Orange juice waste obtained industrially under the conditions described in the present study could be used as a source of pectic derivatives or fructose in the case of solid or liquid by-products, respectively. The results reported here could diversify the present application of these products as a source of food ingredients, contributing to an improvement in their utilization. © 2018 Society of Chemical Industry.

“…The ML could provide valuable nutrients for lactic acid fermentation. 35 In contrast, SSL had worse fermentation quality than the control, as evidenced by higher acetic acid (P = 0.001) and ammonia-N (P < 0.001) content, and the lower ratio of lactic acid to acetic acid (P = 0.038). On the other hand, all silages exceeded the pH threshold of 4.2 for well preserved silage, 36 which indicated poor fermentation quality.…”

BACKGROUND The use of alfalfa is a promising response to the increasing demand for squalene. Ensiling could enhance the squalene content of fresh alfalfa and silage. To investigate and exploit the anaerobic fermentation of forage as a new squalene source, alfalfa was ensiled without (CON) or with molasses (ML) and sunflower seed oil (SSL) for 10, 40, and 70 days. RESULTS Naturally ensiled alfalfa was of poor quality but had up to 1.93 times higher squalene content (P < 0.001) than fresh alfalfa. The squalene‐producing bacteria were found to be cocci lactic acid bacteria (LAB). Adding ML and SSL decreased squalene content (P = 0.002 and P < 0.001) by 6.89% and 11.6%, respectively. Multiple linear regression models and correlation analysis indicated that squalene synthase was the key enzyme for squalene synthesis. The addition of ML and SSL altered the structure of LAB communities, mainly decreasing the relative abundance of cocci LAB, which was responsible for squalene synthesis, and changing the fermentation products (lactic acid, propionic acid, and ammonia‐N) influencing the squalene‐related enzymes, thereby decreasing squalene production. Compared with squalene production from the reference bacteria (Pediococcus acidilactici Ch‐2, Rhodopseudomonas palustris, Bacillus subtilis, engineered Escherichia coli), alfalfa silage had the potential to be a new squalene source. CONCLUSION Natural ensiled alfalfa was a promising source for squalene, and ensiling was a potential pathway to obtain novel high‐yield squalene bacteria. © 2022 Society of Chemical Industry.

“…Panesar et al [37] reported the production of 33.73 g•L −1 L-LA using L. casei, while Taleghani et al [38] reported a value of 32.1 g•L −1 when whey was fermented by L. bulgaricus. Molasses derived either from sugarcane or sugar beets fermentation to lactic acid has also been investigated, using various LAB strains [39][40][41]. In the recent work of Sun et al [41], a microbial consortium in which Clostridium sensu stricto was the predominant strain was tested for sugarcane molasses fermentation to lactic acid.…”

Batch and Continuous Lactic Acid Fermentation Based on A Multi-Substrate Approach

The utilisation of waste materials and industrial residues became a priority within the bioeconomy concept and the production of biobased chemicals. The aim of this study was to evaluate the feasibility to continuously produce L-lactic acid from different renewable substrates, in a multi-substrate strategy mode. Based on batch experiments observations, Bacillus coagulans A534 strain was able to continuously metabolise acid whey, sugar beet molasses, sugar bread, alfalfa press green juice and tapioca starch. Additionally, reference experiments showed its behaviour in standard medium. Continuous fermentations indicated that the highest productivity was achieved when molasses was employed with a value of 10.34 g·L−1·h−1, while the lactic acid to sugar conversion yield was 0.86 g·g−1. This study demonstrated that LA can be efficiently produced in continuous mode regardless the substrate, which is a huge advantage in comparison to other platform chemicals.
