Optimized production and characterization of a thermostable cellulase from Streptomyces thermodiastaticus strain.

A high cellulase-producing bacterial isolate TS4 was recovered from an Egyptian soil sample and identified using 16S rRNA gene sequencing as Streptomyces thermodiastaticus. One-factor-at-a-time (OFAT) preliminary studies were carried out to determine the key factors affecting cellulase production by S. thermodiastaticus and their optimum ranges.

Scaling up production of cephalosporin C by Acremonium chrysogenum W42-I in a fermenter using submerged fermentation.

Cephalosporins presently stand as the most extensively utilized antibiotic in clinical settings. Acremonium (A.) chrysogenum is the main strain used in the manufacturing of cephalosporin C (CPC), which offers distinct advantages, including a wide-ranging antibacterial spectrum and powerful antibacterial efficacy.

Statistical optimization and gamma irradiation on cephalosporin C production by Acremonium chrysogenum W42-I.

Most antibiotics now used in clinical practice are cephalosporins. Acremonium (A.) chrysogenum W42-I is an intermediate strain out of W42 strain improvement program whose productivity is above that of the wild-type strain to produce the broad-spectrum antibacterial cephalosporin C (CPC).

The gametogenic cycle and spawning of the short-necked clam, Paphia undulata Born, 1778 (Bivalvia: Veneridae) from Timsah Lake, Suez Canal, Egypt.

Background: Paphia undulata, The Short-Necked Clam, is an edible marine bivalve that is consumed internationally and locally in Egypt. Overfishing and pollution have caused population declines in Egyptian fisheries during the last decade. Accurate reproductive biology knowledge is critical for designing long-term exploitation strategy for this resource.
