Antimicrobial-resistant microorganisms have become a major challenge for public health and food industries because of their fast adaptability and slow response to synthetic antimicrobials. Bioactive compounds from marine sources exert various biological roles including antioxidant, antimicrobial, anti-inflammatory, antihypertensive, and anticancer properties. Their advantage as an antimicrobial compound is gradually be exploited, particularly in marine-based foods (MBFs), which are highly perishable since they are abundant in proteins, lipids, and other nutrients. Also, the growing demand for fresh products with prolonged shelf-life is making the MBFs industry to urgently seek the effective methods for preservation of fresh or refrigerated MBFs. Crustaceans, which are invertebrates, are valuable source of essential nutrient based on their richness in protein, carbohydrate, minerals, lipids, and vitamins. Additionally, the by-product from the processing of crustaceans could be used as an alternative source of antimicrobials, which can be employed in MBFs as natural preservatives. This review therefore revisited the recovery of antimicrobials compounds such as antimicrobial peptides, carotenoids, and chitosan derivatives from crustaceans. The uses of these crustacean antimicrobials in extending the shelf-life of MBFs are also discussed.

Helichrysum graveolens (Bieb) Sweet possesses various medicinal applications such as diuretic, treatment of the sand and stone in kidney, regulation of digestion problems and strenghtening of the immune system. The investigation was carried out to reveal ethanol extracts of flower and stem parts of H. graveolens for antimicrobial, antioxidant, anti-tyrosinase and anti-urease activities. Ethanol extract of stem part of H. graveolens exhibited more antibacterial activity against growth of bacteria except for K. pneumoniae. Stem part of H. graveolens has higher copper reducing antioxidant capacity (CUPRAC) and anti-urease activities than flower part of H. graveolens. Anti-tyrosinase activity (IC50 values) of stem and flower parts of H. graveolens was found to be 0.01549 ± 0.0006 μg/ml and 0.01515 ± 0.0016 μg/ml, respectively. This survey suggests that ethanol extracts of different parts of H. graveolens is an alternative source for natural antioxidant and antimicrobial compounds, urease and tyrosinase inhibitors that could be utilized in drug and food industries.

Natural gas is a source of energy that comes from the earth which is depleting every day, an alternative source of energy is needed and one of the sources comes from biogas. There is an abundance of empty fruit bunch (EFB) that comes from palm oil plantation that can become a substrate for biogas production. A methodology of fermentation based on Verein Deutscher Ingenieure was used to utilize EFB as a substrate to produce biogas using biogas sludge and wastewater sludge as inoculum in wet fermentation process under mesophilic condition. Another optimization was done by adding a different water ratio to the inoculum mixture. In 20 days, an average of 6gr from 150gr of total EFB used in each sample was consumed by the microbes. The best result from 20 days of experiment with both biogas sludge and wastewater sludge as inoculum were the one added with 150gr of water that produced 2910ml and 2185ml of gas respectively. The highest CH 4 produced achieved from biogas sludge and wastewater sludge with an addition of 150gr of water to the inoculum were 27% and 22% CH 4 respectively. This shows that biogas sludge is better in term of volume of gas that is produced and CH percentage.

The Rural development generally refers to the process of improving the quality of life and economic welfare of people living in relatively isolated and sparsely populated areas. Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) is considered as a “Silver Bullet” for eradicating rural poverty and unemployment, by way of generating demand for productive labour force in villages. It provides an alternative source of livelihood which will have an impact on reducing migration, restricting child labour, alleviating poverty, and making villages self-sustaining through productive assets creation such as road construction, cleaning up of water tanks, soil and water conservation work, etc. For which it has been considered as the largest anti-poverty programme in India. In this paper, based on the secondary data, an attempt has been made to comprehensively understand the development effort to rebuild the rural life and livelihood on the basis of various secondary data.

Fungi is known to produce a wide range of biologically active metabolites and enzymes. Enzymes produced by fungi are utilized in food and pharmaceutical industries because of their rich enzymatic profile. Filamentous fungi are particularly interesting due to their high production of extracellular enzymes which has a large industrial potential. The aim of this study is to isolate potential soil fungi species that are able to produce functional enzymes for industries. Five Aspergillus species were successfully isolated from antibiotic overexposed soil (GPS coordinate of N3.093219 E101.40269) by standard microbiological method. The isolated fungi were identified via morphological observations and molecular tools; polymerase chain reactions, ITS 1 (5’- TCC GTA GGT GAA CCT GCG G3’) forward primer and ITS 4 (5’-TCC TCC GCT TAT TGA TAT GC-3’) reverse primer. The isolated fungi were identified as Aspergillus sydowii strain SCAU066, Aspergillus tamarii isolate TN-7, Aspergillus candidus strain KUFA 0062, Aspergillus versicolor isolate BAB-6580, and Aspergillus protuberus strain KAS 6024. Supernatant obtained via submerged fermentation of the isolated fungi in potato dextrose broth (PDB) and extracted via centrifugation was loaded onto specific media to screen for the production of xylanolytic, cellulolytic and amylolytic enzymes. The present findings indicate that Aspergillus sydowii strain SCAU066 and Aspergillus versicolor isolate BAB-6580 have great potential as an alternative source of xylanolytic, cellulolytic and amylolytic enzymes.

Source Materials

This study was an attempt to understand how the available alternative source materials, such as oral testimonies can serve as valuable assets to unveiling certain aspects of maritime history in India. A number of themes in maritime history in India failed to get the attention of the generation of historians, because of the paucity of written documents. Unlike in Europe, the penning down of shipping activities was not a concern for the authorities at the port in India. The pamphlets and newsletters declared the scheduled departure of the ship in Europe but, in India, this was done verbally. Therefore, maritime history in India remained marginalised. Hence, in this article, I make an endeavour to perceive how the oral testimonies can help shed some new light on certain aspects of maritime history in India, such as life on the ship, maritime practices, and perceptions among the littoral people in coastal societies. This article also outlines an approach on how the broader question on the transformation of scattered maritime practices among coastal societies can be adapted and transferred into an organised institution of law by the nineteenth century, and how these can be pursued in future. I also suggest in this article that the role of Europeans, especially the British, in the process of transformation, can be investigated further through oral testimonies in corroboration with the colonial archival records.
