Plant Growth-Promoting Activities of Bacteria Isolated from an Anthropogenic Soil Located in Agrigento Province
2022
Bacteria producers of plant growth-promoting (PGP) substances are responsible for the enhancement of plant development through several mechanisms. The purpose of the present work was to evaluate the PGP traits of 63 bacterial strains that were isolated from an anthropogenic soil, and obtained by modification of vertisols in the Sicily region (Italy) seven years after creation. The microorganisms were tested for the following PGP characteristics: indole acetic acid (IAA), NH3, HCN and siderophore production, 1-aminocyclopropane-1-carboxylate deaminase activity (ACC) and phosphate solubilization. The results of principal component analysis (PCA) showed that Bacillus tequilensis SI 319, Brevib…
Biologically active compounds in algae and their application in plant growth stimulation
2016
In recent years the bioactive substances of natural origin gained more and more interest. Among such substances, the compounds isolated from microalgae and seaweeds, mainly the polyphenols, polysaccharides, plant hormones, pigments and fatty acids, an find an application in many industries, particularly in medicine, pharmaceutics, cosmetics and agriculture. Biostimulants from seaweeds have been used and manufactured for years, giving confirmation of its effectiveness in field trials, enhancing the growth of crops giving better yields. Nowadays, the legislation processes are more difficult and intricate, so it is harder to register new products. Everyone put more attention on the answers for…
