TL;DR: Rice straw appeared to be the best alternate substrate for growing oyster mushrooms based on the yield and BE of the substrates tested, and the yield was positively correlated to cellulose, lignin, fibre and fibre contents of the substrate.
Abstract: Eight lignocellulosic by-products were evaluated as substrates for cultivation of the oyster mushroom, Pleurotus ostreatus ( Jacq. ex. fr) Kummer. The yields of mushroom on the different substrates were 183.1, 151.8, 111.5, 87.8, 49.5, 23.3, 13.0 and 0.0 g for composted sawdust of Triplochiton scleroxylon, rice straw, banana leaves, maize stover, corn husk, rice husk, fresh sawdust, and elephant grass, respectively. The biological efficiency (BE) followed the same pattern and ranged from 61.0% for composted sawdust to 0.0% for elephant grass. The yield of mushroom was positively correlated to cellulose ( r(2) =0.6), lignin ( r(2) =0.7) and fibre ( r(2) =0.7) contents of the substrates. Based on the yield and BE of the substrates tested, rice straw appeared to be the best alternate substrate for growing oyster mushrooms.

TL;DR: In this paper, the effect of using an in-situ catalyst based on a HZSM-5 zeolite in flash pyrolysis with an inert gas (N{sub 2}) of pinus insignis sawdust in a conical spouted-bed reactor in the 400--500 C range and for a gas residence time of 50 ms.
Abstract: The effect was studied of using an in-situ catalyst based on a HZSM-5 zeolite in flash pyrolysis with an inert gas (N{sub 2}) of pinus insignis sawdust in a conical spouted-bed reactor in the 400--500 C range and for a gas residence time of 50 ms. The use of the catalyst increases the yield of gases and decreases the yields of liquid and char. Likewise, the yield of CO{sub 2} decreases, whereas the yield of C{sub 4{minus}} hydrocarbons increases (15.9 wt. % at 450 C). The catalyst is efficient for partial deoxygenation of the liquid product.

TL;DR: The decrease in aliphatic organics in HA demonstrated the degradation of the readily available organics, while an increase in aromatic functional groups indicated the maturity of compost.

TL;DR: In this article, the authors investigated the energy consumption and pellet properties of torrefied sawdust from a fluidized bed reactor, including moisture adsorption, pellet density and Meyer hardness.

TL;DR: The kinetic parameters obtained in a batch process were used to scale-up the process on a mini-column and to choose the breakthrough model, and experimental data concerning the volumes treated were correlated using the bed depth service time model.
