Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 2,   Pages 253-261 doi: 10.15302/J-FASE-2018218

Abstract: Pre-harvest sprouting in wheat is the germination of seeds within the spikes when rains occur after orTherefore, 10 cultivars and five advanced lines of spring bread wheat were evaluated for pre-harvestand Ouassou-20 exhibited higher sprouting resistance while other genotypes were susceptible to pre-harvestwas conducted with six susceptible and two resistant genotypes to assess the genetic behavior of pre-harvestDoukkala-12 and BARS-09 showed increased pre-harvest sprouting resistance in their F descendants.

Microalgae

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 5,   Pages 784-791 doi: 10.1007/s11783-013-0590-4

Abstract: Renewable algae biomass, was used as substrate for generating electricity in two chamber microbial fuel cells (MFCs). From polarization test, maximum power density with pretreated algal biomass was 102 mW·m (951 mW·m ) at current generation of 276 mA·m . The individual electrode potential as a function of current generation suggested that anodic oxidation process of algae substrate had limitation for high current generation in MFC. Total chemical oxygen demand (TCOD) reduction of 74% was obtained when initial TCOD concentration was 534 mg·L for 150 h of operation. The main organic compounds of algae oriented biomass were lactate and acetate, which were mainly used for electricity generation. Other by-products such as propionate and butyrate were formed at a negligible amount. Electrochemical Impedance Spectroscopy (EIS) analysis pinpointed the charge transfer resistance (112 ?) of anode electrode, and the exchange current density of anode electrode was 1214 nA·cm .
