“…Several protocols have been used to evaluate antimicrobial potential of endophytic actinomycetes. Methods such as cross streak technique and dual inoculation are used for preliminarily screening for antimicrobial potential of actinomycetes (Gayathri and Muralikrishnan, 2013;Kandpal et al, 2013;Phuakjaiphaeo and Kunasakdakul, 2015;Passari et al, 2015;Rao et al, 2015).…”

Endophytes are organisms that are intimately associated with various parts of plants. Endophytic actinomycetes represent actinomycetes of various genera that are associated with various parts of the plants. The beneficial interactions of endophytic actinomycetes with plants are being considered as an important area of research. These endophytic actinomycetes are an attractive source of novel bioactive compounds having pharmaceutical and agricultural importance. Endophytic actinomycetes are associated with different parts such as roots, stem and leaves. Their isolation requires the selection of plant parts and their surface sterilization so as to remove adhering dirt and organisms. A range of surface sterilants such as ethanol, sodium hypochlorite, sodium thiosulfate and sodium carbonate are used for this purpose. Media such as potato dextrose agar, yeast extract-malt extract agar, actinomycetes isolation agar and starch casein agar are used for isolation of actinomycetes. Identification of isolated endophytic actinomycetes is usually based on cultural, microscopic, staining, biochemical and genetic studies. The antimicrobial potential of endophytic actinomycetes is tested by primary as well as secondary screening procedures. Methods such as cross streak and dual inoculation method are used in primary screening. Disk diffusion and well diffusion techniques are commonly employed for secondary screening. Crude extracts and purified compounds from endophytic actinomycetes are shown to exhibit a range of bioactivities such as antimicrobial, antiviral, antioxidant and anticancer activity. Among these, antimicrobial potential of endophytic actinomycetes appears to be an important one. Several researchers have worked on isolation and antimicrobial activity of endophytic actinomycetes isolated from different parts of various plants. It is found that endophytic actinomycetes exhibit inhibitory activity against Gram positive bacteria, Gram negative bacteria, yeasts and filamentous fungi. The isolates and their metabolites are shown to exert detrimental effect against drug resistant pathogens such as methicillin resistant Staphylococcus aureus (MRSA) and penicillin resistant S. aureus. Many isolates are effective against phytopathogenic fungi. These endophytic actinomycetes appear promising resources of bioactive agents and hence, they can be exploited for protection of crops and production of therapeutic agents active against disease causing agents.

Highlights Endophytes act as chemical synthesizers of the secondary metabolites of the host plant. Endophytic microflora has been isolated from a wide array of plants. It can serve as a good alternative source for pharmaceutically important compounds. The arid ecosystem of Thar Desert is a rich repository of ethnomedicinal plants. Role of endophytes in the synthesis of bioactive molecules used to enhance production.

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.
