Taco-Vasquez S, Holtzapple M
PLoS One . 2022 Nov; 17(11):e0277184. PMID: 36409721
In this study, two different feeds were treated to produce hydrocarbons: (1) reagent-grade acetone, and (2) mixed ketones obtained from lignocellulosic biomass via the carboxylate platform. Acetone and mixed ketones...

Holtzapple M, Wu H, Weimer P, Dalke R, Granda C, Mai J, et al.
Bioresour Technol . 2021 Nov; 344(Pt B):126253. PMID: 34728351
The carboxylate platform employs a diverse microbial consortium of anaerobes in which the methanogens are inhibited. Nearly all biomass components are digested to a mixture of C1-C8 monocarboxylic acids and...

Mroue A, Mohtar R, Pistikopoulos E, Holtzapple M
Sci Total Environ . 2018 Oct; 648:1649-1664. PMID: 30340308
The paper introduces a holistic framework that identifies the links between energy and other systems (water, land, environment, finance, etc.), and measures the impact of energy portfolios, to offer a...

Darvekar P, Holtzapple M
Appl Biochem Biotechnol . 2015 Nov; 178(6):1081-94. PMID: 26596582
Corn stover was pretreated with lime and shock, a mechanical process that uses a shockwave to alter the biomass structure. Two pretreatments (lime-only and lime + shock) were evaluated using...

Cope J, Hammett A, Kolomiets E, Forrest A, Golub K, Hollister E, et al.
Bioresour Technol . 2014 Feb; 155:388-94. PMID: 24502857
To test the hypothesis that microbial communities from saline and thermal sediment environments are pre-adapted to exhibit superior fermentation performances, 501 saline and thermal samples were collected from a wide...

Golub K, Forrest A, Wales M, Hammett A, Cope J, Wilkinson H, et al.
Bioresour Technol . 2013 Jan; 130:739-49. PMID: 23334035
Using a mixed culture of microorganisms, the carboxylate platform converts biomass into hydrocarbons and chemicals. To develop a method that identifies the highest performing inoculum for carboxylate fermentations, five bacterial...

Ahmadi F, Rad A, Holtzapple M, Zamiri M
J Sci Food Agric . 2012 Dec; 93(8):2061-70. PMID: 23239410
Background: Oxidative lime pretreatment (OLP) is an effective pretreatment for highly recalcitrant lignocellulosic materials. This experiment was conducted to investigate the effect of short-term OLP on fermentative gas production kinetics...

Golub K, Golub S, Meysing D, Holtzapple M
Bioresour Technol . 2012 Sep; 124:146-56. PMID: 22995159
To increase conversion and product concentration, mixed-acid fermentation can use a countercurrent strategy where solids and liquids pass in opposite directions through a series of fermentors. To limit the requirement...

Hollister E, Forrest A, Wilkinson H, Ebbole D, Tringe S, Malfatti S, et al.
PLoS One . 2012 Jul; 7(6):e39689. PMID: 22761870
The carboxylate platform is a flexible, cost-effective means of converting lignocellulosic materials into chemicals and liquid fuels. Although the platform's chemistry and engineering are well studied, relatively little is known...

Forrest A, Hollister E, Gentry T, Wilkinson H, Holtzapple M
Bioresour Technol . 2012 Jun; 118:343-9. PMID: 22705541
The MixAlco™ process biologically converts biomass to carboxylate salts that may be converted to a variety of chemicals and fuels. This study examines the fermentation performance of six different mixed...
