A degumming approach is used in this paper with alkalophilic pectinase-producing bacteria (APPB) and two sources of water solvents to address the existing conventional retting complexities kenaf. The incorporation APPB was confirmed based on their feasibilities multiple cell-wall-degrading enzymatic delicacy. combinations seawater offered achievements within six-day non-sterile conditions. Thes...

The binding energy and geometrical structure of all the possible dimeric systems of isothiocyanic acid (HNCS) with ozone have been investigated in the gas phase, theoretically. Six minima located on the singlet potential energy surface of the HNCS–ozone system at the MP2 level with binding energies (corrected with ZPE and BSSE) in the range 492.29–531.40 kcal/mol. All intermolecular interaction...

Pectinases are widely used in food processing, textile and other allied industries. Cassava peels generated from cassava processing outfits constitutes one of the major environmental pollutions Nigeria there is need to find alternative economic value waste instead indiscriminately disposing them as currently done. This study reports optimization pectinase production Bacillus subtilis PSE-8 usin...

Aspergillus spp. are widely spread plant pathogens. In several kinds of fruit, especially in apple and peach, aspergillus rot is one of the postharvest desease in fruit, but the infection mechanism is not known. The degradation of cell walls by pathogens is significant in primary infection and afterinfection, and plays an important role in the advancement of mycelium into the host plant and the...

As natural fibers, low-cost biosorbents have proven to be an effective and clean tool remove textile dyes from wastewater. In this research, the Reactive Black 5 removal ability of original enzyme-modified fibers were assessed. A fiber extracted a Colombian fique plant (Furcraea sp.) was employed. The effects protonation with different solvents dye solution pH on RB5 evaluated. biosorbent chemi...

Aluminum chalcogenides are mostly encountered in the form of bulk aluminum oxides that are structurally diverse but typically consist of networks with high lattice energy in which the chalcogen atoms bridge the metal centres. This makes their molecular congeners difficult to synthesize because of a pronounced tendency for oligomerization. Here we describe the isolation of the monotopic aluminum...

The research on secondary metabolites of Aspergillus lentulus afforded eight unusual heterodimeric tetrahydroxanthone derivatives, lentulins A-H (2-9), along with the known compound neosartorin (1). Compounds 1-6 exhibited potent antimicrobial activities especially against methicillin-resistant Staphylococci. Their absolute configurations, particularly the axial chiralities, were unambiguously ...

Genes coding for an endo-pectate lyase, an exo-pectate lyase, and an endopolygalacturonase of Erwinia carotovora subsp. carotovora Ecc71 were cloned in Escherichia coli HB101, using the cosmid pHC79. The products of the cloned pectinase genes paralleled their counterparts in strain Ecc71 in isoelectric mobility, mode of substrate degradation, and ability to macerate potato tuber tissue.

The structural chemistry of eleven donor complexes of the important Brønsted base potassium 1,1,1,3,3,3-hexamethyldisilazide (KHMDS) has been studied. Depending on the donor, each complex adopted one of five general structural motifs. Specifically, in this study the donors employed were toluene (to give polymeric 1 and dimeric 2), THF (polymeric 3), N,N,N',N'-tetramethylethylenediamine (TMEDA) ...
