BACKGROUNDCitrus canker and citrus blue mold are two severe diseases in citrus plants, which are mainly caused by Xanthomonas citri susp. citri (Xcc) and Penicillium italicum, respectively. The currently widely used pesticides for these two diseases are harmful to human health and the environment. Therefore, searching for novel antimicrobial agents, especially from natural resources, is getting increasing interest.RESULTSIn this study, the crude extract of Streptomyces sp. GLL‐9, an endophyte from a navel orange tree, was found to exhibit excellent antimicrobial effects against Xcc and P. italicum. Bioassay‐guided isolation led to the discovery of three actinomycins (Acts), actinomycin X2 (Act‐X2), actinomycin D (ActD), and actinomycin XOβ (Act‐XOβ). The MIC (minimum inhibitory concentration) values of Act‐X2, ActD, and Act‐XOβ were 31.25, 62.50, and 62.50 μg mL−1 against Xcc, respectively, while 62.50 (Act‐X2) and 125.00 μg mL−1 (ActD) against P. italicum, being better or comparable to the positive controls. The highest yield of Acts was obtained by solid‐state fermentation with rice containing 1% L‐tryptophan as a culture medium, being 6.03, 3.07, and 1.02 mg g−1, for Act‐X2, ActD, and Act‐XOβ, respectively. The ethyl acetate extract of Streptomyces sp. GLL‐9 cultivated under the optimal fermentation conditions (EAE‐1) can efficiently control these two citrus diseases by excessively producing reactive oxygen species (ROS) in both pathogens, damaging the cell membranes of P. italicum, and inhibiting the growth of Xcc. In addition, Act‐X2, ActD, and EAE‐1 displayed broad‐spectrum antifungal activity.CONCLUSIONEAE‐1 and Acts produced by Streptomyces sp. GLL‐9 have high potential as novel antimicrobial agents against plant pathogens. © 2023 Society of Chemical Industry.

“…To reduce postharvest loss and maintain the quality of fruits and vegetables during storage and transportation, many scholars have developed convenient, effective, and safe storage technologies, such as film preservation (Fan et al., 2021), air conditioning (Li et al., 2022; Mahmood et al., 2019), irradiation (Guo et al., 2022; Zhao et al., 2020), pressure conditioning (Li et al., 2021), and biological preservation (Yang et al., 2022; Riesute et al., 2021). Among all such established techniques, film preservation has been widely applied in the preservation of apple (Liu et al., 2017), mushroom (Chen et al., 2021), mango (Zhang et al., 2019), and strawberry (Liu et al., 2022) owing to the advantages of easy operation, low‐cost, effectiveness in reducing evaporation and prevention of pathogen infection.…”

In the current study, a novel chitosan-based composite, carboxymethyl chitosan (CMCHS)/oxidized carboxymethyl cellulose (OCMC) was fabricated and characterized. The composite film (CMCHS 1.5%w/v + OCMC 0.8%w/v) was more uniform and had better tensile properties, UV blocking, water vapor permeability, and antifungal properties than pure CMCHS film. Preservation experiments showed that the CMCHS/OCMC film was more efficient for retaining the quality decrease of strawberry during storage. By the end of 7 days' storage, the hardness, contents of organic acid, soluble solids, and reducing sugar of coated strawberries were increased by 35.1%, 38.5%, 14.1%, and 3.5%, respectively, compared to the control group; and the decay rate of strawberries in CMCHS/OCMC group also dropped to 36%, about 42% decrease than that in control, suggesting the promising application of CMCHS/OCMC composite in coating preservation.

“…Penicillium is widely distributed in various habitats, including soil, plants, air, and indoor settings, and various types of foods Houbraken and Samson, 2011;Visagie et al, 2014a). Penicillium fungi, such as P. rubens for penicillin production, P. citrinum for synthesizing cholesterol-lowering drug mevastatin, P. camemberti and P. roqueforti for cheese production, and P. oxalicum with biocontrol potential, have significant economic value in antibiotic production, pharmaceutical synthesis, biocontrol, food processing, and food safety (Giraud et al, 2010;Houbraken et al, 2011a;Tsang et al, 2018;Steenwyk et al, 2019;Dumas et al, 2020;Yang et al, 2022). In addition, Penicillium can have some negative effects in some cases, such as producing a variety of mycotoxins that can cause food contamination and even threaten human health Perrone and Susca, 2017;Stefanello et al, 2022).…”

IntroductionPenicillium species exhibit a broad distribution in nature and play a crucial role in human and ecological environments.MethodsTwo Penicillium species isolated from the ancient Great Wall loess in the Mentougou District of Beijing, China, were identified and described as new species, namely, Penicillium acidogenicum and P. floccosum, based on morphological characteristics and phylogenetic analyses of multiple genes including ITS, BenA, CaM, and RPB2 genes.ResultsPhylogenetic analyses showed that both novel species formed a distinctive lineage and that they were most closely related to P. chrzaszczii and P. osmophilum, respectively.DiscussionPenicillium acidogenicum is characterized by biverticillate conidiophores that produce globose conidia and is distinguished from similar species by its capacity to grow on CYA at 30°C. Penicillium floccosum is typically recognized by its restricted growth and floccose colony texture. The description of these two new species provided additional knowledge and new insights into the ecology and distribution of Penicillium.
