Community of natural lactic acid bacteria and silage fermentation of corn stover and sugarcane tops in Africa.

Objective: To effectively utilize crop by-product resources to address the shortage of animal feed during the dry season in Africa, the community of natural lactic acid bacteria (LAB) of corn stover and sugarcane tops and fermentation characteristics of silage were studied in Mozambique.

Methods: Corn stover and sugarcane tops were obtained from agricultural field in Mozambique. Silage was prepared with LAB inoculant and cellulase enzyme and their fermentation quality and microbial population were analyzed.

Phylogenetic and evolutionary relationships between Elymus humidus and other Elymus species based on sequencing of non-coding regions of cpDNA and AFLP of nuclear DNA.

Species of the genus Elymus are closely related to some important cereal crops and may thus serve as potential alien genetic resources for the improvement of these crops. E. humidus is indigenous to Japan and is well adapted to a humid climate.
