Fed‐batch l‐(+)‐lactic acid fermentation of brewer's spent grain hydrolysate
Brewer's spent grain (BSG) hydrolysates were used for l-(+)-lactic acid (LA) fermentation by Lactobacillus rhamnosus ATCC 7469. The aim of this study was to evaluate fed-batch LA fermentation of BSG
Evaluation of biological production of lactic acid in a synthetic medium and in Aloe vera (L.) Burm. f. processing by-products
TLDR
Results show the potential for transformation of sugars that strain USBA-018 offers, but additional studies are needed to find out if different strategies using AHE as carbon source can produce large enough quantities of lactic acid to allow AHE to become a low-cost alternative substrate.
Brewery Waste Reuse for Protease Production by Lactic 
Acid Fermentation.
This study evaluated the use of three solid brewery wastes: brewer's spent grain, hot trub and residual brewer's yeast, as alternative media for the cultivation of lactic acid bacteria to evaluate
Feasibility of exhausted sugar beet pulp as raw material for lactic acid production.
TLDR
An efficient fed-batch SSF strategy with pH control and MRS supplementation is described, attaining higher LA productivities compared to separate hydrolysis and fermentation (SHF) and SSF.
Application of consolidate enzymatic system of Fusarium and Saccharomyces to enhance the production of ethanol from spent grain
TLDR
Efficient bioethanol production was achieved using the ligno-cellulolytic degrading enzyme machinery of F. oxysporum and Saccahromyces cerevisiae as source of enzymes for simultaneous saccharification and fermentation of spent grain into ethanol.
The effects of nutrient supplements on the production of lactic acid from cheese whey
Purpose: To investigate the effects of microorganism strain, substrate concentration and yeast extract (w/v), MnSO 4 .H 2 O, MgSO 4 .7H 2 O addition to cheese whey solution on the lactic acid
Total reuse of brewer’s spent grain in chemical and biotechnological processes for the production of added-value compounds
Brewer’s spent grain was fractionated by means of three different procedures: dilute acid hydrolysis, for the hemicellulose recovery; alkaline hydrolysis, for the lignin solubilization, and enzymatic
High-titer and productivity of l-(+)-lactic acid using exponential fed-batch fermentation with Bacillus coagulans arr4, a new thermotolerant bacterial strain
TLDR
This study presents the highest productivity of lactic acid ever observed in the literature, on the fermentation of thermotolerant Bacillus sp.

Acid hydrolysis and fermentation of brewer's spent grain to produce xylitol
The hemicellulosic fraction of brewer's spent grain (BSG) was hydrolysed with diluted acid under different conditions of liquid/solid ratio (8–12 g g−1), sulfuric acid concentration (100–140 mg g−1
Batch and repeated batch production of l(+)-lactic acid by Enterococcus faecalis RKY1 using wood hydrolyzate and corn steep liquor
TLDR
Lactic acid productivity could be maximized by conducting a cell-recycle repeated batch culture of E. faecalis RKY1 and the maximum productivity for this process was determined to be 4.0 g l−1 h−1.
