“…In an ideal fermentation, homolactic acid bacteria use water-soluble carbohydrates for growth and produce only lactic acid. However, the fermentation of forage crops is very complex and involves many types of microorganisms, resulting in a variety of different end products [43].…”

Industrial hemp (Cannabis sativa L.) is a plant species cultivated as a raw material for fiber extraction. Alternatively, hemp biomass can be used for feeding or energy purposes. This study was conducted to investigate the effect of inoculation with a lactic acid bacteria starter culture on the fermentation and chemical compositions of hemp silages. Hemp shoots (HS) and hemp flowers (HF) were ensiled in mini laboratory silos without or with the inoculation of the commercial starter culture Lactosil Biogaz (Lentilactobacillus buchnerii KKP 907 p; L. buchneri A KKP 2047 p; Pediococcus acidilactici KKP 2065 p). After 7 and 42 days of ensiling, the fermentation quality and chemical compositions of the silages were assessed. The use of Lactosil Biogas for hemp resulted in a decrease in pH, increase in lactic acid (LA), and reduction in fungal abundance in the HS silage. In the case of the HF silage, the bacterial inoculation was less effective; however, an increase in LA and a decrease in butyric acid (BA) were observed. As a result of the ensilage process, decreases in crude fiber and hemicellulose were observed in the HS and HF silages. Thus, hemp ensiling with biological additives is an effective pre-treatment of hemp plants for subsequent biofuel production that can preserve the biomass and provide the year-round availability of feedstock.

“…In the silage fermentation process, the homofermentative bacteria produce lactic acid without the loss of DM. However, the silage microbiota is also composed of heterofermentative bacteria (Lactobacillus parabuchneri and Lactobacillus buchneri) that in an acid environment (pH 3.8) promotes higher losses of dry matter with gas production at a rate of 0.52 mol CO 2 /mol of lactic acid [29]. This can be corroborated by the lower pH (3.90) and lower DM recovery (7.56% lower) observed in the silage of the giant cactus harvested at 24 months.…”

The objective of this study was to evaluate the effects of giant cactus harvest time and the inclusion of pigeon pea hay in improving the ensiling process and the nutritional composition of cactus silage. In total, 40 polyvinyl chloride-PVC mini-silos (10 × 40 cm) were used. Mini-silos were distributed in a 2 × 5 factorial scheme, referent to 2 harvest times (18 and 24 months) and 5 levels (0, 10%, 20%, 30%, and 40%) of pigeon pea hay inclusion in a randomized design. Effluent losses (p < 0.001) showed a negative linear effect as the inclusion of pigeon pea hay increased. Gas losses (p < 0.001), dry matter (DM) recovery (p < 0.001), and pH (p < 0.001) revealed the interactive effects between the pigeon pea hay inclusion and the harvest time. The DM content was higher in the giant cactus harvested at 24 months. The difference in nutritional composition promoted by the harvest time did not affect the silage quality. The gradual inclusion of pigeon pea hay improved the fermentative and bromatological characteristics of giant cactus silage. It is important to highlight that the inclusion of pigeon pea hay contributed to the increase in pH without affecting the necessary acidity for ideal conservation.

“…However, research indicates that this problem can be dealt with by the use of ensiling, commonly practiced as a method of preserving plant biomass for animal feed. This process involves the transformation of organic matter in the fermentation process carried out by lactic acid bacteria [130]. During the process, organic matter is lost.…”

The development of civilization is related to an increase in energy demand, while its production is still based mainly on fossil fuels. The release of carbon into the environment, which disturbs the balance of the global system, is the consequence of using these fuels. One possible way to reduce the carbon footprint of the energy sector is the widespread use of cover crops’ biomass for energy production. The aim of this paper is to critically review the knowledge on the dissemination of catch and cover crops’ cultivation in different regions of the world, and the yield, chemical composition and biomethane potential of their biomass. Additionally, the environmental benefits, as well as the challenges and opportunities associated with this biomass use in the energy sector, are considered. The review showed that the aboveground biomass of cover and catch crops is a valuable source for the production of bioenergy in biogas plants. However, the key role of these crops is to prevent soil degradation. Therefore, changes in biomass target use must be preceded by a multi-aspect analysis that allows their impact on the environment to be assessed.
