“…It is also a source of antibiotics against multidrug-resistant bacteria [ 110 ] and able to degrade waste [ 111 ]. Finally, S. maltophilia seems to be promising in medical therapy [ 112 , 113 ]. Regarding the nitrogen-fixing rhizobia isolated from root nodules of the trap host legume (i.e., cowpea inoculated with mopane rhizosphere soils), our results suggest that similarly to other African legume trees [ 94 ], Bradyrhizobium is the predominant genus in the rhizosphere of C. mopane .…”

(1) Aims: Assessing bacterial diversity and plant-growth-promoting functions in the rhizosphere of the native African trees Colophospermum mopane and Combretum apiculatum in three landscapes of the Limpopo National Park (Mozambique), subjected to two fire regimes. (2) Methods: Bacterial communities were identified through Illumina Miseq sequencing of the 16S rRNA gene amplicons, followed by culture dependent methods to isolate plant growth-promoting bacteria (PGPB). Plant growth-promoting traits of the cultivable bacterial fraction were further analyzed. To screen for the presence of nitrogen-fixing bacteria, the promiscuous tropical legume Vigna unguiculata was used as a trap host. The taxonomy of all purified isolates was genetically verified by 16S rRNA gene Sanger sequencing. (3) Results: Bacterial community results indicated that fire did not drive major changes in bacterial abundance. However, culture-dependent methods allowed the differentiation of bacterial communities between the sampled sites, which were particularly enriched in Proteobacteria with a wide range of plant-beneficial traits, such as plant protection, plant nutrition, and plant growth. Bradyrhizobium was the most frequent symbiotic bacteria trapped in cowpea nodules coexisting with other endophytic bacteria. (4) Conclusion: Although the global analysis did not show significant differences between landscapes or sites with different fire regimes, probably due to the fast recovery of bacterial communities, the isolation of PGPB suggests that the rhizosphere bacteria are driven by the plant species, soil type, and fire regime, and are potentially associated with a wide range of agricultural, environmental, and industrial applications. Thus, the rhizosphere of African savannah ecosystems seems to be an untapped source of bacterial species and strains that should be further exploited for bio-based solutions.

“…Previous studies have shown that the synthesis of multiple bioactive secondary metabolites, including alkaloids, sesquiterpenes, polyketones, lactones, organic acids, cyclopeptides, flavonoids, and saponins, with novel applications can be accomplished by endophytes present in host plants (Ek-Ramos et al, 2019). Further activity studies revealed that these endophytic bacteria and their host plants share several similar bio-properties such as antimicrobial, anticancer, antiinflammatory and anti-HIV activities (Table 3; Rustamova et al, 2020). Endophytes are extremely crucial biological resources, the exploration of which in the future can facilitate environmental sustainability, and they can act as unlimited biomolecule sources for various industrial sectors and benefiting human health.…”

Plants benefit extensively from endophytic bacteria, which live in host plant tissues exerting no harmful effects. Bacterial endophytes promote the growth of host plants and enhance their resistance toward various pathogens and environmental stresses. They can also regulate the synthesis of secondary metabolites with significant medicinal properties and produce various biological effects. This review summarizes recent studies on the relationships between bacterial endophytes and medicinal plants. Endophytic bacteria have numerous applications in agriculture, medicine, and other industries: improving plant growth, promoting resistance toward both biotic and abiotic stresses, and producing metabolites with medicinal potential. Their distribution and population structure are affected by their host plant’s genetic characteristics and health and by the ecology of the surrounding environment. Understanding bacterial endophytes can help us use them more effectively and apply them to medicinal plants to improve yield and quality.

“…Considering its benefits in the medical field, more research was conducted on V. anthelmintica plant by tracing its endophytic bacteria and fungi. In this case, V. anthelmintica was collected from the Xinjiang Autonomous Forest Region of the People's Republic of China in previous research [39]. Thus, Rustamova et al [39] successfully isolated 25 bacterial stirpes from V. anthelmintica plant tissue, the isolates were identified as M. endophyticus VERA1, B. megaterium VERA2, P. chlororaphis VERA3, P. kilonensis VERA4, S. pavanii VERA5, B. endophyticus VERA6, S. maltophlia VERA7, P. ananatis VERA8, B. atrophaeus VERA5.…”

The habitat of endophytic bacteria in plant tissues making it automatically used by plants to protect themselves against pathogenic bacteria. Endophytic bacteria have been applied in various fields, including agriculture, pharmacy, medicine, and biotechnology. This review was carried out to summarize recent studies focusing on the diversity of endophytic bacteria derived from traditional medicinal plants which have antibacterial activity and extracellular enzymes. This article was prepared and written by referring to literature studies collected from books and online journal publication. The literature review of endophytic bacteria focused on Vernonia anthelmintic, Saurauia scaberrinae, and Ki rinyuh (Chromolaena odorata) plants. The results revealed that endophytic bacteria obtained from Vernonia anthelmintic plant is from Micrococcus, Bacillus, Pseudomonas, Stenotrophomonas, and Pantoea genus which possess the same biological properties as the host plant, producing antibacterial activity. Saurauia scaberrinae plant successfully isolated endophyte fungus Phoma sp. which produces phomodione (4) and cercosporamide. Phomodione (4) exhibit inhibitory activity against S. aureus, P. ultimum, S. sclerotiorum and R. solani. Cercosporamide exhibits inhibitory activity against S. aureus. Endophytic bacteria were also isolated from Ki rinyuh (Chromolaena odorata), including BECB3, BECB 4, BECA 8, BECA 5, BECA 1, and BECA 10 isolates which have extracellular enzyme activities such as β-amylase, α-amylase, cellulase, chitinase, and protease. Understanding endophytic bacteria in medicinal plants can help researchers apply them effectively.
