The ecosystem is considerably affected due to the extensive use of chemical pesticides and fertilizers. As an alternative strategy, this study aimed assess biocontrol potential bioagents arbuscular mycorrhizal fungi plant growth-promoting Trichoderma harzianum MZ025966 against tomato root-knot nematodes (Meloidogyne javanica). T. showed a great potentiality produce indole acetic acid (IAA) (12.11 ± 2.12 μg/mL) exhibited noticeable activity ammonification. Furthermore, revealed protease...
Effective biosafe management strategies are used to decrease world crop damage produced by plant-parasitic nematodes. This study evaluated the efficiency of hydroxyapatite nanoparticles (n-HAP) and mycorrhizal fungi control Meloidogyne incognita infecting tomato plants. Application n-HAP significantly increased juveniles’ mortality (195.67%) egg hatching inhibition percentage (80.71%) compared untreated control, in vitro. Mycorrhizal and/or treatments plant growth parameters (root shoot...
Recently, there have been urgent economic and scientific demands to decrease the use of chemical fungicides during treatment phytopathogens, due their human health environmental impacts. This study explored biocontrol efficacy novel eco-friendly preen (uropygial) oil endophytic
Abstract In this study, two highly thermotolerant and methanol-tolerant lipase-producing bacteria were isolated from cooking oil they exhibited a high number of catalytic lipase activities recording 18.65 ± 0.68 U/mL 13.14 0.03 U/mL, respectively. Bacterial isolates identified according to phenotypic genotypic 16S rRNA characterization as Kocuria flava ASU5 (MT919305) Bacillus circulans ASU11 (MT919306). Lipases produced showed the highest methanol tolerance, 98.4% relative activity well...
Abstract A reduction in crop spoilage and an increase shelf-life is the goal of effective disease control methods. This study aimed to assess ZnO-nanoparticles (ZnO-NPs) as a safe, new protectant against Rhizopus soft rot sweet potato. ZnO-NPs had fungicidal effect stolonifer when used at concentrations above 50 ppm. The results showed that tubers treated with exhibited fewer fungal populations (1.2 CFU per segment) than those did not receive treatment. Tubers infected no visible decay for...
Botrytis umbel blight caused by allii is a major disease that attacks onion crop. In vitro, Trichoderma viride, Penicillium chrysogenum, and Saccharomyces cerevisiae extract of bitter apple fruits (Citrullus colocynthis) showed antagonistic effect inhibited the mycelial growth B. allii. Gas chromatography–mass spectrometry (GC-MS) analysis existence 37 compounds their derivatives. Among them, 10 constituted 58.66% total analyses. Greenhouse experiment approved was most effective in reducing...
This study demonstrated a biotechnological approach for simultaneous production of low-cost H2, liquid biofuels, and polyhydroxyalkanoates (PHAs) by solventogenic bacterium (Clostridium beijerinckii) from renewable industrial wastes such as molasses crude glycerol. C beijerinckii ASU10 (KF372577) exhibited considerable performance hydrogen 5.1 ± 0.84 11 0.44 mL H2 h−1 on glycerol sugarcane molasses, respectively. The total acetone-butanol-ethanol (ABE) generation was 9.334 2.98 10.831 4.1 g...
The increasing global demand for petroleum oils has led to a significant increase in their cost and the search renewable alternative waste resources biodiesel synthesis production using novel environmentally sound acceptable methods. In current study, Kocuria flava lipase was immobilized on Fe3O4/cellulose nanocomposite; used as biocatalyst conversion of cooking oil wastes into through transesterification/esterification process. characterization nanocomposite revealed several functional...
Potato peel wastes are generated in high quantities from potato processing industries. They pollutants to the environment, and they release greenhouse gases into atmosphere. The present study assessed potentiality of hydrolyzing by amylase-producing fungi improve biogas generation peels through anaerobic digestion process. Different fungal isolates were screened for amylase production on wastes, highest producer was selected optimizing efficacy producing amylases efficiently allow conversion...
Toxigenic fungi (Aspergillus and Fusarium) their metabolites represent the major cause of corn corn-based products contamination consequently lead to severe economic health issues.Our current study aimed investigate efficacy using L. macroides Bac6 as a biological control agent against toxigenic fungi; A. flavus f10 F. proliferatum f30 mycotoxins.The results illustrated that produced aflatoxins AFB1 AFG2 with concentrations 21.239 13.593 ppb, respectively. While fumonisin B1 (9600 ppb)....
In this study, an antagonistic yeast isolate, Wickerhamiella versatilis was considered as a promising biocontrol agent against Pectobacterium carotovorum subsp. Carotovorum (Pcc) the causal of soft rot disease potato. Antagonistic inhibited growth Pcc in vitro, and reducing severity infected potato tubers (cv. Diamant) under greenhouse conditions. Consequently, cellulase pectinase hydrolytic activities with + were decreased compared Pcc. The histological characterization treated W. using...
