“…LBUM300 mitigates Clavibacter michiganensis , which causes canker disease in tomatoes by generating antibiotics, namely, hydrogen cyanide (HCN) and 2,4-diacetylphloroglucinol [ 29 ]. In general, Aspergillus spp., nonpathogenic Fusarium spp., Gliocladium spp., Petriella spp., and Trichoderma spp., along with Bacillus spp., Enterobacter spp., Lysobacter spp., Pantoea spp., Pseudomonas spp., and Streptomyces spp., were identified as prime BCAs [ 17 , 35 , 36 ]. Table 2 and Table 3 illustrate the defense mechanisms of fungal and bacterial endophytes against pathogens while Figure 1 depicts the endophytic biocontrol mode of defense mechanisms against pathogens.…”

“…The microbial enzyme is vital in upgrading plant nutrients, decomposing organic matter, and combating biotic stress. Enzymes have remarkable biotechnological benefits in various fields such as industrial, agricultural, pharmaceutical, and biomedical therapy [ 17 ]. Hydrolytic enzymes have an antagonistic property that can inhibit or resist pathogens through the hyper-parasite mechanism and thus have an incredible biocontrol role in crop fertility.…”

“…Endophytes are ubiquitous and reside in the intercellular tissues of about 300,000 plant species without causing any negative impacts [ 16 ]. Some predominant prokaryotic and eukaryotic endophytes that have been explored are Actinobacteria , Ascomycota , Bacteroidetes , Basidiomycota , Firmicutes , Proteobacteria , and Zygomycota [ 17 ]. Endophytes produce several secondary metabolites, enzymes, and hormones that have a vital role in biotechnology.…”

Plants are subjected to multifaceted stresses that significantly jeopardize crop production. Pathogenic microbes influence biotic stress in plants, which ultimately causes annual crop loss worldwide. Although the use of pesticides and fungicides can curb the proliferation of pathogens in plants and enhance crop production, they pollute the environment and cause several health issues in humans and animals. Hence, there is a need for alternative biocontrol agents that offer an eco-friendly mode of controlling plant diseases. This review discusses fungal- and bacterial-induced stress in plants, which causes various plant diseases, and the role of biocontrol defense mechanisms, for example, the production of hydrolytic enzymes, secondary metabolites, and siderophores by stress-tolerant fungi and bacteria to combat plant pathogens. It is observed that beneficial endophytes could sustain crop production and resolve the issues regarding crop yield caused by bacterial and fungal pathogens. The collated literature review indicates that future research is necessary to identify potential biocontrol agents that can minimize the utility of synthetic pesticides and increase the tenable agricultural production.

“…Filamentous fungi are used in many industrial processes to produce secondary bioactive metabolites such as vitamins, polysaccharides and pigments. Yakop et al [27], has reported on the genera of fungi commonly isolated from soil, these included Aspergillus, Penicillium, Trichoderma and Fusarium. In this present study, six genera were obtained which comprised of Penicillium (8%, n = 9), Fusarium (2%, n = 2), Talaromyces (2%, n = 2), Wojnowiciella (0.9%, n = 1), Epicoccum (0.9%, n = 1), Phoma (0.9%, n = 1) and Metarhizium (0.9%, n = 1).…”

The food and pharmaceutical industries are searching for natural colour alternatives as required by consumers. Over the last decades, fungi have emerged as producers of natural pigments. In this paper, five filamentous fungi; Penicillium multicolour, P. canescens, P. herquie, Talaromyces verruculosus and Fusarium solani isolated from soil and producing orange, green, yellow, red and brown pigments, respectively, when cultured on a mixture of green waste and whey were tested. The culture media with varying pH (4.0, 7.0 and 9.0) were incubated at 25 °C for 14 days under submerged and solid-state fermentation conditions. Optimal conditions for pigment production were recorded at pH 7.0 and 9.0 while lower biomass and pigment intensities were observed at pH 4.0. The mycelial biomass and pigment intensities were significantly higher for solid-state fermentation (0.06–2.50 g/L and 3.78–4.00 AU) compared to submerged fermentation (0.220–0.470 g/L and 0.295–3.466 AU). The pigment intensities were corroborated by lower L* values with increasing pH. The λmax values for the pigments were all in the UV region. Finally, this study demonstrated the feasibility of pigment production using green waste:whey cocktails (3:2). For higher biomass and intense pigment production, solid-state fermentation may be a possible strategy for scaling up in manufacturing industries.

“…They are known as the second largest after kingdom Animalia with estimate of over 5 million species (Raja et al, 2017). The kingdom fungi is composed of nine phyla mamely; Opisthosporidia, Chytridiomycota, Neocallimastigomycota, Blastocladiomycota, Zoopagomycota, Mucoromycota, Glomeromycota, Basidiomycota and Ascomycota (Simeos et al, 2015;Yakop et al, 2019). The Ascomycota or sac fungi, are monophyletic and account for approximately 75% of all described fungi.…”

The aim of this study was isolation and molecular characterization of fungi from untreated industrial effluent by multigene phylogenetic analyses. The Fungi isolated were characterized based on PCR amplification and genomic sequencing of the internal transcribed spacer region (ITS), partial β-tubulin (Ben A), calmodulin (CaM), and DNA-directed RNA polymerase second large subunit (RPB2) genes, along with morphological characterization and species diversity. Fungal DNA extraction kits and primers sets for the selected genes were purchased and used following the manufacturer’s instructions. The obtained sequences were subjected to BLAST analysis and the corresponding fungal isolates were assigned species names after comparison with representative sequences available in GenBank. All the sequences from this study were deposited in GenBank and the accession number assigned. Phylogenetic trees of the fungal isolates were drawn for each gene by the Maximum Likelihood method using MEGA 7.0 software. Fifteen (15) Fungi species belonging to four genera of Aspergillus, Penicillium, Fusarium and Trichoderma with Aspergillus as the predominant genus were identified.
