The marine fungi occurring on the wood samples were studied. Diversity of marine fungi colonizing the lignicolous wood samples was assessed and their distribution pattern was determined. The antibacterial activity of Aspergillus oryzae was tested against five human pathogens by agar well diffusion method. Based on the results, the compounds were separated by Thin Layer Chromatography (TLC) and these compounds were tested against three human bacterial pathogens. The separated compounds were further analyzed by Fourier Transform Infrared Spectroscopy (FTIR) to identify the functional groups, for the antibacterial activity.Keywords

The soil sample was collected from the salt pan of Bay of Bengal at Vedaranyam,Nagapattinam (Dt.) Tamilnadu, India. The physico-chemical parameters at the sample were analyzed by using standard procedures.Totally 10 actinomycetes were isolated and identified from the salt pan soil sample. Two actinomycetes namely Jonesia denitrificans and Nocardia amarae were dominant in their growth out of 10 isolated actinomycetes.
Antibacterial activity of Jonesia denitrificans and Nocardia amarae were studied against five human bacterial pathogens such as Salmonella typhi, Bacillus subtilis, Staphylococcus aureus, Vibrio cholerae and Klebsiella pneumonia. The acetone extract of Nocardia amarae exhibited promising antibacterial activity against Bacillus subtilis (25 mm). The isolation, characterization and the study on actinomycetes can be useful in the discovery of antibiotics.

Alcaligenes eutrophus was collected from MTCC bank and purity was checked according to the guidelines of Bergey's manual of bacteriology. The PHB production ability of the culture was tested by "Granular stains method". The test organism was grown in synthetic and various industrial waste based medium (Molasses, seasame oil waste) at different concentration (10%, 20%, 30% and 40%).The PHB producer grown in synthetic and various industrial waste based medium and PHB was extracte and estimated by using UV spectrophotometer. The pure form of PHB powder was collected and studied by Infrared analysis. In the present study, the high PHB production was seen in Alcaligenes eutrophus grown in 40% concentration of seasame oil waste when compared with other substrate and synthetic medium. The present study concludes that the seasame oil waste based medium and Alcaligenes eutrophus used for PHB production in large scale that minimize the cost of the product. Thus we can minimize the use of petroleum-derived plastics and by which we can live in a plastic pollution free earth.Keywords

The learn of Sphaeranthus amaranthoides Burn, were examined for their antioxidant, antimutagenic, antimicrobial and phytochemical activities. Preliminary evaluation of both crude and solvent fractions showed a broad spectrum of activity since the extracts inhibit the growth of both bacterial and fungal isolates. The inhibitory activity of plant extracts on the peroxidation of linolic acid were measured by fericthiocynate methodo. Ethonolic extract showed strong antioxidant activity and antimicrobial activity against to the bacteria, (K.pneumoniae, S. typhi, E.coli, P.aeroginosa, S.aureus) and fungus (A.nidulans, A.terreus, A.sulphureus, Candida albicans and Fusarium sp.) cultures. Due to the phytochemical diversity in the antioxidant phytocompounds, the above results were expected. It almost rich in carotenes, Neoxanthin, chlorophyll a and chlorophyll b, lutein, violexanthin, pheophytin, which may have been responsible for the antioxidant, antimicrobial and for phytochemical activity. For antimutagenic activity using sodium azide to induce the chemical compound of Sphaeranthus amaranthoides Burn, to prevent the degenerative cells and results further support the view that some Indian medicinal plants are source for potential antioxidants.Keywords

Altogether 37 species belonged to 10 genera were recorded. A preliminary screening of all the species isolated from soils were used for antifungal (antagonistic) activity against Fusarium semitectum, a known soil borne fungal pathogen. Among the species tested, Trichoderma koeningii showed promising activity, inhibited the pathogenic fungus for the maximum both in dual culture and in food poisoning technique. When HPLC fractionation of the mycelial extract of T. koeningii grown in PDA broth yielded three fractions. They were named as peak 1, peak 2 and peak 3.Among the three fractions, peak 2 alone showed the antifungal activity with the inhibition zone of 13 mm diameter against Fusarium semitectum. The functional groups present in peak 1 and 3 are almost same, but in the peak 2 some extra functional groups are present. These groups may be responsible for the antifungal activity of this fraction.

The bacterial organisms were isolated from drinking water (Bacillus, Borchothrix, Clavibacter sp, Ancylobacter sp, and Brevi bacterium). Selected Indian medicinal plants Cardiospermum halicacabum and Melothria heterophylla were selected for antibacterial studies. The solvents used for the extraction of plant ischolar_mains were n- butanol, ethyl acetate and distilled water. The invitro antibacterial activity was performed by agar well diffusion method. The most susceptible Gram-Postive bacteria was Bacillus sp, Brevibacterium sp, and the most susceptible Gram-negative bacteria was Borchothrix sp, Clavibacter sp, and Ancylobacter sp. The extracts of plant Cardiospermum halicacabum and Melothria heterophylla inhibited the growth of the bacterial strains investigated. The most active extracts was compared with the standard antibiotics, penicillin, Streptomycin and Ampicillin 100mg/disc). The results obtained in the present study suggest that Cardiospermum halicacabum and Melothria heterophylla could be used in treating diseases caused by the test organisms. The results are discussed in detail.Keywords

Investigation on the cultivation of milky mushroom, Calocybe indica was conducted to find out the growth and yield performance on different substrates. The yield of fresh mushroom obtained from paddy straw, teak leaves and sugarcane trash substrates were 1140, 745 and 570 g/kg respectively. The nutritional significance of Calocybe indica cultivated on different substrates was assessed in terms of protein, carbohydrate, amino acids and lipids. The cellulolytic activity and coir pith compost was also tested using Calocybe indica. The present result suggest, the lignocellulosic substrate like paddy straw, teak leaves and sugarcane trash shown great potential for use as a raw material since this substrate provides an economically acceptable production for Calocybe indica.Keywords
