5‐Aminolevulinic Acid: A Potential Herbicide/Insecticide from Microorganisms

Abstract

5‐Aminolevulinic acid (ALA), an intermediate of the biological tetrapyrrole synthesis, can be used as a photodynamic herbicide/insecticide. Among the various microorganisms capable of its production, anoxygenic phototrophic bacteria produce ALA in considerable amounts, making it worthwhile to work toward commercial exploitation. Knowledge of the biochemical synthesis of ALA and its physiological and genetic regulation in microorganisms can enable the biotechnologist to manipulate them for enhancing ALA production for possible practical applications.

Promotive Effect of Priming with 5-Aminolevulinic Acid on Seed Germination Capacity, Seedling Growth and Antioxidant EnzymeActivity in Rice Subjected to Accelerated Ageing Treatment

“…However, this finding was in contrast to that reported by Zhang et al (2008) who found that the MDA content had a positive relationship with ALA treatment. This was probably due to the concentration of ALA employed in the experiment of Zhang et al (2008) was much higher than in our study (0.2 vs. 50 μg mL -1 , respectively), and ALA applied at a high concentration could act as a herbicide (Sasikala et al, 1994). The data of the present study also indicated that rice seed priming with ALA at a concentration of 0.2 μg mL -1 produced no harmful effects on the seedlings although the seed had been subjected to accelerated ageing treatment.…”

Ruthenium‐Catalyzed Conversion of Levulinic Acid to Pyrrolidines by Reductive Amination

“…For example, g-valerolactone may be used as a liquid fuel, food additive and solvent; [12] 5-aminolevulinic acid is a highly active, biodegradable, and nontoxic herbicide and insecticide. [13] Additionally, pyrrolidines, such as 5-methyl-N-(methyl, aryl, alkyl, cycloalkyl)-2-pyrrolidone, are used as industrial solvents, surfactants, and complexing agents. [14] They are also employed in pharmaceutical formulations, transdermal patch formulation, grease removal formulation, agrochemical composition and stripping formulation.…”
