Abstract
In the present study, the soil samples were collected from marine environment of Arichalmunai, Dhanushkodi, Ramnad District, Tamilnadu ,India. Fungal species were isolated by plating method, in 50% sea water containing potato dextrose agar medium .Totally 16 fungal species were isolated and identified from the soil sample. The production of protease from Aspergillus niger , A.flavus and A. terreus by liquid state fermentation. The production of protease enzyme was optimized by using fermentation medium containing different substrates. The maximum protease production was observed on wheat bran, containing medium. The protease production was maximum in temperature 35ºC were recorded. Wheat bran produced the maximum level protease. The optimization work also carried out. This study revealed that coastal environment provides impressive density of fungi in the East Coast of India and are unexplored for microbial resources can be useful in industry.

Abstract
Ophthalmic infections can cause damage to the structure of the eye which can lead to vision loss and blindness if left untreated. Ophthalmic infection or eye infections are caused by exposure to bacterial, fungal viral and protozoan are common with frequently reported in Asian countries. In the present study, the external ocular infected samples collected from Thanjavur Medical College Hospital, Thanjavur. Seven strains were isolated from the external ocular infected samples and identified a standard manual of Determinative Bacteriology by Bergy’s manual 12th edition. The commercial antibiotics and eye drops tested against Bacillus cereus, B. subtilis, Escherichia coli, Klebsiella sp. Pseudomonas sp. Streptococcus sp. and Staphylococcus aureus. The majority of the isolates were sensitive to tobramycin followed by moxifloxacin, gatifloxacin and ofloxacin. The resistant antibiotics are ciprofloxin and sensitive antibiotic was ampicillin was recorded with respective bacteria.

Abstract
Bacillus cereus is a gram-positive, anaerobic, spore-forming bacterium related to food poisoning in humans. Vomit and diarrhea are the symptoms of foodborne B. cereus infection caused by emetic toxins and three enterotoxins, respectively. This bacterium is broadly present in soil and foods such as vegetables, spices, milk, and meat. The antibiotics impenem, vancomycin, chloramphenicol, gentamicin, and ciprofloxacin are used for all susceptible strains of B. cereus. But these antibiotics cause side effects in the host due to the drug-host interaction; because the targeted proteins by the drugs are not pathogen specific proteins, they are similar to human proteins also. To overcome this problem, this study focused on identifying putative drug targets in the pathogen B. cereus and finding new drugs to inhibit the function of the pathogen. The identification of drug targets is a pipeline process, starting with the identification of targets non-homologous to human and gutmicrobiota proteins, finding essential proteins, finding other proteins that highly interact with these essential proteins that are also highly important for protein network stability, finding cytoplasmic proteins with a clear pathway and known molecular function, and finding non-druggable proteins. Through this process, two novel drug targets were identified in B. cereus. Among the various antibiotics, Gentamicin had showed good binding affinity with the identified novel targets through molecular modeling and docking studies using Prime and GLIDE module of Schrödinger. Hence, this study suggest that the identified novel drug targets may very useful in drug therapeutic field for finding inhibitors which are similar to Gentamicin and designing new formulation of drug molecules to control the function of the foodborne illness causing pathogen B. cereus.

Abstract
To evaluate phytochemical constituents from the methanolic extracts of medicinal plants Aloe castellorum and Aloe pseudorubroviolacea. The cytotoxic activity of Aloe castellorum and Aloe pseudorubroviolacea leaf extracts against Human colon cancer cell line (HCT-116) was also assessed. The two medicinal plant extracts having significant cytotoxic activity, meanwhile the methanolic extract of Aloe castellorum shows higher cytotoxic activity than Aloe pseudorubroviolacea extract. The Aloe castellorum shows remarkable activity against respective cell line than control. The characteristic chemical constituents of Aloe castellorum and Aloe pseudorubroviolacea leaf extracts were recognized from Gas chromatography and Mass spectrometry (GC–MS) technique. The molecular docking studies also support the cytotoxic activity.
