Summary: This study investigates the deproteinization of shrimp waste and the production of alkaline protease enzyme by obligate alkalophilic Bacillus marmarensis. Optimum conditions for alkaline protease production are determined, and the highest protease activity is obtained from shrimp waste pretreated at specific conditions. B. marmarensis shows a capacity for deproteinization of shrimp waste and the production of alkaline proteases. The use of different carbon and nitrogen sources is also compared. Shrimp waste remains the best substrate for enzyme production. The results suggest that B. marmarensis can be used for sustainable bioprocesses using shrimp waste.

Summary: This research introduces a low-cost, non-commercial culture medium and optimizes the operating conditions for biological chitin extraction from green tiger shrimp waste in the Persian Gulf zone. The proposed culture medium shows higher efficiency in deproteinization and demineralization than the commercial medium. The optimization results indicate that the demineralization model is more complicated than the deproteinization model, and the presented model predicts the yields accurately. The extracted chitin exhibits similar functional groups and acetylation degree to shrimp shells, with good thermal stability.

Summary: This study assessed the biochemical and microbiological quality of shrimp pickle stored at room temperature and refrigerated temperature. The results showed that the pH remained below 5 throughout the six-month storage period, and all biochemical parameters were within acceptable limits. Sensory evaluation also indicated that the quality of the pickles was acceptable after six months of storage, with no significant difference between the two treatments.

Summary: A novel extracellular lignin peroxidase (LiP PR40) was produced by a white-rot Agaricomycetes fungus strain newly isolated from dead deciduous trees in Algeria. This purified enzyme showed premium activity at pH 3 and 80 degrees C, and exhibited higher catalytic efficiency and dye-decolorisation aptitude compared to commercial horseradish peroxidase and reported LiP BA45. These properties make LiP PR40 a potential candidate for destaining synthetic dyes and lignin biodegradation.

Summary: The present research aims to evaluate the variation of several responses in marine mussels exposed to different sub-lethal concentrations of copper and lead. The results showed that temperature and salinity variations were not significant enough to interfere with the effect of the pollutants. Changes in nitrogen and phosphorus mineral matter were found to be a physiological disturbance in both species. During the contamination cycles, catalase induction and protein depletion reflected the oxidative stress caused by the metals. However, the catalase activity returned to normal state during the decontamination cycles.

Summary: A novel extracellular lipase P22 from Penicillium crustosum Thom was isolated and characterized. The specific activities of P22 lipase were found to be 5000 and 10,000 U/mg on olive oil and trioctanoin emulsions, respectively. It exhibited clear regioselectivity toward the sn-1 position of surface-coated triglycerides and showed high activity and stability in the presence of water-immiscible organic solvents, surfactants, and oxidizing agents. It also showed compatibility with commercial laundry detergents and effectively removed oil stains.

Summary: The keratin-degrading bacterium Actinomadura viridilutea DZ50 secretes a keratinase (KERDZ) with potential industrial interest. Recombinant enzyme rKERDZ has been shown to completely degrade chicken feather and remove wool/hair from various hides, while preserving collagen structure. The enzymatic process reduces biological and chemical oxygen demands in leather processing and offers a greener alternative to traditional dehairing methods.
