii OG32 was supported by the cereal‐mix containing 1% salt and 0.2% red chili powder to counts of between 7.46 and 8.22 Log10 cfu/mL within 24 h. Pichia kudriavzevii OG32 increased the viscosity of cereal‐mix with the highest inoculum size (1.84x105cfu/ml) giving the highest viscosity of 1793.6 mPa.S. An inoculum size of 1.98 × 104 cfu/mL gave the most acceptable product based on the sensory evaluation by the panelist. Forty volatile compounds were identified in the fermented product, while acids (32.21%) and esters (32.37%) accounted for the largest proportions. The cereal‐based fermented product scavenged DPPH from 200 μmol/L methanolic solution by 55.71%. Probiotic yeast improved the sensory and some functional properties of cereal‐based substrate during fermentation. This is one of the first reports on the volatile composition of cereal‐based functional food produced with probiotic yeast.
