“…Concerning the statement, compounds found in endophytic fungi may have distinctive mechanisms and perplexing bio-activities, comprising a high proportion offering enormous opportunity for a research study. A research study reveals that endophytic fungi isolated in leaves of Euphorbia hirta showed a broad spectrum of antimicrobial activity against human pathogens [23]. Due to the fungal endophytes' antimicrobial activity, researchers utilize endophytic fungi isolated from the Cocos nucifera cotyledon to observed potential antibacterial and antifungal activity.…”

The study aimed to evaluate the endophytic fungi isolated from Cocos nucifera (L.) cotyledon for their possible antimicrobial activity. A total of twelve endophytic fungal species were successfully isolated, from which five were selected and presumptively identified, including Aspergillus niger, Raffaelea sp., Aspergillus flavus, Cladosporium sp. and Pseudallescheria spp. based on their macro and microscopic characters. The agar blocks of actively growing pure culture were assessed for antibacterial activity against five human pathogenic bacterial and fungal strains: Escherichia coli (BIOTECH 1634), Bacillus subtilis (BIOTECH 1697), Staphylococcus aureus (BIOTECH 1592), Serratia marcescens (BIOTECH 1748), and Candida tropicalis (BIOTECH 2085). Among the selected five endophytic used for antimicrobial activity screening, the Raffaelea sp. (CN-EF 2) has shown a high zone of inhibition of 11 mm against Bacillus subtilis, 18 mm against Escherichia coli, 15 mm against Staphylococcus aureus, and 11 mm against Candida tropicalis. Correspondingly, Aspergillus niger (CN-EF 1) has shown a zone of inhibition of 16 mm against C. tropicalis. The endophytic fungus Raffaelea sp. was effective against all test organisms except for Serratia marcescens, while Aspergillus niger was only effective for pathogenic fungi C. albicans. Hence, further in-depth studies of the isolated endophytic fungi are needed to determine the mechanisms behind the endophytes' inhibitory effects.

“…Another E. milli fungal endophyte, Chaetomium ovatoascomatis, shows antimicrobial efficacy [38] and a few laccase-producing fungal endophytes are also known [39]. Other than this, from E. hirta, few antimicrobial endophytes [40,41], an antioxidant-producing fungus Nigrospora sphaerica (EHL2) [42,43], and a hepatoprotective Archaetomium sp. are reported [44].…”

Euphorbiaceae is a highly diverse family of plants ranging from trees to ground-dwelling minute plants. Many of these have multi-faceted attributes like ornamental, medicinal, industrial, and food-relevant values. In addition, they have been regarded as keystone resources for investigating plant-specific resilience mechanisms that grant them the dexterity to withstand harsh climates. In the present study, we isolated two co-culturable bacterial endophytes, EP1-AS and EP1-BM, from the stem internodal segments of the prostate spurge, Euphorbia prostrata, a plant member of the succulent family Euphorbiaceae. We characterized them using morphological, biochemical, and molecular techniques which revealed them as novel strains of Enterobacteriaceae, Lelliotia amnigena. Both the isolates significantly were qualified during the assaying of their plant growth promotion potentials. BM formed fast-growing swarms while AS showed growth as rounded colonies over nutrient agar. We validated the PGP effects of AS and BM isolates through in vitro and ex vitro seed-priming treatments with wheat and tomato, both of which resulted in significantly enhanced seed germination and morphometric and physiological plant growth profiles. In extended field trials, both AS and BM could remarkably also exhibit productive yields in wheat grain and tomato fruit harvests. This is probably the first-ever study in the context of PGPB endophytes in Euphorbia prostrata. We discuss our results in the context of promising agribiotechnology translations of the endophyte community associated with the otherwise neglected ground-dwelling spurges of Euphorbiaceae.

“…24 Investigations of the endophytic fungal populations of some Nigerian medicinal plants have revealed the enormous potentials possessed by these organisms as sources of compounds of pharmaceutical and industrial importance. [24][25][26][27][28][29][30][31] There is, therefore, the need to further explore these plants for endophytes producing biologically important molecules. Hence, our study seeks to investigate the secondary metabolites of an endophytic fungus isolated from leaves A. muricata growing in Anambra State, South-East Nigeria.…”
