“…These compounds not only disrupt the fungal hyphae to reduce the rate of mycelial growth, but also reduce the rate of spore germination and, in some cases, restrict the germ tube elongation of the germinated spores [47,48]. Specifically, recent studies have reported the antimicrobial activity of volatile amine derivatives against some important fungal and bacterial pathogens [37,51]. For instance, several soil-born Bacillus spp.…”

“…For instance, PGPB can emit VOCs as biocontrol factors or a deterrent against plant pathogenic fungi and other competing bacteria species to protect the host plant [27,29,30]. They could also act as autoinducers to enhance the proliferation of other beneficial microbes [34][35][36][37]. Recent advances in analytical science such as the headspace solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS), have enabled the extraction, identification, and characterization of VOCs emitted by PGPB and other bacterial species [30,38,39].…”

Antifungal Activity of Volatile Organic Compounds from Bacillus velezensis CE 100 against Colletotrichum gloeosporioides

et al. 2022

Colletotrichum gloeosporioides is the most prevalent phytopathogen, causing anthracnose disease that severely affects the production of various fruit trees, including walnut and jujube. In this study, the volatile organic compounds (VOCs) from Bacillus velezensis CE 100 disrupted the cell membrane integrity of C. gloeosporioides and reduced the spore germination by 36.4% and mycelial growth by 20.0% at a bacterial broth concentration of 10%, while the control group showed no antifungal effect. Based on the headspace solid-phase microextraction/gas chromatography-mass spectrometry (HS-SPME/GC-MS) analysis, seven VOCs were identified from the headspace of B. velezensis CE 100. Out of the seven VOCs, 5-nonylamine and 3-methylbutanoic acid were only detected in the headspace of B. velezensis CE 100 but not in the control group. Both 5-nonylamine and 3-methylbutanoic acid showed significant antifungal activity against the spore germination and mycelial growth of C. gloeosporioides. Treatment with 100 µL/mL of 5-nonylamine and 3-methylbutanoic acid suppressed the spore germination of C. gloeosporioides by 10.9% and 30.4% and reduced mycelial growth by 14.0% and 22.6%, respectively. Therefore, 5-nonylamine and 3-methylbutanoic acid are the potential antifungal VOCs emitted by B. velezensis CE 100, and this is the first report about the antifungal activity of 5-nonylamine against C. gloeosporioides.

“…Other signal molecules, with functions similar to AHL, have been reported in studies such as those by Orozco-Mosqueda et al, Velázquez-Becerra et al, and Martínez-Cámara et al [149] , [150] , [151] . These studies have identified and characterized volatile molecules such as dimethylhexadecylamine, produced by the curl-and endobacterium Arthrobacter agilis UMCV2, which may play an important role in communicating with other beneficial taxa in the rhizosphere or the endosphere of plants, since this molecule has an antifungal action and modulates the growth and swarming motility of other bacterial species, among other stimulating activities of plant growth and nutrition.…”

“…The outcomes of volatile-based microbial interactions, in general, have been recently reviewed (Schmidt et al, 2015;Tyc et al, 2017). However, when dealing with interactions involving bacilli, information is scarce concerning possible changes in VOCs production upon cross-talk or perception of volatiles produced by other microorganisms (Chen et al, 2015;Tahir et al, 2017;Martínez-Cámara et al, 2019). Thus, we focus hereafter on interactions based on cross-talks mediated by the perception of soluble metabolites.…”

Bacillus Responses to Plant-Associated Fungal and Bacterial Communities

2020

Some members of root-associated Bacillus species have been developed as biocontrol agents due to their contribution to plant protection by directly interfering with the growth of pathogens or by stimulating systemic resistance in their host. As rhizosphere-dwelling bacteria, these bacilli are surrounded and constantly interacting with other microbes via different types of communications. With this review, we provide an updated vision of the molecular and phenotypic responses of Bacillus upon sensing other rhizosphere microorganisms and/or their metabolites. We illustrate how Bacillus spp. may react by modulating the production of secondary metabolites, such as cyclic lipopeptides or polyketides. On the other hand, some developmental processes, such as biofilm formation, motility, and sporulation may also be modified upon interaction, reflecting the adaptation of Bacillus multicellular communities to microbial competitors for preserving their ecological persistence. This review also points out the limited data available and a global lack of knowledge indicating that more research is needed in order to, not only better understand the ecology of bacilli in their natural soil niche, but also to better assess and improve their promising biocontrol potential.
