The diversity and beneficial characteristics of endophytic microorganisms have been studied in Plectranthus tenuiflorus medicinal plant. However, information regarding naturally occurring P. tenuiflorus plant associated endophytes among different organs of host is limited. Endophytic bacteria were isolated from root, stem, and leaves of P. tenuiflorus plant. Among 28 endophytic bacterial isolates from different organs of P. tenuiflorus plant, 8 isolates were identified by partial sequencing of their 16S rRNA gene. The isolated endophytic bacteria were Bacillus sp., Bacillus megaterium, Bacillus pumilus, Bacillus licheniformis, Micrococcus luteus, Paenibacillus sp., Pseudomonas sp., and Acinetobacter calcoaceticus. The most isolates that exhibited extracellular enzymatic activity were belonged to the genus Bacillus. Furthermore, Bacillus sp. (HE613660) exhibited the stronger activities in extracellular enzymes such as amylase, esterase, lipase, protease, pectinase, xylanase, and cellulase than other strains. Considerable antimicrobial activities against a panel of human pathogenic microorganisms (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Streptococcus agalactiae, Proteus mirabilis, and Candida albicans) were recorded using crude extracts of the collected endophytic strains.

“…In this, endophytic fungi are relatively unexplored area among microbe isolation and it represents a new source for retrieving the enzymes with different potentialities. 1 Theendophytic fungi on medicinal plant are proposed to have unique and extreme habitats possessing novel metabolic and enzyme systems which may help for the host protection and colonization. Furthermore, the endophytes are the economical sources in discovering the novel enzymes for medical purposes and this interest has been drawn after the discovery of taxol which is an anticancer drug used in medicinal fields.…”

Fungal species expands an endophytic role inside the tissues of medicinal plants and are known to produce metabolites, phytochemicals and enzymes in a wide range with biological properties. In the present investigation, the most dominant and potent endophytic fungal strains of Aeglemarmelos, an ethno medicinal plant prevalent in the forest of Western Ghats, Tamil Nadu, India were screened for ability to produce exoenzymes like amylase, protease, lipase, cellulase, laccase and xylanase. The representative potent strains were Curvulariaaustraliensis(FC2AP)and Alternariacitrimacularis(FC8ABr) belonged to the same order Pleosporales. The growth of the endophytic fungi was similar with the highest mycelia formation in the respective media. These endophytic fungal strains produced extracellular enzymes in different pH at different incubation period in a considerable range. Furthermore, the endophytes produced phytochemicals constituents flavonoids and phenols, and this unveils that the strains have highest antioxidant properties. The production of enzymes and phytochemicals provided the insights into their origin and ecological role in the host plant. Hence, this study explains the production and biological activity of enzymes and phytochemicals in endophytic fungi.

“…The EI has been used a fast tool for selecting and comparing the enzyme production among different bacterial isolates (Carrim et al, 2006;Castro et al, 2014). Fungaro and Maccheroni (2002) suggested that EI greater than 1.0 are a reliable indicator for the presence of enzymes excreted by microorganisms, while EI ≥ 2.0 is considered good indicator for potential enzyme production by a bacterium (Lealem and Gashe, 1994).…”

ABSTRACT. Secondary metabolites produced by Actinobacteria of tropical soils represent a largely understudied source of novel molecules with relevant application in medicine, pharmaceutical and food industries, agriculture, and environmental bioremediation. The present study aimed to characterize sixty-nine Actinobacteria isolated from compost and tropical soils using morphological, biochemical, and molecular methods. All the isolates showed high variation for morphological traits considering the color of pigments of the aerial and vegetative mycelium and spore chain morphology. The enzymatic activity of amylase, cellulase, and lipase was highly variable. The amylase activity was detected in 53 (76.81%) isolates. Eighteen isolates showed enzymatic index (EI) > 4.0, and the isolates ACJ 45 (Streptomyces curacoi) and ACSL 6 (S. hygroscopicus) showed the highest EI values (6.44 and 6.42, respectively). The cellulase activity varied significantly (P ≤ 0.05) among the isolates. Twenty-nine isolates (42.02%) showed high cellulase activity, and the isolates ACJ 48 (S. chiangmaiensis) and ACJ 53 (S. cyslabdanicus) showed the highest EI values (6.56 for both isolates). The lipase activity varied statistically (P ≤ 0.05) with fourteen isolates (20.29%) considered good lipase producers (EI > 2.0). The isolate ACSL 6 (S. hygroscopicus) showed the highest EI value of 2.60. Molecular analysis of partial 16S rRNA gene sequencing revealed the existence of 49 species, being 38 species with only one representative member and 11 species represented by one or more strains. All species belonged to three genera, namely Streptomyces (82.61%), Amycolatopsis (7.25%), and Kitasatospora (10.14%). The present results showed the high biotechnological potential of different Actinobacteria from tropical soils.
