TL;DR: In order to investigate the effect of feedstock ratios in biogas production, anaerobic co-digestions of rice straw with kitchen waste and pig manure were carried out and the optimal ratio of kitchen waste, pig manure, and rice straw was 0.4:1.

TL;DR: A simple, low-cost single-chamber microbial fuel cell (SCMFC)-type biochemical oxygen demand (BOD) sensor using carbon felt and activated sludge is developed, and its feasibility in the construction of a real-time BOD measurement system is demonstrated.

TL;DR: The effect of variable sodium concentrations on the anaerobic digestion performance of Sargassum sp was investigated, and the variation in bacterial and archaeal communities was analyzed by high-throughput gene sequencing Results showed that the maximum methane yield of 29041 ± 3421 mL of CH4 g−1 of volatile solids was obtained at a sodium concentration of 442 g L−1, increased by 381% compared to the control group as mentioned in this paper.

TL;DR: In this paper, the central composite surface response methodology was used to optimize the process variables (temperature, reaction time and liquid-to-solid ratio) in liquid hot water pretreatment for biomethane production from the anaerobic digestion of Hybrid Pennisetum (a typical energy crop in southern China).

TL;DR: In this article, different multivariate regression models were established between BMP and the physicochemical indexes or near-infrared spectroscopy (NIRS), and the results reveal that the predicted accuracy of NIRS model is very high, and meet the requirements of rapid prediction of BMP for co-digestion feedstocks in practical biogas engineering.
