Effect of Carbon Sources on the Production of Volatile Organic Compounds by Fusarium verticillioides

Abstract

The aim of the present study was to evaluate the effect of different carbon sources on the hydrocarbon-like volatile organic compounds (VOCs) of Fusarium verticillioides strain 7600 through a Principal Component Analysis approach, and to explore their diesel potential by using data from the literature. The fungus was cultivated in GYAM culture medium, and five carbon sources were evaluated: glucose, sucrose, xylose, lactose, and fructose. The VOCs were collected using a close-loop apparatus and identified through GC-MS. The same profile of 81 VOCs was detected with all treatments, but with different relative percentages among carbon sources. The production of branched-chain alkanes (30 compounds) ranged from 25.80% to 38.64%, straight-chain alkanes (12 compounds) from 22.04% to 24.18%, benzene derivatives (12 compounds) from 7.48% to 35.58%, and the biosynthesis of branched-chain alcohols (11 compounds) was from 6.82% to 16.71%, with lower values for the remaining groups of VOCs. Our results show that F. verticillioides has the metabolic potential to synthesize diesel-like VOCs. Further research should include the optimization of culture conditions other than carbon sources to increase the production of certain groups of VOCs.

Effectiveness of Endophytic and Rhizospheric Bacteria from Moringa spp. in Controlling Pythium aphanidermatum Damping-Off of Cabbage

“…2,4-dimethylheptane has been reported as a VOC in Ficus tikoua [ 41 ] and fungi [ 42 , 43 ]. The production of 2,4-dimethylheptane by Fusarium verticillioides has also been documented [ 44 ]. Jia et al [ 45 ] demonstrated that the exogenous application of jasmonic acid enhanced the 4-methyloctane content in grapefruit and induced resistance against Botrytis cinerea .…”

Volatile Organic Compounds and Physiological Parameters as Markers of Potato (Solanum tuberosum L.) Infection with Phytopathogens

“…In this study, dimethyl disulfide was found in the sample infected with F. sambucinum (Table S1 and Table 3). Apart from terpenes, other fungal origin compounds were found, including hydrocarbons, acids, ketones, and alcohols [7,[50][51][52][53][54]. In the samples inoculated with C. coccodes and R. solani, a methylated derivative of benzene, i.e., 1,2,4-trimethylbenzene was detected, which was not found in other samples, including the control.…”

“…These organics were identified as volatile compounds produced by Muscodor suthepensis [56], Alternaria alternata [50], and Rhizoctonia solani and Trichoderma viride [57]. [56]; P [58,67] M [7,50,63]; P [61] M [7,52,61] M [7] M [53]; P [58] All compound numbers refer to the order in Table S1. * M-microbial, P-plant; # unknow origin.…”

Analysis of VOCs Emitted from Small Laundry Facilities: Contributions to Ozone and Secondary Aerosol Formation and Human Risk Assessment

“…Moreover, the comparison of dry-cleaning emissions with the organic solvent demonstrated that nonane seemingly increased from 14% to 35%, while decane and undecane seemingly decreased from 34% to 31% and from 25% to 13%. The compounds with low boiling points are generally characterized by the ability to evaporate into the atmosphere, mixing with air, and accumulation ability [ 50 ]. Besides that, Wang et al, (2013) [ 51 ] have previously confirmed that the evaporation rate of the solvent varied according to the difference in its boiling point.…”
