The Extracts of Cinnamon and Clove as Potential Biofungicides against Strawberry Grey Mould.

ABSTRACT: Biofungicides from plants are a possibility for the biocontrol of fungal diseases, as chemical products may be harmful to the environment and humans. Strawberry is one of the many plants infected by grey mould (Botrytis cinerea), and innovative methods of biocontrol against B. cinerea are under investigation. Clove (Syzygium aromaticum L.) and cinnamon (Cinnamomum cassia L.) accumulate natural compounds, such as eugenol and cinnamaldehyde, which provide antimicrobial and antifungal properties; thus, extracts of these plants could be possibly used as biofungicides. During this study, the inhibition of B. cinerea by clove and cinnamon extracts was evaluated in vitro on Petri plates and detached strawberry leaves; additionally, the chemical composition of volatiles was identified. Clove extract consisted of 52.88% eugenol, and cinnamon consisted of 74.67% cinnamaldehyde. The efficacy of the extracts on detached strawberry leaves showed that 12 mL L-1 concentration of clove extract was effective in suppressing the grey mould infection. Clove and cinnamon extracts showed an equal ability to inhibit B. cinerea on Petri plates. However, the results of the detached strawberry leaves assay showed that clove extract was more effective as a biocontrol product. Overall, clove extract expressed a high potential for application in biofungicides formulations.

Project description:Encapsulated phytochemicals with augmented therapeutic and nutritional characteristics have become promising alternatives to antimicrobials in the poultry industry. Hence, our key target was to explore the efficacy of liposomal encapsulation, as a novel carrier, for essential oils (LEOs) on growth, digestibility, intestinal microbiota, and bacterial metabolites of broiler chickens. Moreover, the impact of encapsulated EOs on transcription mechanisms targeting the genes encoding digestive enzymes, gut barrier functions and antioxidant potential of broiler chickens was evidenced. Four equal broiler groups were fed 4 basal diets fortified with LEOs (oregano, cinnamon, and clove) at the levels of 0, 200, 300, and 400 mg/kg diet. Our findings revealed significant improvement in body weight gain and feed conversion ratio of birds fed higher levels of LEOs. These results came concurrently with increasing the activities of digestive enzymes at both serum and molecular levels and consequently nutrient digestibility (dry matter, ether extract, crude protein, and crude fiber) in these groups. Remarkably, the abundance of beneficial bacteria as well as the bacterial metabolites (valeric acid, butyric acid, propionic acid, acetic acid, and total short-chain fatty acids) was increased, while that of pathogenic ones was reduced following dietary inclusion of LEOs. Of note, the mRNA expression of genes encoding antioxidant stability [catalase (CAT), superoxide dismutase 1 (SOD-1), glutathione peroxidase 1 (GPX-1), nuclear factor erythroid 2-related factor 2 (NRF2), NAD(P)H dehydrogenase quinone 1 (NQO1), and heme oxygenase-1 (HO-1)] as well as barrier functions [mucin-2 (MUC-2)] and tight junction proteins, TJP [junctional adhesion molecule-2 (JAM-2) and occludin] were noticeably upregulated in broilers fortified with 400 mg/kg diet of LEOs. Overall, the present work recommended dietary inclusion of LEOs as beneficial additives for attaining targeted performance, gut health and antioxidant stability in poultry farming.

Project description:Early detection of pathogenic fungi in controlled environment areas can prevent major food production losses. Grey mould caused by Botrytis cinerea is often detected as an infection on lettuce. This paper explores the use of vegetation indices for early detection and monitoring of grey mould on lettuce under different lighting conditions in controlled environment chambers. The aim was focused on the potential of using vegetation indices for the early detection of grey mould and on evaluating their changes during disease development in lettuce grown under different lighting conditions. The experiment took place in controlled environment chambers, where day/night temperatures were 21 ± 2/17 ± 2 °C, a 16 h photoperiod was established, and relative humidity was 70 ± 10% under different lighting conditions: high-pressure sodium (HPS) and light-emitting diode (LED) lamps. Lettuces were inoculated by 7-day-old fungus Botrytis cinerea isolate at the BBCH 21. As a control, non-inoculated lettuces were grown under HPS and LEDs (non-inoculated). Then, the following were evaluated: Anthocyanin Reflectance Index 2 (ARI2); Carotenoid Reflectance Index 2 (CRI2); Structure Intensive Pigment Index (SIPI); Flavanol Reflectance Index (FRI); Greenness (G); Greenness 2 (G2); Redness (R); Blue (B); Blue Green Index 2 (BGI2); Browning Index 2 (BRI2); Lichtenthaler Index 1 (LIC1); Pigment Specific Simple Ratio (PSSRa and PSSRb); Gitelson and Merzlyak (GM1 and GM2); Zarco Tejada-Miller Index (ZMI); Normalized Difference Vegetation Index (NDVI); Simple Ratio (SR); Red-Eye Vegetation Stress Index (RVSI); Photochemical Reflectance Index (PRI); Photochemical Reflectance Index 515 (PRI515); Water Band Index (WBI); specific disease index for individual study (fD); Healthy Index (HI); Plant Senescence Reflectance (PSRI); Vogelmann Red Edge Index (VREI1); Red Edge Normalized Difference Vegetation Index (RENDVI); and Modified Red Edge Simple Ratio (MRESRI). Our results showed that the PSRI and fD vegetation indices significantly detected grey mould on lettuce grown under both lighting systems (HPS and LEDs) the day after inoculation. The results conclusively affirmed that NDVI, PSRI, HI, fD, WBI, RVSI, PRI, PRI515, CRI2, SIPI, chlorophyll index PSSRb, and coloration index B were identified as the best indicators for Botrytis cinerea infection on green-leaf lettuce (Lactuca sativa L. cv Little Gem) at the early stage of inoculated lettuce's antioxidative response against grey mould with a significant increase in chlorophyll indices.
