Unorganized natural nutrient cycle and depleted soil health may prove major limitation on the growth and development of medicinal plants and therefore quality and final yield of the cultivation. Therefore, studies concerned with the restoration of normal fertility to the soil and make it rich with certain nutrients are of the fundamental interest for medicinal plants. Herein, the present study was designed to investigate the multifaceted beneficial effects of (a) Phosphate solubilizing bacteria (Pseudomonas fluorescens) (b) Nitrogen-fixing bacteria (Azotobacter chroococcum) and (c) Mycorrhiza (Sebacina vermifera) on plant growth and seed essential oil composition of ajwain (Trachyspermum ammi). In this context, ajwain fruits were treated with selected biofertilizers to analyze the emergence pattern and to evaluate comprehensive growth and essential oil composition. About 25 days old seedlings were treated with selected biofertilizers. The results showed that all treatments had a good effect on seed emergence, though Sebacina vermifera assisted growth and essential oil production were much higher than other treatments. Concerning the composition, 13 compounds were identified using gas-chromatography. Major altered components were thymol, p-cymene and ϒ-terpinene. It is worthy to mention that each treatment proved to increase thymol only. The enhanced synthesis of thymol is supported by the speculation that biofertilizers may trigger an early or late step expression in biosynthetic pathway that leads higher production of thymol. As a conclusion, biofertilizers can alter the comprehensive growth including essential oil composition of ajwain, and also the chemical composition of ajwain was found to be strongly altered. Along with the study, Sebacina vermifera based biofertilizer indicated immense potentials to be utilize as multifaceted beneficial alternate for sustainable agronomical and medicinal plants productions.

A greenhouse and field experiment was conducted to investigate the effects of Azotobacter (Azotobacter chroococcum), Phosphate solubilizing bacteria (Pseudomonas fluorescens), and Arbuscular mycorrhiza-like fungi (Sebacinca vermifera) on seed germination, physiology, and essential oil production of dill (Anethum graveolens). The experimentation was comprised of a randomized complete block design with six replicates of each treatment. Evaluation of germination was done using parameters; germination percentage, mean germination time, germination index, T 50 of germination, seedling vigour, and vigour index. Physiological responses include the parameters for total length, total fresh weight, and total dry weight of the plant. For physiological evaluation, harvesting of plants was done a total of four times at an interval of 30 days i.e. on 30, 60, 90, 120 days after transplantation. Essential oil analysis was done by hydrodistillation followed by Gas chromatography-Mass spectrometry. All the data collected were statistically analyzed using the GraphPad Prism v6 software package. Results showed that all treatments negatively affected the emergence behavior of seeds, whereas physiology of plants and essential oil production by Sebacina vermifera were significantly higher than other treatments. More specific to essential oil, treatments not only affected the total yield of essential oil but also affected the most components of essential oil. This study is potentially representing an alternative way of promoting the growth and biosynthesis of essential oils in dill.
... S. vermifera enhanced the major chemical components including monoterpene alcohol (linalool) and monoterpene hydrocarbon (α-pinene and β-pinene) of coriander seeds. 12 In general, pure culture of arbuscular mycorrhizal fungi (AMF) not cultivable outside the host, but S. vermifera is a potential AM-like fungi which is cultivable under lab conditions. 13 AMF colonized plants may show increased biomass, faster growth rate & maturity, resistance to biotic and abiotic stresses, and more effective photosynthesis, enhanced yield and better composition of EO. [14][15] Mycorrhizal colonization influences the plant growth and alters the level of secondary metabolites which may depend on extent of root colonization by AMF. ...

Sustainable plant production with the integration of eco-friendly agricultural practices, low chemical inputs, minimal deleterious effects on human health and low cost methods, is the need of the moment. In this direction, scientific/industrial community, continuously exploring novel and reliable methods. Plant growth promoting microbes are proving more promising to achieve eco-friendly and sustainable agricultural outcomes. In the present study, individuals of Foeniculum vulgare, a valuable aromatic plant species with potential medicinal value, were inoculated with different plant growth promoting microorganisms: (1) Arbuscular mycorrhizal like fungi (Sebacina vermifera) (2) Phosphate solubilizing bacteria (Pseudomonas fluorescens) (3) Azotobacter (Azotobacter chroococcum). Response of individual microorganism species was evaluated with reference to the emergence, plant growth and yield of essential oil along with qualitative effects on essential oil. Comparatively, significant response of Sebacina vermifera, in the stimulation of emergence of seeds, growth of plant and yield enhancement of essential oil was observed. An enhanced synthesis of anethole (major chemical constituent) was also recorded. Moreover, the enhancement in growth of plants was dependent on the extent of colonization percentage. A periodic study of growth parameters indicates plant’s health and vitality influenced by Sebacina vermifera. The enhanced essential oil of seeds along with enhanced synthesis of anethole was in agreement with the assumption that Sebacina vermifera trigger defensive responses and hence improve phytochemical production. A mechanistic insight is also illustrated. In conclusion Sebacina vermifera possesses immense potentials in the pursuit of agro-ecological attributes of medicinal plant cultivation and crop production. It exerts excellent growth effects and enhances phytochemical production in medicinal plants.
