“…A feature of these microorganisms that may be utilized as biofungicides is an ability to produce cell wall degrading enzymes (CDWE) active on fungi, such as chitinase, protease and glucanase (Chaiharn et al, 2019;Gohel et al, 2006;Maiden et al, 2017;Nakaew et al, 2015). Many studies came to a common conclusion that chitinase activity is a vital indicator for antifungal effectiveness, and a similar strategy can be observed in plant defence where increased expression of similar cell-wall degrading enzymes functions to break down the cell walls of the pathogens (Go et al, 2019;Sakpetch et al, 2018). In Bacillus sp., lipopeptides, including the surfactin, iturin, fengycin and bacillomycin families of antibiotics, were most likely responsible for antifungal activities of the bacterial species against R. microporus (He et al, 2017).…”

The rubber tree, Hevea brasiliensis (Willd. ex A. Juss.) Mull. Arg., is one of the most economically important industrial crops, producing the milky latex which is the source of the valuable global commodity natural rubber. Natural rubber provides a source of income for rural communities, especially in Southeast Asia (Singh et al., 2021;Vongkhamheng et al., 2016). Due to the high demand globally for rubber, the area of rubber plantations worldwide increased gradually from 3 million ha in 1961 to 12 million ha in 2019 (FAO 2022).Approximately 90% of global rubber production is dominated by smallholders and planted in monoculture (IRSG, International Rubber Study Group, 2019). A rubber small-holding is defined as contiguous or non-contiguous areas aggregating less than 40.47 hectares (100 acres) planted with the crop (Saufe & Man, 2017). 2021) reported that 96% of rubber production yields are explained by independent variables comprising labour, plantation area, weeding and other cultivation activities by the smallholders. Ramli et al. (In addition, the income of the smallholder farmers also determines rubber production at the local scale, where low profitability leads to reduced tapping activities and even abandonment of farms (Ali et al., 2021). The conversion of primary and secondary forests to rubber monoculture decreases species richness and impacts overall species composition (Gitz et al., 2020). The introduction of this monoculture to new ecosystems has also led to the spread of nonnative pathogens and diseases (Monkai et al., 2017). Arguably, the most economically important rubber disease is white root rot (WRR) disease.

Exploring the Potential Applications of Paecilomyceslilacinus 112

Microorganisms are widely used to obtain biostimulants that can facilitate the assimilation of nutrients, ensuring high crop yield and quality. A particular category of biostimulants are protein hydrolyzates (PH), obtained from microbial cultures grown on a nutrient medium. In the present study, Paecilomyces lilacinus 112, an endophytic fungus isolated from soil, was tested to determine its effect on the growth promotion of tomato seedlings in greenhouse conditions. Additionally, other beneficial features of the P. lilacinus isolate were evaluated via several tests: antagonism against plant pathogenic fungi, production of secondary useful metabolites, and solubilization of vital micronutrients. Out of the tested pathogens, P. lilacinus exhibited the highest antifungal activity against a Cladosporium isolate (inhibition of 66.3%), followed by Rhizoctonia. solani (52.53%), and Sclerotinia sclerotiorum (50.23%). Paecilomyces lilacinus 112 was able to secrete hydrolytic enzymes and siderophores, and solubilize zinc and phosphorus. In the tomato treatment, the application of PH obtained from fungal cultivation on a feather medium led to the following increases in plant growth parameters: 3.54-fold in plant biomass; 3.26-fold in plant height, 1.28-fold in plant diameter; 1.5-fold in the number of branches/plant; and 1.43-fold in the number of leaves/plant, as compared to water treatment. The application of this isolate can be of benefit to bioeconomy because keratin wastes are valorized and returned, in agriculture, contributing to renewable natural resources.
