Yemen with its diverse climatic regions represents a rich resource for bioactive compounds obtained from microorganisms. This study was designed to screen fungal isolates obtained from the Microbiology branch, Biological Sciences Department, Faculty of Science, Sana’a University for their ability to produce L-asparaginase enzyme. In preliminary screening for L-asparaginase, among 77 fungal isolates about 29 fungal isolates representing 37.66% were high producers of L-asparaginase. These fungal isolates belonged to the genera Aspergillus, Eupenicillium, Fusarium, Penicillium, and Stachyobotrys. These 29 fungal isolates were screened for their ability to produce L-asparaginase using the agar well diffusion method. 12 fungal isolates out of 29 showed the ability to produce extracellular L-asparaginase. These isolates belonged to 8 species which were: A. sulphurs, A. ustus, F. sacchari, P. chrysogenum, P. citrinum, P. corylophilum, P. melinii, and P. subturcoseum. Only 5 isolates were obtained for the determination of enzymatic activity, among them P. chrysogenum showed the highest activity (279.8696U ml-1) followed by A. ustus (170.9435U ml-1). This finding is the first report on the L-asparaginase production from filamentous fungi in Yemen.

Publishing with the International Journal of Clinical and Experimental Ophthalmology was a rewarding experience as review process was thorough and brisk.
Their visibility online is second to none as their published articles appear in all search engines.
I will encourage researchers to publish with them.

In 2017, I submitted a manuscript to the journal Archives of Biotechnology and Biomedicine belonging to Heighten Science Publications Corporation. Within one week I already received the response from the editor. All processing steps were really fast so in terms of a speedy publication I can particularly recommend the journal Archives of Biotechnology and Biomedicine. The responsible contact person of the journal was always available, which gives a trustworthy impression to the author. Also the peer review process was clear and constructive. So from my experience with Heighten Science Publications Corporation I can recommend publishing there.

“The choice to submit the forensic case study to the Journal of Addiction Therapy and Research was dictated by the match between the content and the potential readership. The publication process proved to be expedient and we were provided with constructive feedback from reviewers. The final article layout is attractive and conforms to standards. All-in-all, it has been a rewarding process.”
