Abstract

Aloe verais among the world’s economically most important medicinal plants, but as the growth of this plant and, consequently, the accumulation of metabolites is slow, we tested the hypothesis that root endophytic bacteria isolated from A. veraplants can promote growth and increase the accumulation of aloin in the gel and latex. For this, we inoculate seedlings with four endophytic bacteria and a combination of them. We confirmed the hypothesis and identified two strains with potential for the formulation of inoculants to improve the cultivation of A. vera. The bacterium 149H Paraburkholderiasp. increases the number of leaves and the accumulation of biomass, but on the other hand, 35V Enterobacter ludwigiiinoculation increased the content of aloin in the gel and in the latex. Further research should focus on the association of these two strains in a single inoculant, to both promote growth and increase the synthesis of metabolites.

内生细菌促进芦荟生长，增加芦荟素含量

芦荟是世界上经济上最重要的药用植物之一，但由于芦荟的生长和代谢产物的积累较慢，我们检验了从芦荟中分离出的根内生细菌可以促进芦荟生长和增加凝胶和乳胶中芦荟素的积累的假设。为此，我们用四种内生细菌及其组合接种幼苗。我们证实了这一假设，并鉴定出两株有潜力配制接种剂以改善真丝芽孢杆菌的培养。细菌149H paraburkholderasp。另一方面，接种35V路德维希肠杆菌增加了凝胶和乳胶中芦荟素的含量。进一步的研究应该关注这两种菌株在单一接种剂中的关联，既促进生长又增加代谢物的合成。

期刊介绍： The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
