A method is provided for fabricating a catalyst carrier. At first, aluminum hydroxide is used for forming an alumina powder. The alumina powder is mixed with carbon nanotubes and a complex additive to be shaped into a cake. The cake is kneaded into a noodle-like shape to be hot-dried. Then, calcination is processed in a furnace under 1200 celsius degrees (&#xb0; C.) with air passed through. The crystal structure remains without phase change. A catalyst carrier of &#x3b1;-alumina having nano-scaled pores is formed. The catalyst carrier is a powdery material made into different three-dimensional forms. The catalyst carrier thus fabricated is suitable for generating hydrogen through methane reformation. The catalyst carrier has a methane conversion greater than 99 percents. The catalyst carrier will not be crumbled under 800&#xb0; C. for 4000 hours without carbon deposit.

A method for producing xylitol by fermentation of lignocellulosic hydrolysates without detoxification is provided. By using the originally isolated yeastsp., xylose can be effectively converted into xylitol. The invention also provides thestrain having high furfural tolerance, and is capable to produce xylitol from various types of non-detoxified lignocellulosic hydrolysates, in which the overall utilization of xylose in hydrolysate can reach over 95%.

A method for preparing a xylose-utilizing strain ofand theare introduced. The preferred recombinant strain contains multiple copies of integrated xylose metabolic genes, and can rapidly ferment xylose to produce ethanol from synthetic medium and lignocellulosic raw materials. The xylose-utilizing strain is applicable for the cellulosic ethanol production industry and brewing industry.

Method for preparing xylose-utilizing strain

A cellulose hydrolase and a gene thereof are obtained by screening a cDNA genomic library constructed withsp. Y102. The gene is 1071 base pairs long and comprises an open reading frame (ORF) for producing the cellulose hydrolase comprising 357 amino acids by translation. A transformed cell and a carrier carrying the gene are introduced. The gene is transferred toby transformation, such thatcan acquire activity of decomposing CMC, beta-glucan, and xylan. The cellulose hydrolase is multifunctional and is capable of decomposing cellubiose and directly decomposing fiber into glucose.

A method for culturing the yeast for enhancing pentitol production is provided. The yeast cultured according to the present disclosure is. Application of the yeast in pentitol production by fermention of the lignocellulosic hydrolysate or the xylose-to-pentitol production yield can be enhanced 3 to 6 times from the non-detoxified or the overliming-processed lignocellulosic hydrolysate.

Method of cultivating yeast for enhancing pentitol production

Disclosed is a method for increasing the concentration of xylose in lignocellulosic hydrolysate. The method includes the step of extruding lignocellulosic material and mixing the lignocellulosic material with diluted acid and the step of conducting hot-water extraction on the mixture. Hence, the concentration of the xylose in the lignocellulosic hydrolysate can achieve a high concentration of 60 g/L, and the yield of the xylose can reach to 90%.

Through a low-dose irradiation, a seaweed's growth becomes fast and its production is improved as well. By doing so, a material for biomass energy is provided.

Method of hormesis for seaweed through irradiation

A wild seaweed, like sea lettuce, is picked and germ cells are released from the seaweed. The germ cells then obtain adherence and are sprouted into youngs of the seaweed so that the seaweed can be cultivated artificially and productively and can be supplied as a material for biomass energy.
