“…The plant has a pleasant aroma similar to the commercial product 'Vicks.' In Taif, it is used as an eardrop for earache and inflammation of middle ear (Chandrasekaran and Venkatesalu 2004), whereas it is prescribed in Asia for a reedy sore throat (Rahman et al 2004). Few studies have been conducted on the chemotype and activity of the essential oils from different species of Plectranthus.…”

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.

“…Native to India, Ceylon, Malaysia and Australia (1), it has been widely grown as an ornamental plant, mainly along the coast, and it can be found in several Brazilian states such as Minas Gerais, Rio de Janeiro and São Paulo (2). Several studies have determined the presence of hydrolysable tannins in the plant, particularly in the seeds, increasing the chance of obtaining endophytic microorganisms that (3)(4)(5).…”

SummaryTannase (EC 3.1.1.20) is an enzyme that hydrolyzes the ester and depside bonds of tannic acid to gallic acid and glucose. In the production of foods and beverages, it contributes to the removal of the undesirable eff ects of tannins. The aim of this study is to investigate the potential of endophytic fungi isolated from jamun (Syzygium cumini (L.) Skeels) leaves, and identifi ed as Pestalotiopsis guepinii, in the production of tannase. Tannase was produced extracellularly by P. guepinii under submerged, slurry-state and solid-state fermentations. The submerged fermentation was found to be the most promising (98.6 U/mL). Response surface methodology was employed to evaluate the eff ect of variables (pH and temperature), and the results showed that the best conditions for tannase activity were pH=6.9 and 30 °C. K m was found to be 7.18·10 -4 mol/L and v max =250.00 U/mL. The tannase activity was the highest in the presence of Ca 2+ at a concentration of 5·10 -3 mol/L. Moreover, the enzyme was not inhibited by the tested chelators and detergents. The stability of the enzyme was also studied, and crude enzyme was evaluated in simulation of gastrointestinal digestion of monogastric animals. The crude enzyme was highly stable under simulated conditions; it retained 87.3 % of its original activity a er 6 h. The study contributes to the identifi cation of microbial species that produce tannase, with potential application in biotechnology.
