Abstract
The present study was undertaken to biosynthesize zinc oxide nanoparticles (ZnONPs) using a mangrove-associated actinobacterium Streptomyces olivaceus (MSU3) under in vitro conditions. The synthesized ZnONPs were structurally characterized through UV, FT-IR, TG-DTA, XRD, SEM and EDX analysis. Analysis of biosynthesized ZnONPs in UV-Vis spectroscopy showed presence of functional groups between the wavelengths 325 and 380 nm. FT-IR analysis showed the functional groups, such as halo bromide (C-Br), alkyne (C≡C), carboxylic acid (O-H), nitro (N-O), fluoro (C-F), alkene (C=C) and aromatic (R-C-H) groups, respectively, within the wave numbers between 614.30 and 3074.41 cm-1. The crystalline poly-dispersed quasi spherical nature of ZnONPs expressed the average particle size of 37.9 nm with the 2θ values of 11.802-37.885°. Antibacterial activity of ZnONPs showed pronounced inhibitory zone (25 mm) and least MIC and MBC values (125 and 250 µg ml-1) against Escherchia sp. In the antifouling study, ZnONPs strongly inhibited byssal thread formation in mussel Perna indica and recorded LC50 value of 424.47 µg ml-1. Mollusc foot adherence assay inferred that the ZnONPs effectively inhibited settlement of limpet Patella vulgata and showed minimal fouling (26.43%) at 350 µg ml-1 and recorded LC50 value of 218.77 µg ml-1. Results of anticrustacean assay depicted that, ZnONPs had registered LC50 value of 676.08 µg ml-1 against Artemia salina nauplii. From this study, it could be concluded that an eco-friendly approach could be used to open a new avenue for biosynthesis of ZnONPs from a mangrove associated actinobacterium S. olivaceus (MSU3) in antifouling studies.

Abstract
Bio-surfactants are a principal group of significant molecules obtained from the microbial sources expressed with distinctive characteristics like biodegradation of hydrocarbons and also have different biomedical properties. The present investigation aims to assess the biomedical properties of synthesized bio-surfactant, rhamnolipid from Pseudomonas aeruginosa (DKB1) under in vitro conditions. The candidate bacterium P. aeruginosa (DKB1) was isolated from oil-polluted fishing harbors of Kanyakumari coast. Initially, the bio-surfactant production by this candidate strain was confirmed by oil displacement assay, hemolytic assay, drop collapse assay and emulsification index. Further, the production of bio-surfactant was achieved through submerged fermentation process using Bushnell-Haas mineral salts medium supplemented with 2% olive oil. The yield of the bio-surfactant was attained as 2.4 g/l and confirmed as rhamnolipid through blue agar plate assay; further, the extracted rhamnolipid was purified and characterized through standard procedures. In stability studies, the rhamnolipid could withstand up to pH 12, temperature 100 °C and 15% of NaCl concentration. The biomedical application of rhamnolipid (30 μg ml-1) was determined by antibacterial, antioxidant and cytotoxic studies. It exhibited a maximum growth inhibition against Bacillus subtilis (26 mm) with the MIC value of 8 μg ml-1. In antioxidant test, rhamnolipid expressed significant (P < 0.0001) inhibition of total reducing power (44.11%), DPPH activity (61.60%), hydroxyl radical (83.30%) and nitric oxide (51.86%) scavenging ability at 100 μg ml-1with the respective IC50 values of 130.50, 77.18, 52.08 and 95.43 μg ml-1. The anticancer activity of the rhamnolipid was assessed with the help of MTT test against MCF-7, HT-29 and E-143 cancer cell lines individually, and the viability of the cells was observed, respectively, as 10.24, 17.66 and 13.50% at 250 μg ml-1concentration with the respective IC50 values of 140.2, 81.02 and 138.9 μg ml-1. From the results, it could be concluded that the rhamnolipid produced by P. aeruginosa (DKB1) isolated from oil-polluted area has effective biomedical properties.

Abstract
The present study was undertaken to evaluate the biosynthesis, molecular modeling and statistical optimization of xylanase production through Box-Behnken design by a mangrove associated actinobacterium Streptomyces variabilis (MAB3). Initially, the production of xylanase by the selected strain was carried through submerged fermentation using birchwood xylan as substrate. Further the xylanase production was statistically optimized through Box-Behnken design. It showed 5.30 fold increase of xylanase production by the isolate compared to 'one factor at a time approach' in the presence of the basal medium containing birchwood xylan (2.0% w/v) at pH 8.2, temperature 46.5 °C, inoculum size of 2% for 68 h. The analysis of variance (ANOVA) revealed high coefficient of determination (R2 = 0.9490) for the respective responses at significant level (P < 0.0001). The xylanase was purified by different purification steps and it resulted 5.30 fold increase with the yield of 21.27% at the final step using sephadex G-75 chromatography. The molecular weight of the purified xylanase was observed as 50 kDa on 10% SDS-PAGE. The homology 3D structure of the purified xylanase protein was predicted and this protein encodes with 420 amino acid residues. The maximum activity of purified xylanase was observed at pH 8, temperature 40 °C and the production medium supplemented with 1 mM Ca2+ metal ion, 2.0% xylan and 1.5% NaCl. The kinetic parameters of the purified xylanase expressed the Km and Vmax values of 5.23 mg/ml and 152.07 μg/min/mg, respectively. Finally, the xylanolytic hydrolysis of pretreated agro-residues, especially the rice straw substituted medium yielded maximum (46.28 mg/g) level of reducing sugar and saccharification (63.18%), followed by bioethanol production (3.92 g/l) at 72 h of incubation. Based on the results, it could be confirmed that the selected isolate is a potent strain for xylanase production and also it can able to convert the pretreated agro-residues into economically important byproduct like bioethanol.

Abstract
Pharmacological properties of native carrageenan (κ) extracted from Kappaphycus alvarezii and commercial carrageenan (Sigma-Aldrich) were evaluated using in vitro antioxidant, anticancer and antidiabetic studies. Phytochemical analysis of native and commercial carrageenans showed the presence of alkaloids, saponins, steroids, gums & mucilages and carbohydrate. Both native and commercial carrageenans exhibited better antioxidant activities such as total antioxidant capacity (87±0.47 and 82.6±0.47μg A.A/g), hydroxyl radical scavenging activity (61.4±0.27 and 58.66±0.31μg/ml), nitric oxide radical scavenging activity (80.42±0.22 and 73.66±0.22μg/ml), DPPH radical scavenging activity (56.26±0.20 and 53.67±0.082μg/ml) and reducing power assay (46.57±0.32 and 42.54±0.27μg/ml) at the maximum concentration of 100μg/ml carrageenans. These results indicated that native carrageenan from K. alvarezii possessed better antioxidant potential in comparison with commercial carrageenan. Anticancer activities of both carrageenans showed excellent inhibition on the growth of breast, colon, liver and osteosarcoma cell lines at the maximum concentration of 150μg/ml. Native carrageenan exhibited an excellent anticancer activity on colon carcinoma cell lines (67.66±0.168%) with the IC50 value of 73.87μg/ml and commercial carrageenan possessed a potent inhibition on the growth of breast cancer cell lines (67.33±0.077%) with the IC50 value of 123.8μg/ml. These results clearly indicated the beneficial effect of native and commercial carrageenans as anticancer agents being a free radical scavenger. Anti-diabetic property of both carrageenans showed inhibition effect on α- glucosidase enzyme. The inhibitory effect depends on concentration of carrageenans and it was recorded that maximum (74.49±1.05 and 67.42±0.63) inhibitory effect of α- glucosidase enzyme at 500μg/ml concentration.
