Endophytic fungi have been in the spotlight as a reservoir of novel agents with diverse bioactivities. Similarity in chemical diversity with the host plant makes them an amenable target for industrial interventions. A wide range of compounds as secondary metabolites and enzymes are manufactured inside the endophytic fungal factory. However, utilization of endophytic fungi as industrially imperative enzyme producers has been a scarce event. The present study was conducted to bio-prospect the fungal endophytes present in the high altitude medicinal plants of Uttarakhand, as industrially imperative enzyme producers. A total of 58 different endophytic isolates were obtained from Pinus sabiniana, Cinnamomum tamala, Cinnamomum verum, Ocimum tenuiflorum and Rhododendron arboreum. Endophytic fungal colonization was highest, 31%, in Pinus sabiniana. The pure isolates were further explored for the production of amylases, cellulases, proteases and L-asparaginase. Out of 58 isolates, 40 isolates exhibited potent enzyme productivity. #7PSSTB isolate was considered as superlative contender on account of its relatively higher production of all the three enzymes viz. amylases, cellulases, proteases. Partial purification of #7PSSTB extract showed compelling enzymatic activity corroborating the existence of exogenous enzyme in the extract. Interestingly, #9 RASTB, #11 RASTB and #17 RASTB exhibited the production of therapeutically imperative L-asparaginase enzyme. The present study puts the spotlight on endophytic diversity in the high altitude medicinal plants as a source of enzymes of industrial interest. Production of L-asparaginase paves the way of pharmaceutical intervention to explore anti-oncogenic effects in the endophytic fungal repository of high altitude regions.

“…Penicillium sp. was also reported to be efficacious against plant pathogenic fungi [50] and, interestingly, P. minioluteum attracted more attention for its beneficial effects on plant stress tolerance [51]. The growth inhibitory activity against plant pathogenic fungi by these endophytes indicates that endophytic fungi have the potential to be used as biocontrol agents in the future.…”

Endophytes are important components of forest ecosystems, and have potential use in the development of medical drugs and the conservation of wild medicinal plants. This study aimed to examine the diversity and antimicrobial activities of endophytic fungi from a medicinal plant, Litsea cubeba (Lour.) Pers. The results showed that a total of 970 isolates were obtained from root, stem, leaf, and fruit segments of L. cubeba. All the fungal endophytes belonged to the phylum Ascomycota and could be classified into three taxonomic classes, nine orders, twelve families, and seventeen genera. SF15 (Colletotrichum boninense) was the dominant species in L. cubeba. Leaves harbored a greater number of fungal endophytes but lower diversity, while roots harbored the maximum species diversity of endophytic fungi. For the antimicrobial activities, seventeen isolates could inhibit the growth of plant pathogenic fungi, while the extracts of six endophytes showed antimicrobial activity to all the tested pathogenic fungi. Among these endophytes, SF22 (Chaetomium globosum) and SF14 (Penicillium minioluteum) were particularly effective in inhibiting seven plant pathogenic fungi growths and could be further explored for their potential use in biotechnology, medicine, and agriculture.

“…Endophytic fungi are highly diverse, and more than 1 million species of this fungal group is estimated to be undiscovered (Sun and Guo 2012). They represent an important component of fungal biodiversity and it has also been observed that almost every plant examined to date harbors at least one species of endophytic fungi, while many plants, particularly woody plants, contain hundreds of endophytic species (Petrini 1986;Sahoo et al 2017). However, various factors affect the distribution of the endophytic fungal community, such as environmental factors (temperature, humidity), and the type and age of the colonized host tissue (Sanchez-Azofeifa et al 2012).…”

Bioprospecting and biodiversity investigations of endophytic fungi isolated from Juniperus communis

et al. 2021

Endophytes are a group of highly diverse microorganisms that reside within plant tissues without causing obvious symptoms on the host. In our study, Juniperus communis samples were collected from Hungary and used for the isolation of endophytic fungal strains. From 240 plant samples, 76 fungal isolates were recovered and subcultured for homogeneity. The isolates were identified using molecular taxonomical tools at the genus level and their biodiversity parameters were determined. The taxonomic diversity of the isolates was remarkably high, and the most abundant genera were Fusarium, Alternaria and Trichoderma. The secondary metabolites produced by the isolated endophytic fungi were extracted both from their mycelia and their ferment broth and their antimicrobial activities were tested against bacteria, yeasts, and filamentous fungi. In the antimicrobial tests, a total of 58 strains showed antimicrobial activity against at least one test organism. Altogether, 6.67% of the isolates have antibacterial effects with wide spectrum, and 10 strains showed remarkably high inhibitory percentage against yeast, while the extracts of 11 isolates proved to be active against filamentous fungi.
