Cladosporium sp. Isolate as Fungal Plant Growth Promoting Agent

Cladosporium species are active in protecting plants against different biotic and abiotic stresses. Since these produced a wide range of secondary metabolites responsible for the adaptation to new habitats, plant health performance, they great interest, especially biostimulants agriculture. sp. produces protein hydrolysates (PHs), class biostimulants, by cultivation on medium with keratin wastes (feathers) as carbon energy sources. The aim this study was select isolate potential be used growth promoting agent. characteristics isolates were evaluated through several tests, such as: antagonism versus pathogens, effect secreted volatiles isolates, secretion hydrolytic enzymes, production 3-indole acetic acid, zinc phosphorous solubilization, capacity promote tomato seedlings (pot experiments). T2 presented positive results all tests. Encouraging obtained treating PHs from cultured supplemented 1% (w/w) chicken feathers, which parameters, stem weight, height, root weight significantly higher 65%, 32%, 55%, respectively, compared those treated water.
