The formation of polyols and fatty acids during l-lactic acid fermentation by rhizopus arrhizus
TLDR
The formation of 10 g polyols/L (glycerol, arabitol, xylitol) during L-lactic acid synthesis by Rhizopus arrhizus was observed, resulting in a subsequent rise in the lipid content of the mycelium.Abstract:
The formation of 10 g polyols/L (glycerol, arabitol, xylitol) during L-lactic acid synthesis byRhizopus arrhizus was observed. Consumption of polyols after glucose exhaustion was discovered resulting in a subsequent rise in the lipid content of the mycelium. Lactate utilization was not detected.read more

Production of L(+)-lactic acid using immobilized rhizopus oryzae reactor performance based on kinetic model and simulation
Haluk Hamamci,Dewey D. Y. Ryu +1 more
TL;DR: In this paper, the production of L(+)-lactic acid using alginate immobilizedRhizopus oryzae in tapered-column fluidized-bed batch reactor was tested and simulated using the kinetic data taken independently in shake-flask cultures.

Physiological restriction of the L‐lactic acid production by Rhizopus arrhizus
M. Rosenberg,L. Krišofíková +1 more
TL;DR: The intensity of lactic acidProduction in the inoculum was proportional to its production in the subsequent steps of fermentation and can be used as a fast control of the physiological state of the producers.

Lipid accumulation in Trichoderma species
TL;DR: Two filamentous fungi, Trichodma harzianum and Trichoderma viride, were compared for their ability to synthesize lipids on different carbon and nitrogen sources: the glucose-ammonium sulphate medium was the most conducive to lipid production.

A rapid method of total lipid extraction and purification.
E. G. Bligh,W. J. Dyer +1 more
TL;DR: The lipid decomposition studies in frozen fish have led to the development of a simple and rapid method for the extraction and purification of lipids from biological materials that has been applied to fish muscle and may easily be adapted to use with other tissues.

Preparation of Milk Fat Methyl Esters by Alcoholysis in an Essentially Nonalcoholic Solution
TL;DR: In this article, the authors show that the mixture of a 10% solution of milk fat in petroleum ether with 1/2 n methanolic potassium hydroxide or sodium methoxide at room temperature results in the almost instantaneous formation of methyl esters from glyceride fatty acids.

An improved colorimetric assay for polyols
Song Hae Bok,Arnold L. Demain +1 more
TL;DR: A new assay for polyols was developed that minimizes interference by sugars based on oxidation of alditols to formaldehyde by acidic periodate, reduction of the excess periodate with l -rhamnose, and a short-time determination of the formaldehyde with the Nash reagent.
