“…In the present study, the same tendency was found. The previous study reported that moisture content affected the consumption of charged ozone in Japanese cedar and ozone consumption decreased when moisture content was higher than 40 % [22]. In general, when water surrounds a sample, ozone needs to approach the sample through the water.…”

Ozone oxidation pretreatment for enzymatic saccharification of spent culture media after Lentinula edodes cultivation

et al. 2014

Ozone oxidation pretreatment was carried out on spent culture media (SCMs) after Lentinula edodes cultivation to improve fermentable sugar production by enzymatic saccharification. SCM samples treated with ozone for different treatment time under various moisture contents (MCs) were enzymatically saccharified, and hydrolysis weight decrease, reducing sugar yield, and monosaccharide yields were determined. Klason lignin content in SCM samples with 20 and 40 % MC was greatly decreased by ozone pretreatment for all ozone treatment time. In addition, in the ozone-treated sample at 40 % MC, the highest hydrolysis weight decrease after saccharification was obtained in the SCM sample treated for 1 h. After saccharification, glucose yield from the ozone-treated sample for 1 h was higher than that treated for 2 h. These results indicate that ozone treatment is effective to improve fermentable sugar production by enzymatic saccharification for the SCMs of L. edodes.

“…On the other hand, the 80 % MC sample showed almost no changes in Klason lignin after ozone treatment. It is known that the MC of the sample affects the ozonolysis of lignocellulose [16,17,22]. The optimal MC of sample for ozone treatment is different by type and condition of sample [16,17].…”

“…In the ozone-treated product, glucose yield increased from 61.6% to 68.8%, removing the water soluble fraction. In contrast, the yields of xylose and mannose were reduced by washing [33]. Yu et al [34] reduced the total lignin content with loblolly pine and mixed southern hardwood pulps, with a maximum carbohydrate conversion in the latter of around 80%.…”

“…In types (i) and (ii), the reactor flow model approximated an ideal mixing model in which the ozone concentration in the reaction medium was the same as that in the reactor outlet flow, whereas in type (iii), the model approximated a plug flow reactor and the ozone concentration decreased through the reactor, from the inlet to the outlet. From these fundamental types of reactor, a variety of design alternatives have been employed in ozonolysis experiments, such as rotatory glass [31,33,37,38], semi batch tank reactor [11,30,34,35,37,55], stirred bed reactor [23], bubble column [41], layer fixed bed [5,16,26,27,39], rotating horizontal cylinder [23], and fixed bed column [3,12,13,17,24,30].…”

“…Use of ozone-generated plasmas to delignification of biomass was tested in laboratory scale by various groups for different types of biomass as sugarcane bagasse (Souza-Corrêa et al 2013a), wheat straw (Schultz-Jensen et al 2011) and Japanese cedar (Miura et al 2012). The technology is effective superior to conventional pre-treatment methods in terms of conversion efficiency of enzymatic hydrolysis, but more studies about the energy efficiency and economic point of view are needed.…”

Low-temperature plasmas are present in a broad field of technological applications and experimented an enormous growth after the end of the twentieth century. The most important examples of applications are lamps, pretreatment of polymer materials, packaging materials, treatment of surfaces, waste, air pollution mitigation, microelectronics, and flat panels display. Recently new applications in medicine, pharmacy, foods, biology, biomass and biofuel processing, attracted the interest of the industry and the scientific community.The purpose of this chapter is not to be exhaustive but illustrates some important industrial and technological applications. The fields where low-temperature plasmas are being employed today is vast, rapidly growing, and cannot be described in a single book chapter, so clearly well beyond this textbook. Of course, much will be left out, however a special emphasize will be stressed here in these new breakthrough applications of plasmas in health science, production of biofuels and agriculture. Plasmas for Materials ProcessingPlasma technologies are being used in industry due to their ability to offer a wide spectrum of possible treatments of materials. These plasmas are in fact source of heat and reactive species that have unique physical and chemical properties induced by charged particles. The main applications of these discharges are (Bonizzoni and Vassallo 2002): destruction of toxic/harmful materials, superficial modification of materials and creation of new materials.In industry basically two kind of plasmas are employed; the plasma torches which are thermal plasmas produced at high pressure by direct current, alternating electric fields like RF or microwaves. These plasmas have electron temperatures around
