The efficiency of the symbiotic process between alfalfa (Medicago sativa L.) and Sinorhizobium meliloti can be drastically affected by soil nitrogen. This research evaluates how mineral fertilization affects the contribution of symbiosis to the yield and quality of alfalfa in two experiments under controlled conditions, and a third one in the field. Under controlled conditions, positive effect of nitrogen fertilizer was observed, whereas, in the field, negative effect of the mineral nitrogen (450 kg ha-1 year-1 ) on the symbiotic process was observed, with reduction of nodulation and nitrogenase activity. However, there was no effect on yield, total nitrogen concentration, crude protein, non-protein nitrogen and digestibility in relation to the treatment without mineral N. The cultivars showed similar performance under different conditions, with ?Crioula Brasileira? and ?Crioula Chilena? showing the highest yield and ?Pioneer-5454? the highest forage nutritive value. |

This work investigates the effects of the co-culture between the filamentous fungus Panus lecomtei and the yeast Sporidiobolus pararoseus in the production of laccases. The variations of time interval and inoculum volume of S. pararoseus in co-cultures with P. lecomtei stimulated laccase production, reaching its highest activity at nearly 2960.7 ± 244 U/mL with a maximum time point of 120 h and 2.0% (v/v), respectively. Further application in the pretreated sugarcane bagasse hydrolysis was performed, using P. lecomtei and S. pararoseus extract added to an enzyme mixture from the co-culture of P. lecomtei and Trichoderma reesei that positively favored the hydrolysis efficiency by 66.87%. Furthermore, the addition of P. lecomtei and S. pararoseus extract increased the degradation of industrial anthraquinone Remazol Brilliant Blue R by 78.98%. As a result, the extract derived from the co-culture of P. lecomtei and S. pararoseus rich in laccases presents potential in biotechnological applications, being suitable in the hydrolysis of lignocellulosic biomass and the degradation of unwanted dyes released in the environment. |
