Removal Ability and Resistance to Cinnamic and Vanillic Acids by Fungi

Abstract

Twelve fungal strains were assayed to investigate their resistance to cinnamic and vanillic acids and their ability to remove these compounds from a liquid medium. In a first step, the effect of the two aromatic acids (1 g/L) on the fungal growth kinetic was studied. The results were modelled through a logistic like function (Dantigny equation) to estimate τ, which is the time to the half-maximum colony diameter. The key findings of this part were as follows: (i) generally, cinnamic acid exerted a stronger effect than vanillic acid; (ii) aromatic acids exerted a delay on the growth of some fungi and only one strain (Athelia rolfsii) was completely inhibited. In the second part, fungi were assayed to investigate their ability to remove cinnamic and vanillic acids (ca. 350 mg/kg) from liquid media at pH 3.5. The results indicated that the most efficient fungi were Aspergillus niger and Lasiodiplodia theobromae.

Eco-Friendly Solution Based on Rosmarinus officinalis Hydro-Alcoholic Extract to Prevent Biodeterioration of Cultural Heritage Objects and Buildings

“…Hesperidin is a strong antifungal and is active against A. parasiticus , A. flavus , F. semitectum and P. expansum [ 47 ]. Vanillic acid exhibits antimicrobial activity against Enterobacter cloacae and E. hormaechei strains; further, it induces a delay in the development of Trichoderma spp., Athelia rolfsii , Phaeoacremonium parasiticum , A. niger and F. oxysporum [ 48 , 49 , 50 ]. The R. officinalis extract also contains other derivatives of caffeic acid, that could act as ligands for metal ions; thus, they react with peroxide radicals and stabilize free radicals.…”

“…The antifungal action of vanillic acid on L. theobromae , C. gloeosporioides , F. oxysporum , P. parasiticum , P. italicum , A. niger , A. alternate , and Trichoderma sp. recorded lower effects compared to ferulic acid and p-coumaric acid [ 144 ]. Regarding the antibacterial activity, vanillic acid influences both human bacterial pathogens and those from agriculture or food.…”

Novel cinnamic acid derivatives as a versatile tool for developing agrochemicals for controlling plant virus and bacterial diseases by enhancing plant defense responses

“…[7][8][9] Cinnamic acid is an aromatic carboxylic acid that occurs naturally in diverse plants, including vegetables, Cinnamomum cassia, fruits and other substances. 10 Many studies have found that cinnamic acid derivatives have promising biological activities, including antibacterial, [11][12][13] antifungal, [14][15][16] antiviral, 17 anti-inflammatory, 18 anticancer 19 and insecticidal, 20 as well as prominent herbicidal activity, 21,22 which has led to cinnamic acid attracting widespread attention from pharmaceutical chemists (Figure 1). Meanwhile, caffeic acid (3, 4-dihydroxy cinnamic acid) and ferulic acid (3-methoxy-4-hydroxycinnamic acid), as classic analogs of cinnamic acid, also possess an excellent antiviral profile in the fields of medicine and pesticides.…”
