Abstract
The fish processing industry generates a significant amount of waste, and the recycling of this waste is an issue of global concern. We sought to utilize the heads of cutlassfish (Trichiurus lepturus), which are typically discarded during processing, to produce peptone, which is an important source of amino acids for microbial growth and recombinant protein production. Cutlassfish head muscle (CHM) were isolated, and the optimal protease and reaction conditions for peptone production were determined. The resulting peptone contained 12.22 % total nitrogen and 3.19 % amino nitrogen, with an average molecular weight of 609 Da, indicating efficient hydrolysis of CHM. Growth assays using Escherichia coli have shown that cutlassfish head peptone (CP) supports similar or superior growth compared to other commercial peptones. In addition, when recombinant chitosanase from Bacillus subtilis and human superoxide dismutase were produced in E. coli, CP gave the highest expression levels among six commercial peptones tested. In addition, the expression levels of chitosanase and superoxide dismutase were 20 % and 32 % higher, respectively, in CP medium compared to the commonly used Luria-Bertani (LB) medium. This study demonstrates the potential of using cuttlassfish waste in the production of microbial media, thereby adding significant value to fish waste. The results contribute to sustainable waste management practices and open avenues for innovative uses of fish processing by-products in biotechnological applications.

Abstract
BACKGROUND Using fungal biomass for biocatalysis is a potential solution for the expensive cost of the use o enzymes. Production of fungal biomass with effective activity requires optimizing the cultivation conditions. RESULTS Rhizopus stolonifer biomass was optimized for transesterification and hydrolysis of waste frying oil (WFO). Growth and biomass lipolytic activities of R. stolonifer improved under shaking conditions compared to static conditions, and 200 rpm was optimum. As biomass lipase and transesterification activities inducer, olive oil was superior to soybean, rapeseed, and waste frying oils. Biomass produced in culture media containing fishmeal as an N-source feedstock had higher lipolytic capabilities than corn-steep liquor and urea. Plackett Burman screening of 9 factors showed that pH (5-9), fishmeal (0.25-1.7%, w/v), and KH2PO4 (0.1-0.9%, w/v) were significant factors with the highest main effect estimates 11.46, 10.42, 14.90, respectively. These factors were selected for response surface methodology (RSM) optimization using central composite design (CCD). CCD models for growth, biomass lipase activity, and transesterification capability were significant. The optimum conditions for growth and lipid modification catalytic activities were pH 7.4, fishmeal (2.62%, w/v), and KH2PO4 (2.99%, w/v). CONCLUSION Optimized culture conditions improved the whole cell transesterification capability of Rhizopus stolonifer biomass in terms of fatty acid methyl ester (FAME) concentration by 67.65% to a final FAME concentration of 85.5%, w/w.

Abstract
Filamentous fungi are microorganisms widely known for their diverse biochemical features. Fungi can efficiently invade a wide variety of substrates under operational conditions producing numerous bioproducts of interest, such as enzymes, organic acids, aromatic compounds and colorants. An additional interesting characteristic of some fungi is their safety classification for different uses, which guarantees that the bioproducts obtained from them do not contain any toxic component deleterious to humans. Rhizopus oryzae is among this group of fungi and is classified as a GRAS filamentous fungus, commonly used for production of some oriental traditional foods. It is mainly recognized as a good producer of lactic acid; however, its potential for other biotechnological processes is under study. This review analyzes and discusses the current scientific and technical contributions which may maximize the potential of R. oryzae as a producer of different compounds of industrial interest.

Abstract
The process parameters governing the production of fibrinolytic enzyme
in solid state fermentation employing Bacillus
cereus IND5 and using cuttle fish waste and cow dung substrate were
optimized. The pH value of the medium, moisture content, sucrose, casein and
magnesium sulfate were considered for two-level full factorial design and pH, casein
and magnesium sulfate were identified as the important factors for fibrinolytic
enzyme production. Central composite design was applied to investigate the
interactive effect among variables (pH, casein and magnesium sulfate) and response
surface plots were created to find the pinnacle of process response. The optimized
levels of factors were pH 7.8, 1.1% casein and 0.1% magnesium sulfate. Enzyme
production was increased 2.5-fold after statistical approach. The enzyme was
purified up to a specific activity of 364.5 U/g proteins and its molecular weight
was 47 kDa. It was stable at pH 8.0 and was highly active at 50 °C. The mixture of
cuttle fish waste and cow dung could find great application as solid substrate for
the production of fibrinolytic enzyme.

Abstract
Fish meal has been used as an additional nitrogen source and fish oil as inducer for the growth and production of lipase from Cryptococcus sp. MTCC 5455. A response surface design illustrated that the optimum factors influencing lipase production were fish meal, 1.5 %, w/v, Na2HPO4, 0.2 %, w/v, yeast extract, 0.25 %, w/v and sardine oil, 2.0 %, w/v with an activity of 71.23 U/mL at 96 h and 25 °C, which was 48.39 % higher than the conventional one-factor-at-a-time method. The crude concentrated enzyme hydrolyzed polyurethane (PUR) efficiently and hydrolysis was 94 % at 30 °C and 96 h. The products, diethylene glycol and adipic acid were quantified by HPLC and scanning electron microscopic studies of the degraded polymer showed significant increase in size of the holes from 24 to 72 h of incubation. Hydrolysis of PUR within 96 h makes the lipase novel for disposal of PUR and provides an innovative solution to the problems created by plastic wastes.

Abstract
Fishery processing industries generate large amounts of by-products. The disposal of these wastes represents an increasing environmental and health problem. To avoid wasting these by-products, various disposal methods have been applied including, ensilation, fermentation, hydrolysate and fish oil production. Interestingly, fish by-products provide an excellent nutrient source for microbial growth useful in enzyme production process, which is largely governed by the cost related to the growth media. Fish wastes (heads, viscera, chitinous material, wastewater, etc.) were prepared and tested as growth substrates for microbial enzymes production such as protease, lipase, chitinolytic and ligninolytic enzymes. This new approach described in this review can reduce environmental problems associated with waste disposal and, simultaneously, lower the cost of microbial enzyme production.

Abstract
Lipase production by Staphylococcus xylosus and Rhizopus oryzae was investigated using a culture medium based on a mixture of synthetic medium and supernatants generated from tuna by-products and Ulva rigida biomass. The proportion of the three medium components was optimized using the simplex-centroid mixture design method (SCMD). Results indicated that the experimental data were in good agreement with predicted values, indicating that SCMD was a reliable method for determining the optimum mixture proportion of the growth medium. Maximal lipase activities of 12.5 and 23.5 IU/mL were obtained with a 50:50 (v:v) mixture of synthetic medium and tuna by-product supernatant for Staphylococcus xylosus and Rhizopus oryzae, respectively. The predicted responses from these mixture proportions were also validated experimentally.

Abstract
By-products from different animal sources are currently being utilised for beneficial purposes. Chicken processing plants all over the world generate large amount of solid by-products in form of heads, legs, bones, viscera and feather. These wastes are often processed into livestock feed, fertilizers and pet foods or totally discarded. Inappropriate disposal of these wastes causes environmental pollution, diseases and loss of useful biological resources like protein, enzymes and lipids. Utilisation methods that make use of these biological components for producing value added products rather than the direct use of the actual waste material might be another viable option for dealing with these wastes. This line of thought has consequently led to researches on these wastes as sources of protein hydrolysates, enzymes and polyunsaturated fatty acids. Due to the multi-applications of protein hydrolysates in various branches of science and industry, and the large body of literature reporting the conversion of animal wastes to hydrolysates, a large section of this review was devoted to this subject. Thus, this review reports the known functional and bioactive properties of hydrolysates derived from chicken by-products as well their utilisation as source of peptone in microbiological media. Methods of producing these hydrolysates including their microbiological safety are discussed. Based on the few references available in the literature, the potential of some chicken by-product as sources of proteases and polyunsaturated fatty acids are pointed out along with some other future applications.

Abstract
Media composition and culture conditions for surfactant stable alkaline protease production by Bacillus mojavensis A21 were optimized using two statistical methods. Plackett-Burman design was applied to find the optimal ingredients and conditions to improve yields. Response surface methodology (RSM), including central composite design, was used to determine the optimal concentrations and conditions. The results indicated that several components, including hulled grain of wheat (HGW), sardinella peptone (SP), NaCl, CaCl(2), MgSO(4), K(2)HPO(4), KH(2)PO(4), agitation, culture temperature and initial medium pH, had significant effects on production. The statistical model was constructed via central composite design (CCD) using four selected variables (HGW, NaCl, KH(2)PO(4) and K(2)HPO(4)). Under the proposed optimized conditions, the protease experimental yield (1860.63U/mL) closely matched the yield predicted by the statistical model (1838.60U/mL) with R(2)=0.98. An overall 14.0-fold increase in protease production was achieved using the optimized medium (HGW 30.0g/L, SP 1.0g/L, NaCl 2.0g/L, KH(2)PO(4) 1.0g/L, K(2)HPO(4) 0.3g/L, CaCl(2) 2.0g/L, MgSO(4) 1.0g/L and pH 9.0, compared with the unoptimized basal medium (starch 10.0g/L, yeast extract 2.0g/L, KH(2)PO(4) 0.1g/L, K(2)HPO(4) 0.1g/L, CaCl(2) 0.5g/L and pH 8.0; 137U/mL). A successful and significant improvement (14-fold) in the production of protease by the A21 strain was accomplished using cheap carbon and nitrogen substrates (HGW and SP), which may result in a significant reduction in the cost of medium constituents.

Abstract
Experiments were conducted using the crude protein in fresh dairy manure as the nitrogen source in the culture media for Rhizopus oryzae to produce L-lactic acid. Two uniform design experiments were carried out with one for optimizing seed culture while the other for best percent L-lactic acid production. Multiple linear regression and ANOVA analyses were employed to determine the most significant media components. Data from the first uniform design U6 (6(2)x 3), in which the experimental factors involved included nitrogen concentration (crude protein), spore concentration, and treatment duration, showed that the levels of these components in the optimal condition for the seed culture medium were 2.1 g/L nitrogen, 16 hour culture time, and 10(5) spore concentration. The biomass weight in the seed medium developed in this study reached 1.32 g/L, which was 48.3% higher than that of the control. The combination of culture time and nitrogen concentration was found to be most significant in influencing the biomass yield. In the second uniform design experiment, flask culture with five factors (glucose, nitrogen from dairy manure, ZnSO4, KH2PO4, and MgSO4) at eight levels was examined using the uniform design table U8 (8(5)) with the content of L-lactic acid as the evaluating response Y. The results showed that ZnSO4 had the most influence on L-lactic acid yield, followed by nitrogen and KH2PO4. The optimum culture medium in terms of lactic acid production consisted of 240 g/L glucose, 1.26 g/L crude protein, 1.05 g/L KH2PO4, and 0.25 g/L MnSO4, which could achieve a yield of 59.57% (7.1% higher than the control).

Abstract
Extracellular lipase production by Staphylococcus epidermidis CMST Pi 2 isolated from the intestine of shrimp Penaeus indicus has been investigated in shake-flask experiment using different preparations of tuna-processing waste such as raw fish meat, defatted fish meat, alkali hydrolysate, and acid hydrolysate as nitrogen source. Among the tested tuna preparations, defatted fish meat supported the maximum lipase production, and 2.5% concentration of the same was found to be optimum for maximizing the lipase production. The effect of carbon sources on lipase production revealed that glucose aided the higher lipase production than any other tested carbon source and a concentration of 2% glucose registered as optimum to enhance the lipase production. The halotolerancy of S. epidermidis CMST Pi 2 for lipase production indicated that 4% of sodium chloride was optimum to yield maximum lipase. Among the surfactants tested, lipase production was high in Tween 20 added medium when compared to other surfactants, and its optimum concentration recorded was 0.8%. Partial characterization of crude enzyme revealed that pH 7 and 55 degrees C temperature were optimum for maximum lipase activity.

Souissi N, Ellouz-Triki Y, Bougatef A, Blibech M, Nasri M. Preparation and use of media for protease-producing bacterial strains based on by-products from Cuttlefish (Sepia officinalis) and wastewaters from marine-products processing factories. Microbiol Res 2008; 163:473-80. [PMID: 16962303 DOI: 10.1016/j.micres.2006.07.013] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2006] [Revised: 05/16/2006] [Accepted: 07/07/2006] [Indexed: 11/24/2022]
Abstract
Cuttlefish powder (CFP) from Sepia officinalis by-products was prepared and tested as a fermentation substrate for microbial growth and protease production by several species of bacteria: Bacillus licheniformis, Bacillus subtilis, Pseudomonas aeruginosa, Bacillus cereus BG1, and Vibrio parahaemolyticus. All microorganisms studied grew well and produced protease activity when cultivated in medium containing only CFP indicating that the strains can obtain their carbon and nitrogen source requirements directly from whole by-product proteins. Moreover, it was found that the addition to the cuttlefish medium of diluted fishery wastewaters (FWW), generated by marine-products processing factories, enhanced the production of protease. Maximum activity was obtained when cells were grown in cuttlefish media containing 5-times or 10-times diluted FWW. Five-times diluted FWW enhanced protease production by B. cereus BG1 and B. subtilis by 467% and 75% more than control media, respectively. The enhancement could have been due to the high organic content or high salts in FWW. As a result, cuttlefish by-products powder enriched with diluted FWW was found to be a suitable growth media for protease-producing strains. This new process, which converts underutilized wastes (liquid and solid) into more marketable and acceptable forms, coupled with protease production, can be an alternative way to the biological treatment of solid and liquid wastes generated by the cuttlefish processing industry.

Abstract
Fishmeal wastewater, a seafood processing waste, was utilized for production of lactic acid and fungal biomass by Rhizopus oryzae AS 3.254 with the addition of sugars. The 30 g/l exogenous glucose in fishmeal wastewater was superior to starch in view of productivities of lactic acid and fungal biomass, and COD reduction. Fishmeal wastewater can be a replacement for peptone which was the most suitable nitrogen source for lactic acid production among the tested organic or inorganic nitrogen sources. Exogenous NaCl (12 g/l) completely inhibited the production of lactic acid and fungal growth. In the medium of COD 5,000 mg/l fishmeal wastewater with the addition of 30 g/l glucose, the maximum productivity of lactic acid was 0.723 g/l h corresponding to productivity of fungal biomass 0.0925 g/l h, COD reduction 84.9% and total nitrogen removal 50.3% at a fermentation time of 30 h.
