Rhodotorula Rubra

Seaweed processing generates liquid fraction residual that could be used as a low-cost nutrient source for microbial production of metabolites. The Rhodotorula strain is able to produce antimicrobial compounds known as sophorolipids. Our aim was to evaluate sophorolipid production, with antibacterial activity, by marine Rhodotorula rubra using liquid fraction residual (LFR) from the brown seaweed Macrocystis pyrifera as the nutrient source. LFR having a composition of 32% w/w carbohydrate, 1% w/w lipids, 15% w/w protein and 52% w/w ash. The best culture condition for sophorolipid production was LFR 40% v/v, without yeast extract, artificial seawater 80% v/v at 15 °C by 3 growth days, with the antibacterial activity of 24.4 ± 3.1 % on Escherichia coli and 21.1 ± 3.8 % on Staphylococcus aureus. It was possible to identify mono-acetylated acidic and methyl ester acidic sophorolipid. These compounds possess potential as pathogen controllers for application in the food industry.

As we all know that India is known for its agricultural products rather than its industrial goods. Farmers produce crops and they pet several animals. The waste produced from their animals and crops are utilized by them to some extent but due to unawareness a lot of material goes on waste. Some of these wastes are Bagasse fiber and chicken feather. Also these alternate materials are environment Friendly as well as biodegradable. In poultry industry chicken feather is waste material but it posses high toughness and insulation and is also used as good reinforcing material in polymer matrix composite due to low density, low cost and high aspect. Bagasse having high tensile strength contains about 40% cellulose, 30% hemicelluloses, and 15% lignin which are modified by creating quionones in lignin portion of the fiber and reacting with the furfural alcohol to increase their adhesiveness. Short Natural fibers like chicken and long fibers like bagasse were used in hybrid combination and the fiber weight fraction of 5%, 55% and 40% were used for the fabrication of the composite in epoxy Resin. This composite is manufactured using hand layup process. Mechanical properties of composite are determined through hardness and impact tests. Water absorption tests were conducted by immersing specimen in a water bath at room temperature for different time durations.

Immobilized Microorganism

In order to establish a low cost and high efficiency immobilized microorganism system to treat Cr (VI) wastewater, the effects to removal capacity to Cr (VI) of microbe strain, additives and medium were investigated. These strains were immobilized with SA (sodium alginate) by immobilized microorganism technology combined with three additives CNTs (carbon nanotubes), activated carbon, straw and nutrient source, respectively. The results showed that three kinds of additives could improve the removal effect to Cr (VI), and the removal rate up to 30% when Cr (VI) concentration was 10mg/L. There was not a significant difference among these additives. The solution contains 40% medium could significantly improve the removal capacity to Cr (VI). The removal rate could reach more than 98% when Cr (VI) concentrations were 10mg/L-20mg/L. Therefore, efficient strains, additives and medium could improve the removal capacity to Cr (VI) of immobilized microorganism technology. It can be widely used in chromium contaminated wastewater.

Xanthan gum is one of the polysaccharides most commonly used in a broad range of industries (food, cosmetics, pharmaceutical, etc.). Agro-industrial by-products are being explored as alternative low-cost nutrients to produce xanthan gum by Xanthomonas campestris. In this study, for the production of xanthan gum, sugar beet molasses and chicken feather peptone (CFP) were used as carbon and nitrogen sources, respectively. X. campestris produced the highest level of xanthan gum (20.5 g/L) at 60 h of cultivation using sugar beet molasses (40 g/L total sugar) supplemented with CFP (4 g/L) at pH 7, 200 rpm, and 30 °C. The pyruvic acid content of the xanthan gums increased with increasing CFP concentration. Compared with commercial organic nitrogen sources (tryptone, bacto peptone, and yeast extract), the highest production of xanthan gum was obtained with CFP. Moreover, among the tested peptones, the highest pyruvic acid (3.2%, w/w) content was obtained from CFP. The usage of sugar beet molasses and CFP as substrates in industries would enable a cost-efficient commercial production. These results suggest that sugar beet molasses and CFP can be used as available low-cost substrates for xanthan gum production by X. campestris.

Chicken Feather Fiber

Concrete reinforcement with fibers is undergoing findings in order to manufacture concrete with low cost but improve mechanical and microstructural properties. Chicken feather fiber(CFF) possesses characteristics, which can improve the mechanical and microstructural properties of the concrete. Concrete is a brittle material with no tension. In this study, samples A (control sample), B1 and C1 constitute of 0%, 1% and 3% by weight of CFF while B and C constitute of 0.5% and 1.5% equal proportion of CFF and Synthetic hair fiber(SHF) respectively. Concrete with CFF and CFF/SHF composites were tested to determine water absorption (WA), thickness swelling (TS), compressive strength (CS) and splitting tensile strength (STS) between 7 to 28 days of curing. Results of WA of concrete increased after 28 days to 10.01%, 12.52% and 23.11% for samples A, B1, C1 and 11.83% and 17.67% for samples B and C respectively. Similarly, TS increased after 28 days to 0.13%, 0.22% and 0.32% for samples A, B1and C1 and for samples B and C it remains stable at 0.25%., respectively. CS of samples A and B1 increased with curing days to values of 20.66 MPa and 9.36 MPa, respectively. However, for samples C1, B and C it decreased to 3.74 MPa, 9.98 MPa and 4.29 MPa. STS of A, B1 and C1 increased with curing days with values of 13.94 MPa, 8.91 MPa and 2.26 MPa respectively while samples B and C decreased with curing days with values of 5.43 MPa and 2.39 MPa respectively, after 7 days. Results of SEM deduced that CFF improves the ductility of ICBs but increased in the proportion resulted in reduction of the STS of the concrete. Similarly, SHF offers higher CS but also serves the purpose of reduction in micro cracking and increasing structural stability.
