1. The production of a new lysergic acid derivative, identified as D-lysergic α -hydroxyethylamide, in submerged culture and yields up to 1 mg/ml. above, by strain Claviceps paspali Stevens & Hall is reported; this substance can be converted high into amide. 2. morphological properties under different conditions are examined it shown that grows form resembling natural sclerotia. 3. biochemical for the derivative shake flasks stirred fermenters, course fermentation, methods isolation...
The improved cleanup of marine oil spills by stimulating biodegradation through the use a slow-release fertilizer is reported. A paraffin-supported containing MgNH4PO4 as active ingredient was developed and evaluated in laboratory field experiments using quantitative infrared spectrometry chromatographic techniques. Sarir crude sea considerably enhanced fertilizer. After 21 days 63% had disappeared compared to 40% control area.
We study a duality between (infinitely generated) cotilting and tilting modules over an arbitrary ring. Dualizing result of Bongartz, we show that module P is partial iff direct summand C such the left Ext-orthogonal class ⊥P coincides with ⊥C. As application, characterize all torsion-free classes. Each defines lattice L = [Cogen P1P] Similarly, each P′ L′ [[Gen P′,P′⊥]] torsion Generalizing Assem Kerner, elements are determined by their Rejp-torsion parts, Trp-torsion-free parts.

The submerged culture production of ferroverdin, an iron-containing green pigment a novel type, by new species Streptomyces Wak. is reported. morphological properties this micro-organism are described, and the optimum conditions for pigmentation in shake flasks stirred fermenters determined. Preparation identification reductive alkali degradation products ferroverdin reported; on basis their structures it suggested that ferrous complex p -vinylphenylester 3-nitroso-4-hydroxybenzoic acid.
Let $T_R$ be a right $n$-tilting module over an arbitrary associative ring $R$. In this paper we prove that there exists $T'_R$ equivalent to which induces derived equivalence between the unbounded category $\D(R)$ and triangulated subcategory $\mathcal E_{\perp}$ of $\D(\End(T'))$ quotient modulo kernel total left functor $-\otimes^{\mathbb L}_{S'}T'$. case is classical module, get again Cline-Parshall-Scott Happel's results.
