Synthesis and Characterization of some New Amic acid and Imides and study the Biological Activity

open access: yesTikrit Journal of Pure Science, 2023
This study includs the synthesis of some new Amic acid and Imides, starting from the esters [S1] of Terephthalic acid which then converted to its hydrazide [S2] then to amic acid derivatives [S3-S7] and finally with imides [S8-S12].

Transcriptomic analyses reveal increased expression of dioxygenases, monooxygenases, and other metabolizing enzymes involved in anthracene degradation in the marine alga Ulva lactuca

open access: yesFrontiers in Plant Science, 2022
To analyze the mechanisms involved in anthracene (ANT) degradation in the marine alga Ulva lactuca, total RNA was obtained from the alga cultivated without ANT and with 5 μM of ANT for 24 h, and transcriptomic analyses were performed.

Comparative polymer biodegradation efficiency of an isolated Acinetobacter sp. with Bravibacillus sp. and E. coli by resting cells

open access: yesJournal of Advanced Biotechnology and Experimental Therapeutics, 2022
At a concentration of 4 g/L, an enteric polymer is utilized to target drug release in the small intestine and causes considerable toxicity in cells. Our ecology and ecosystem are also harmed by their non-biodegradable qualities.
