Levulinic acid production from wheat straw.
TLDR
The coefficient determination (R(2)) was good for the second-order model and the optimal conditions for levulinic acid production from wheat straw were 209.3 degrees C, 3.5% acid concentration, 15.6 liquid:solid ratio and 37.6 min of reaction time resulted 19.86% yield.About:

Production of levulinic acid and ethyl levulinate from cellulosic pulp derived from the cooking of lignocellulosic biomass with active oxygen and solid alkali
TL;DR: In this paper, the acid-catalyzed hydrolysis or ethanolysis of cellulosic pulp was optimized by response surface methodology (RSM), offering desirable LA yield of 65.3% or EL yield of 62.7%, which is significantly higher than those obtained from raw biomass.

A response surface approach for the comparison of lipase production by Candida cylindracea using two different carbon sources
TL;DR: Medium containing olive oil appears to a better medium for fermentative production of C. cylindracea lipase than yeast extract, malt extract, peptone and tween 80, based on experimental conditions.

Mechanism of levulinic acid formation
TL;DR: Based on the intermediates revealed by 13C-NMR spectroscopy, the mechanism of levulinic acid formation in acid catalysed hydrolysis of 2-hydroxymethylfurane (1) and 5-hexyl carbaldehyde (2-carbaldehyde) is proposed in this paper.

Experimental studies for levulinic acid production from whole kernel grain sorghum
Qi Fang,Milford A. Hanna +1 more
TL;DR: This study proposed a method of making levulinic acid using abundant and low cost whole kernel sorghum grain as the raw material and a linear regression model was capable of predicting the levulini acid yield with respect to effects of reaction temperature, mineral acid concentration and flour loading.
