Global Challenges, Volume 10, Issue 2, February 2026.ABSTRACT A study conducted in Egypt evaluated the effectiveness of chemical and microbial agents in enhancing sweet pepper (Capsicum annuum var. annuum) defenses against major pests Aphis gossypii and Thrips tabaci and their natural predators, Chrysoperla carnea and Orius insidiosus. Five foliar treatments were tested under greenhouse conditions during

On the Formation of Acetoin by Acetobacter [PDF]
Journal of General Microbiology, 1959 SUMMARY: The formation of acetoin was studied with 44 strains of the genus Acetobacter, when growing on a medium containing DL-lactate as the main carbon source. Most of the strains produced only limited amounts of acetoin. However, strains of the species A.

Acetolactate and Acetoin Synthesis in Ripening Peas [PDF]
Plant Physiology, 1964 The role of acetolactate as a precursor in valine biosynthesis was first indicated by the isotopic studies of Strassman et al. (18) and was subsequently supported by work on valine-less mutants of Escherichia coli (21, 22) and Neurospora, crassa (24).
