“…The enzyme activity was approximately increased 1.64-fold from that of the unoptimized condition (126.8 ± 0.047 U/mL) (Cahyaningtyas et al 2021). The level of protease activity in our study was higher than that of the same species in previous literature, such as B. cereus isolated from soil (9.56 U/mL) (Özgür and Nilüfer 2011), B. cereus FT1 (187 U/mL) (Asha and Palaniswamy 2018), and obviously greater than that of other species, Alcaligenes faecalis SK10 (58.74 U/mL) (Pal et al 2021), Paenibacillus sp.

Chitin extraction from shrimp shell powder (SSP) using protease-producing microbes is an attractive approach for valorizing shrimp shell waste because it is simple and environmentally friendly. In this study, the protease production and chitin extraction from SSP by Bacillus cereus HMRSC30 were simultaneously optimized using statistical approaches. As a result, fermentation in medium composed of 30 g/L SSP, 0.2 g/L MgSO 4 · 7H 2 O, 3 g/L (NH 4 ) 2 SO 4 , 0.5 g/L K 2 HPO 4 , and 1.5 g/L KH 2 PO 4 (pH 6.5) for 7 days maximized protease production (197.75 ± 0.33 U/mL) to approximately 1.64-fold compared to unoptimized condition (126.8 ± 0.047 U/mL). This level of enzyme production was enough to achieve 97.42 ± 0.28% deproteinization (DP) but low demineralization (DM) of 53.76 ± 0.21%. The high DM of 90% could be easily accomplished with the post-treatment using 0.4 M HCl and acetic acid. In addition, the study evaluated the possible roadmap to maximize the value of generated products and obtain additional profits from this microbial process. The observation showed the possibility of serving crude chitin as a bio-adsorbent with the highest removal capacity against Coomassie brilliant blue (97.99%), followed by methylene blue (74.42%). The recovered protease exhibited the function to remove egg yolk stain, indicating its potential for use as a detergent in de-staining. The results corroborated the benefits of microbial fermentation by B. cereus HMRSC30 as green process for comprehensive utilization of shrimp shell waste as well as minimizing waste generation along the established process.

“…Microbial bioconversion of shrimp and crab shell wastes was attempted using a chitinase-producing Alcaligenes faecalis SK10 strain and assessed for its potential as fertiliser on the growth of growth of Pisum sativum and Cicer arietinum . When compared to fertiliser doses of raw chitin, the fermented hydrolysate showed performances on par for several parameters such as micronutrient content (NPK) of soil, plant growth, and chlorophyll content [ 82 ]. A marine bacterium Exiguobacterium antarcticum DW2 was found to produce a cold-temperature chitinase that hydrolyzes chitin to bioactive polysaccharides [ 141 ].…”

The plant-microbe holobiont has garnered considerable attention in recent years, highlighting its importance as an ecological unit. Similarly, manipulation of the microbial entities involved in the rhizospheric microbiome for sustainable agriculture has also been in the limelight, generating several commercial bioformulations to enhance crop yield and pest resistance. These bioformulations were termed biofertilizers, with the consistent existence and evolution of different types. However, an emerging area of interest has recently focused on the application of these microorganisms for waste valorization and the production of “bio-organic” fertilizers as a result. In this study, we performed a bibliometric analysis and systematic review of the literature retrieved from Scopus and Web of Science to determine the type of microbial inoculants used for the bioconversion of waste into “bio-organic” fertilizers. The Bacillus, Acidothiobacillus species, cyanobacterial biomass species, Aspergillus sp. and Trichoderma sp. were identified to be consistently used for the recovery of nutrients and bioconversion of wastes used for the promotion of plant growth. Cyanobacterial strains were used predominantly for wastewater treatment, while Bacillus, Acidothiobacillus, and Aspergillus were used on a wide variety of wastes such as sawdust, agricultural waste, poultry bone meal, crustacean shell waste, food waste, and wastewater treatment plant (WWTP) sewage sludge ash. Several bioconversion strategies were observed such as submerged fermentation, solid-state fermentation, aerobic composting, granulation with microbiological activation, and biodegradation. Diverse groups of microorganisms (bacteria and fungi) with different enzymatic functionalities such as chitinolysis, lignocellulolytic, and proteolysis, in addition to their plant growth promoting properties being explored as a consortium for application as an inoculum waste bioconversion to fertilizers. Combining the efficiency of such functional and compatible microbial species for efficient bioconversion as well as higher plant growth and crop yield is an enticing opportunity for “bio-organic” fertilizer research.

“…Agrochemicals such as fertilizers and pesticides have revolutionized modern agriculture by increasing crop yield, fighting pests and diseases, and improving crop varieties (Hillel 2008 ). However, these chemicals are one of the leading causes of soil, water, and air pollution (Akhtar and Mannan 2020 ; Pal et al 2021 ). Furthermore, agrochemicals like fertilizers can contribute the climate change and global warming as they release greenhouse gases like nitrous oxide (Yadav et al 2021 ).…”

“…Using SW extract enhanced the glucosinate content in broccoli and increased the yield compared to the broccoli plants that were unfertilized or fertilized with sheep manure (Øvsthus et al 2015 ). Chitin, predominantly present in SW, is rich in nitrogen, phosphorus, calcium, and other vital nutrients necessary for plant growth (Fatima et al 2018 ; Pal et al 2021 ). Applying chitin obtained from SW as a biofertilizer improved the growth of potatoes and wheat compared to the plants treated with chemical fertilizer (Fatima et al 2018 ).…”

“…However, obtaining the chitin from SW to be used as fertilizer can be hazardous to the environment due to the extensive use of strong acids and alkalis. An approach to overcome this limitation can be the fermentation of the SW by microbes producing protease and chitinase and applying the fermented hydrolysate as a biofertilizer (Pal et al 2021 ). The fermented hydrolysate produced by the fermentation of shrimp shell powder by Alcaligenis faecalis SK10 has been used as a biofertilizer in Cicer arietinum and Pisum sativum (Pal et al 2021 ).…”

The seafood industry generates waste, including shells, bones, intestines, and wastewater. The discards are nutrient-rich, containing varying concentrations of carotenoids, proteins, chitin, and other minerals. Thus, it is imperative to subject seafood waste, including shrimp waste (SW), to secondary processing and valorization for demineralization and deproteination to retrieve industrially essential compounds. Although several chemical processes are available for SW processing, most of them are inherently ecotoxic. Bioconversion of SW is cost-effective, ecofriendly, and safe. Microbial fermentation and the action of exogenous enzymes are among the significant SW bioconversion processes that transform seafood waste into valuable products. SW is a potential raw material for agrochemicals, microbial culture media, adsorbents, therapeutics, nutraceuticals, and bio-nanomaterials. This review comprehensively elucidates the valorization approaches of SW, addressing the drawbacks of chemically mediated methods for SW treatments. It is a broad overview of the applications associated with nutrient-rich SW, besides highlighting the role of major shrimp-producing countries in exploring SW to achieve safe, ecofriendly, and efficient bio-products.
