PRS3, RPB4 and ZWF1 were previously identified as key genes for yeast tolerance to lignocellulose-derived inhibitors. To better understand their contribution to yeast resistance to the multiple stresses occurring during lignocellulosic hydrolysate fermentations, we overexpressed these genes in two industrial Saccharomyces cerevisiae strains, CCUG53310 and PE-2, and evaluated their impact on the...

Excessive concentrations of nitrate in ground water are known to cause human health hazards. A submerged membrane adsorption hybrid system that includes a microfilter membrane and four different adsorbents (Dowex 21K XLT ion exchange resin (Dowex), Fe-coated Dowex, amine-grafted (AG) corn cob and AG coconut copra) operated at four different fluxes was used to continuously remove nitrate. The ex...

−Dilute acid pretreatment of lignocellulosic material is one of the significant steps in a biorefinery. We used response surface methodology to determine the important factors of formic acid concentration (2%-6% wt%), treatment time (30-150 min), reaction temperature (120-160 oC), and liquid to solid ratio (3-11 mL/g) on dilute acid hydrolysis of corn cob to produce xylose. A xylose yield of 81...

The orientation of cell expansion is a process at the heart of plant morphogenesis. Cellulose microfibrils are the primary anisotropic material in the cell wall and thus are likely to be the main determinant of the orientation of cell expansion. COBRA (COB) has been identified previously as a potential regulator of cellulose biogenesis. In this study, characterization of a null allele, cob-4, e...

The final step in the conversion of vitamin B(12) into coenzyme B(12) (adenosylcobalamin, AdoCbl) is catalyzed by ATP:cob(I)alamin adenosyltransferase (ATR). Prior studies identified the human ATR and showed that defects in its encoding gene underlie cblB methylmalonic aciduria. Here two common polymorphic variants of the ATR that are found in normal individuals are expressed in Escherichia col...

Liquid waste from batik industry often causes environmental problems, because there is a pollutant content of Biochemical Oxygen Demand (BOD). Corn cobs and husks contain high cellulose which has the potential to become activated carbon. This study aims analyze bioadsorbent mixture corn in reducing BOD levels wastewater. type research pre-experimental, design One Group Pretest Posttest Design. ...

The use of organic matter, which has a long-term impact, increases soil fertility because it contains residue. research examines how rice straw mulch and fertilizer residue affect glutinous corn yield. This study was carried out at the Faculty Agriculture Field Laboratory, Halu Oleo University, from May to August 2022. Experiment used randomized block design with split plot design. main plot, i...

BACKGROUND:Moisture has an essential role at threshing of breeding material corn, as when mois-ture is too low (material dry) shattering corn seed takes place while and becomes inapplicable to use, whereas increased moisture leads underthreshing microtraumas, invisible the na-ked eye, that significantly reduces germination material.
 AIMS:To define dependence kernel strength on moisture, c...

One of the basic needs people i Indonesia is corn. Corn one most important food crops after rice and wheat. Apart from being a human ingredient (a sourdc carohydrates), corn also used as anumal feed an industrial raw materil. The need for animal continuesin to increase every yera. This in line with developmentof livestoc industry, especially Lima Puluh Kota regency. Some factors that cause pote...

Ag4Bi2O5/MnO2 nano-sized material was synthesized by a co-precipitation method in concentrated KOH solution. The morphology characterization indicates that MnO2 nanoparticles with a size of 20 nm are precipitated on the surface of nano Ag4Bi2O5, forming a structure like corn on the cob. The obtained material with 60% Mn offers slightly higher initial potential (0.098 V vs. Hg/HgO) and limiting ...
