TL;DR: The citric acid yield and the conversion rate of glucose of chsC-3 were both improved by 3.6%, when compared with that of the original strain in the stirred tank bioreactor, and the high-yield strain chsD-3 exhibited excellentcitric acid production potential in the scale-up process.

TL;DR: When PLA 1 was bio-imprinted with 5% soybean lecithin at pH 5.0, its phospholipase (PLA) activity in leCithin–hexane solution increased by 30.9-fold and its substrate specificity was substantially enhanced, and a further increase in PLA activity of the bio-IMprinted PLA 1 (bi-PLA 1 ) was obtained.

TL;DR: Fermentation conditions of Beauveria bassiana and Metarhizium anisopliae s.l. were optimised to increase the conidial yields that reached 11.2 mg/g and 24.5 mg/G, increases of 72% and 52% compared to the unoptimised yields, and response surface methodology combined with a Box–Behnken design was employed to enhance the harvest efficiency.

TL;DR: In this article, the authors reported an increase in PLA activity in lecithin-hexane solution by 30.9-fold and its substrate specificity was substantially enhanced when 105mg diatomite/mg bi-PLA1 was incorporated as an immobilization carrier.

TL;DR: Prenylated quinones, especially menaquinones, have significant physiological activities, but are arduous to synthesize efficiently, due to the relaxed aromatic substrate specificity and prenylation regiospecificity at the ortho- site of the phenolic hydroxyl group, the aromatic preNyltransferase NovQ from Streptomyces may be useful in menaquinone synthesis from menadione.
