1. The production of a new lysergic acid derivative, identified as D-lysergic acid α -hydroxyethylamide, in submerged culture and in yields up to 1 mg/ml. and above, by a strain of Claviceps paspali Stevens & Hall is reported; this substance can be converted in high yields into D-lysergic acid amide. 2. The morphological properties of this strain under different culture conditions are examined and it is shown that it grows in a form resembling natural sclerotia. 3. The biochemical culture conditions for the production of the new lysergic acid derivative in shake flasks and in stirred fermenters, the course of the fermentation, the methods for the isolation and purification of the substance and its transformation products and some of its chemical and physical properties are described.

Using a strain of Claviceps paspali Mar 488 it has been shown that alanine-2-C14 is incorporated with high efficiency in the carbinol amide moiety of D-Lysergic acid-α-hydroxyethylamide=II. After feeding of ᴅʟ-alanine-15N, DL-aspartic acid-15N and ʟ-glutamine-CO-15NH2 the highest specific incorporation rate was observed with DL-alanine-15N. Short term experiments with ᴅ,ʟ-alanine-15N revealed, that the greater part of the 15N-excess is localized in the N-atom of the side-chain of II. The carbinolamide moiety of the isolated alkaloid arises probably from alanine or a closely related compound.

Chemical changes in the mycelium of the conidial Claviceps paspali mutant strain, isolated after γ irradiation, were followed during the course of submerged fermentation and compared with the mycelial parent strain; both strains are capable of producing simple lysergic acid derivatives. The syntheses of lipids, carbohydrates, phosphates, nucleic acids, proteins, and alkaloids, as well as nutrient uptake, were determined. It was found that conidiation induced by mutagenic treatment was accompanied by a set of changes in the metabolic pattern. In the conidial mutant, the primary and secondary metabolic activities were repressed and the protein to nonprotein compound ratio of the cells was changed in favour of protein compounds.

The development of chemically defined media is a growing trend in in vitro embryo production (IVP). Recently, traditional undefined culture medium with bovine serum albumin (BSA) has been successfully replaced by a chemically defined medium using substances with embryotrophic properties such as platelet factor 4 (PF4). Although the use of this medium sustains IVP, the impact of defined media on the embryonic transcriptome has not been fully elucidated. This study analyzed the transcriptome of porcine IVP blastocysts, cultured in defined (PF4 group) and undefined media (BSA group) by microarrays. In vivo-derived blastocysts (IVV group) were used as a standard of maximum embryo quality. The results showed no differentially expressed genes (DEG) between the PF4 and BSA groups. However, a total of 2780 and 2577 DEGs were detected when comparing the PF4 or the BSA group with the IVV group, respectively. Most of these genes were common in both in vitro groups (2132) and present in some enriched pathways, such as cell cycle, lysosome and/or metabolic pathways. These results show that IVP conditions strongly affect embryo transcriptome and that the defined culture medium with PF4 is a guaranteed replacement for traditional culture with BSA.
