Recent advances in lactic acid production by microbial fermentation processes
927
TL;DR: This review will discuss lactic acid producers with relation to their fermentation characteristics and metabolism, and introduces inexpensive fermentative substrates, such as dairy products, food and agro-industrial wastes, glycerol, and algal biomass alternatives to costly pure sugars and food crops.

Highly efficient production of D-lactic acid from chicory-derived inulin by Lactobacillus bulgaricus.
TL;DR: Compared with separate hydrolysis and fermentation processes, simultaneous saccharification and fermentation (SSF) has demonstrated the best performance of d-lactic acid production from inulin by SSF, and represents a high-yield method for d- lactic Acid production from non-food grains.

TL;DR: It is concluded that zinc supplementation is not recommended in sour beer production using L. brevis WLP672 because the addition of magnesium ions resulted in the pH of the fermenting wort decreasing more quickly, an increase in the level of L-lactic acid and increased concentrations of some volatile compounds.

Second generation biofuels: high-efficiency microalgae for biodiesel production
Peer M. Schenk,Skye R. Thomas-Hall,Evan Stephens,Ute C. Marx,Jan H. Mussgnug,Clemens Posten,Olaf Kruse,Ben Hankamer +7 more
TL;DR: A review of second generation biodiesel production systems using microalgae can be found in this paper, where the main advantages of second-generation microalgal systems are that they: (1) have a higher photon conversion efficiency (as evidenced by increased biomass yields per hectare): (2) can be harvested batch-wise nearly all-year-round, providing a reliable and continuous supply of oil: (3) can utilize salt and waste water streams, thereby greatly reducing freshwater use: (4) can couple CO2-neutral fuel production with CO2 sequestration: (
