Jellyfish protein hydrolysates: Multifunctional bioactivities unveiled in the battle against diabetes, inflammation, and bacterial pathogenesis.

This study investigates the multifunctional bioactivities of pepsin-hydrolyzed jellyfish by-products (Rhopilema hispidum and Lobonema smithii), focusing on their anti-α-glucosidase activity, anti-inflammatory effects, anti-bacterial properties, and ability to inhibit biofilm formation of Staphylococcus aureus. Our findings revealed that jellyfish protein hydrolysates, particularly from Rhopilema hispidum, exhibit significant anti-α-glucosidase activity, surpassing the well-known α-glucosidase inhibitor Acarbose. Furthermore, we demonstrated the anti-inflammatory capabilities of these hydrolysates in suppressing lipopolysaccharide (LPS)-induced nitric oxide production in murine macrophage cells.

Study of marine microorganism metabolites: new resources for bioactive natural products.

The marine environment has remained a source of novel biological molecules with diversified applications. The ecological and biological diversity, along with a unique physical environment, have provided the evolutionary advantage to the plant, animals and microbial species thriving in the marine ecosystem. In light of the fact that marine microorganisms frequently interact symbiotically or mutualistically with higher species including corals, fish, sponges, and algae, this paper intends to examine the potential of marine microorganisms as a niche for marine bacteria.

Marine microbial alkaline protease: An efficient and essential tool for various industrial applications.

With the modern world focusing on environmental friendly products, more and more chemical processes are being replaced by enzymatic methods. Alkaline proteases (APases) place more than 50% of the total world enzyme production. Marine microorganisms are capable of producing an extensive spectrum of APases which have important ecological roles and promising industrial applications.

Metabolites from Marine Microorganisms, Micro, and Macroalgae: Immense Scope for Pharmacology.

Marine organisms produce a large array of natural products with relevance in drug discovery. These compounds have biological activities such as antioxidant, antibacterial, antitumor, antivirus, anticoagulant, anti-inflammatory, antihypertensive, antidiabetic, and so forth. Consequently, several of the metabolites have made it to the advanced stages of clinical trials, and a few of them are commercially available.

Marine bacterial chitinase as sources of energy, eco-friendly agent, and industrial biocatalyst.

Chitin is the richest renewable polymer carbohydrate in the marine environment and is an energetic source of nitrogen and carbon for marine organisms. Marine chitinolytic bacteria play a basic role in the nutrient cycling in the oceans by biodegradation of chitinous waste to useful form. Chitinase-producing bacteria from marine wastes increasing attention has received, and it serves two purposes: (i) reduce environmental hazards by waste management and (ii) increases generation of industrially important value-added products.

Future direction in marine bacterial agarases for industrial applications.

The marine ecosystem has been known to be a rich source of novel enzymes. Agarase is a key enzyme that can hydrolyze agar in the marine environment. Marine bacterial agarase has been isolated from various sources, such as sediments, coastal water, and deep sea and from the surface of crustaceans and seaweeds.

Thermostable marine microbial proteases for industrial applications: scopes and risks.

Thermostable proteases are important in biotechnological and industrial sectors, due to their stability against denaturing agents and chemicals. The feature that gives them such unique applicability is their reaction at high temperatures, which affords a high concentration of substrate, and less risk of microbial contamination. Nearly 65% of industrial proteases are isolated from marine microbial source, and they can significantly resist a wide range of organic solvents at high temperatures.
