“…Microbial volatiles have strong diffusion and are often regarded as chemical-signaling molecules in many life activities [11]. Cao [12] found that actinomycete, Aguyces allii 130935, had an 89% nematocidal activity against M. incognita after 8 h and significantly reduced the root galls. Sphingosine was isolated from Bacillus cereus S2.…”

Pochonia chlamydosporia is widely applied in many countries as a biocontrol fungus against parasitic nematodes in plants. In a field experiment, the combined use of Bacillus nematocida B16 increased the biocontrol efficiency of P. chlamydosporia ZK7 against Meloidogyne incognita. Further study indicated that the colonization of P. chlamydosporia ZK7 in the rhizosphere soil and the roots of tomatoes was significantly higher in the combined use group than in the control group. Gas chromatography was conducted to determine the effects of signaling substances. Five compounds, hexanal, (E)-2-hexenal, furfural, benzaldehyde, and 2-nonanone, were found to be highly altered in the volatile compounds produced in the soil under the combined application. The changes in benzaldehyde and 2-nonanone were the main factors that resulted in an increase in the colonization of fungi P. chlamydosporia ZK7 in the tomato roots. Furfural was the main volatile substance that affected the colonization of fungi P. chlamydosporia ZK7 in the soil. The combined use of B. nematocida B16 and P. chlamydosporia ZK7 altered the volatile ranges and resulted in increased colonization of biocontrol fungi and improved biocontrol efficiency against nematodes. This combined model could be used to promote the ability of biocontrol fungi to control root-knot nematodes.

“…Few studies focused on managing PPNs with bacteria, 12 but Paenibacillus strains were described as having a deleterious effect on PPNs. 13 − 15 Paenibacillus is a cosmopolitan and ubiquitously occurring bacterial genus, which is predominantly isolated from the rhizosphere.…”

“…Due to their physico-chemical properties, VOCs can easily diffuse through gas-and water-filled pores and can therefore have a wide effective range in soil. 11 Few studies focused on managing PPNs with bacteria, 12 but Paenibacillus strains were described as having a deleterious effect on PPNs. 13−15 Paenibacillus is a cosmopolitan and ubiquitously occurring bacterial genus, which is predominantly isolated from the rhizosphere.…”

Volatile Organic Compounds from a Lichen-Associated Bacterium, Paenibacillus etheri, Interact with Plant-Parasitic Cyst Nematodes

Healthy food is one of the major challenges to develop in this century. Plant-parasitic nematodes cause significant damage to many crops worldwide and till now, the use of chemical nematicides is the main means to control their populations. These chemical products must be replaced by more environmental-friendly control methods. Biocontrol methods seem to be one promising option, and the number of biopesticides derived from living organisms has increased in the last decades. To develop new plant protection products, we have decided to combine our skills in natural products chemistry and nematology and to focus on the lichen microecosystem as underexploited ecological niches of microorganisms. We present herein the potential of lichen-associated bacterial suspensions from Paenibacillus etheri as nematicides against the beet cyst nematode Heterodera schachtii and the potato cyst nematode Globodera pallida, in particular the effects of volatile organic compounds (VOCs) produced by the bacteria. A solid phase micro-extraction method associated to gas chromatography−mass spectrometry analysis of 14 day cultures was used to analyze these VOCs in order to identify the main produced compounds (isoamyl acetate and 2phenylethyl acetate) and to evaluate them on the nematodes.
