: Fermentation with continuous ball milling: Effectiveness ...

2020-3-1 Switchgrass, corn stover, and poplar were pre-rinsed as described in Garlock et al. , and then milled with a Retsch mill (Haan, Germany) through a 2-mm screen. For all lignocellulose feedstocks the substrate loading was 5 g L −1 glucan equivalent (14.8 g L −1 dry material for switchgrass, 17.0 g L −1 for corn stover, and 10.0 g L −1 for ...

2018-9-24 Switchgrass and alfalfa were harvested at the Bio Century Research Farm at Iowa State University. Soy hulls were procured through Ag Processing, Inc., Eagle Grove, IA. Biomasses were dried in a convection step oven at 105 °C for 12 h, ground to 2 mm particle size in a Wiley ball mill and stored in Ziploc bags at 25 °C.

2021-8-12 The load exerted by grinding balls on lignocellulosic biomass in a vibratory ball mill is significantly larger than the other mill types, resulting in the highest enzymatic hydrolysis yield. The glucose yields achieved were 95.2, 75.2, 61.0, and 52.8%, for vibratory ball mill, tumbler ball mill, jet mill, and centrifugal mill, respectively ...

Rock and Roll: a simple ball mill. Jeff Davis June 18, 2006. In order to make my first batch of fireballs I needed some charcoal fines or dust. I charred some switchgrass and leaves to start with. That would be easy to reduce, but was unsure how to go about this task at hand. Having already removed the paddles from the cement mixer, I got the ...

: Combined effect of pelleting and pretreatment on

2012-7-1 Switchgrass was pelleted to evaluate the effect of densification on acidic and alkaline pretreatment efficacy. Bulk density and durability of pellets were 724 kg/m 3 and 95%, respectively. Ground switchgrass (D 90 = 21.7 mm) was further ground to a fine power (D 90 = 0.5 mm) in the pellet mill prior to densification.This grinding increased enzymatic hydrolyzate glucose yields of non

2018-9-4 Switchgrass (Panicum virgatum L.) is a promising bioenergy feedstock because it can be grown on marginal land and produces abundant biomass. Recalcitrance of the lignocellulosic components of the switchgrass cell wall to enzymatic degradation into simple sugars impedes efficient biofuel production. We previously demonstrated that overexpression of OsAT10, a BAHD acyltransferase
