Abstract: The progression of the organic loading rate (OLR) up to a certain limit increases biogas production. The limit and operation range vary according to the configuration of the reactor and are associated with other variables that generate different results with respect to biogas yield (BY) and biogas productiveness (BP). The aim of this study was to investigate the effect of the OLR on the BY and BP from swine manure in continuous stirred tank reactors (CSTRs) and upflow anaerobic sludge blanket reactors (UASBs). In the assay with the CSTR, the best operational condition was at an OLR of 0.7 gVS add L−1 reactor d−1 and a hydraulic retention time (HRT) of 18 days. At this operational condition, 0.8 LN biogas gVS add−1 of BY and 0.6 LN biogas L−1 reactor d−1 of BP were obtained. In the assay with the UASB, the best operational condition was at an OLR of 2.2 gVS add L−1 reactor d−1 and an HRT of two days, and 0.7 LN biogas gvs add−1 of BY and 1.6 LN biogas L−1 reactor d−1 of BP were obtained. The results demonstrate the effects of OLR changes on the biogas production in the CSTR and UASB, avoiding the underutilization or overloading of such equipment and enabling collaboration in projects for power generation from biogas in swine farms. |

Mid-year report: 1. Delayed post harvest deterioration (PPD): three backcross populations (BC1), from controlled crossing of the PPD resistant genotype CW 429-1 to two elite genotypes (MTAI 8 and SM 909-25) and open pollination, were developed to identify molecular markers associated with delayed PPD for efficient transfer into cassava gene pools. The BC1 populations were established in vitro from embryo axes, micro-propagated, and 4-10 plants per genotype established in the field. The BC1 populations were harvested in March 2007 and evaluated for PPD at the 7th and 14th day after harvest. In the BC1 family B1PD280, derived from open-pollinated (OP) seeds from CW429-1, 23% of individuals showed delayed PPD trait at 14 days after harvest (DAH). In the BC1 families B1PD 284, cross of CW 429-1 and MTAI 8, and B1PD289, cross of CW 429-1 and SM 909-25, 14.3% and 5.8% respectively of genotypes revealed resistance to PPD. Frequency distributions of delayed PPD in these families are shown in Appendix 1 and 2. The evaluations will be repeated for a second year in a replicated trial of 8 plants per plot and 3 replications. BC1 genotypes with delayed PPD were selected and crossed with CMD resistant genotypes to combine the two traits thus facilitate the testing and use of PPD delayed lines in breeding programmes by NARs partners in Africa. Currently a total of about 6000 crosses have been made and fruits are being harvest for embryo rescue to facilitate shipping of in vitro plants to project partners. MenosMid-year report: 1.
