From a strain of Bacillus subtilis a new antifungal peptidolipid complex of the iturin group was isolated. This antibiotic complex contained six lipophilic beta-amino acids with 3-amino-14-methylpentanoic acid as the predominant component. Iturin AL contains: 2 D-Asp, 1 L-Asp, 1 L-Glu, 1 L-Pro, 1 L-Ser, 1 D-Tyr and a mixture of 2.9% iso-C14-beta-amino acid, 30.7% n-C14-beta-amino acid, 15% iso-...

A strictly anaerobic bacterial strain, 7401987T, was isolated from a human brain abscess sample. Cells were Gram-negative, non-spore-forming, coccoid to rod-shaped and motile by flagella in a lophotrichous arrangement. The isolate was asaccharolytic and the major cellular fatty acids were anteiso-C15:0 (28.2%), C16:0 (18.0%), iso-C15:0 (12.3%) and iso-C17:0 3-OH (11.7%). 16S rRNA gene sequence ...

In bacteriorhodopsin, the order of molecular events that control the cytoplasmic or extracellular accessibility of the Schiff bases (SB) are not well understood. We use molecular dynamics simulations to study a process involved in the second accessibility switch of SB that occurs after its reprotonation in the N intermediate of the photocycle. We find that once protonated, the SB C15 = NZ bond ...

The objectives of this study were to evaluate changes in profiles odd- and branched-chain fatty acids (OBCFA), including pentadecanoic acid (C15:0), 13-methyltetradecanoic ( iso -C15:0), 12-methyltetradecanoic anteiso 14-methylpentadecanoic -C16:0), heptadecanoic (C17:0), 15-methylhexadecanoic -C17:0), 14-methylhexadecanoic -C17:0) during vitro fermentation pure carbohydrates mixtures the buffe...

Originating from deoxygenation (DO) technology, green diesel was innovated in order to act as a substitute for biodiesel, which contains unstable fatty acid alkyl ester owing the existence of oxygenated species. Green manufactured following process catalytic DO sludge palm oil (SPO). An engineered Mn(0.5%)-Mo(0.5%)/AC catalyst employed hydrogen-free atmosphere. The influence Manganese (Mn) spec...

The strength of concrete is determined by its compressive strength. SNI 2847-2013 has that the obtained using a cylindrical specimen with diameter 15 and height 30 cm (C.15) or 10 20 (C.10) at 28 days age. problem commonly encountered in field how to estimate acceptable if it not reached age specimens do meet standards set out SNI. This study aims obtain correction factor for shape test object ...

The interactions of epothilone analogs with the paclitaxel binding site of microtubules were studied. The influence of chemical modifications in the C15 side chain and in C12 on binding affinity and microtubule elongation was characterized. Modifications favorable for binding affinity are (1). a thiomethyl group at C21 of the thiazole side chain, (2). a methyl group at C12 in S configuration, (...

Three new sesquiterpene glycosides, named codonopsesquilosides A-C (1-3), were isolated from an aqueous extract of the dried roots of Codonopsis pilosula. Their structures including absolute configurations were determined by spectroscopic and chemical methods. These glycosides are categorized as C15 carotenoid (1), gymnomitrane (2), and eudesmane (3) types of sesquiterpenoids, respectively. Com...

A total of 1540 bacterial isolates were isolated and screened for their ability to degrade selected azo dyes. Of these, nine isolates were chosen for further studies based on their ability to degrade a wide spectrum of dyes efficiently and rapidly. Several microbial consortia were developed and tested for their effectiveness. Overall the consortia were able to degrade 70 100% colour within 72 h...
