(2019-01-01)
Lactic acid is an organic acid that has been extensively used worldwide in a variety of industrial and biotechnological applications. Lactic acid can be obtained chemically or by microbial fermentation. Production by ...
Sialic acids in fungi: A minireview
(Kluwer Academic Publ, 1999-09-01)
The increasing number of reports on the presence of sialic acids in fungi (N-acetyl, N-glycolyl-and 5,9-N,O-diacetyl neuraminic acids) based on direct and indirect evidence warrants the present review. Formerly suggested ...
Highly selective acetalization of glycerol with acetone to solketal over acidic carbon-based catalysts from biodiesel waste
(Elsevier Sci Ltd, 2016)
The glycerol acetalization reaction in the presence of acetone was evaluated using acidic carbon-based catalysts from biodiesel waste as catalysts. Acidic carbon-based catalysts were prepared with different glycerin: ...
