Comparative biomass evolution of microalgae scenedesmus sp. between a raceway and a tubular photobioreactor for CO2 capture

Paper ID- AMA-22-06-2022-11485

A comparison of culture biomass evolution for the microalgae Scenedesmus spinosus in a tubular pilot photobioreactor of 1.6 m³ and a raceway pilot photobioreactor of 1.2 m³ was carried out, using a nutritional Z-8 medium with the injection of carbon dioxide, and using an electronic system for monitoring and control of operational variables. For three weeks of testing, each culture was exposed to three pH levels of 6.5, 7.0 or 7.5, where random samples from both bioreactors were taken three times a week, to analyze pH, turbidity, transmittance at 640 nm and temperature. At the beginning and the end of culture, total solids were analyzed, and photographs were taken with a microscope to study the cell conditions of culture. This study revealed that the highest biomass production of Scenedesmus spinosus was obtained at pH 6.5 in the raceway photobioreactor, with a productivity of 371 g m-3 day-1, 0.78 % total solids, a turbidity of 858 NTU and 5% transmittance at the end of the culture.

A new report of Cystolepiota moelleri from South east Asia on the basis of Morphoanatomical and DNA Barcoding

Paper ID- AMA-22-06-2022-11483

Cystolepiota is rarely studied in Pakistan, here we survey and describe new record of Cystolepiota from Himalayan moist temperate region of Pakistan. Originally, it was described from Europe. Cystolepiota moelleri Knudsen resembles with Western Asian collection in having free lamellae and non-dextrinoid spores. It differs in its rounded pileus and cylindrical cheilocystidia. The species is provided with full morpho-anatomical and phylogenetic description with line drawings of the microcharacters, discussion of related and similar species, and molecular data.

Comparative effects of inorganic and organic trace minerals supplementation on the expression of immune regulatory genes in broilers

Paper ID- AMA-21-06-2022-11480

Broiler production in tropical countries is generally sub-optimal. Inorganic and organic trace minerals supplementation improves immunity, growth performance in the broilers. In the poultry diet, trace minerals (zinc [Zn], selenium [Se], and chromium [Cr]) are normally administered in the inorganic form which has been traditionally considered as the most cost-effective and easily available but organic forms of these trace minerals have a higher bioavailability, lower dietary inclusion and cause less environmental pollution as compared to inorganic form. This study aimed to investigate the effect of different concentrations of organic and inorganic forms of trace minerals (Zn, Se and Cr) supplementation (0-35 days) in immune regulatory genes expression and biochemical parameters in broilers. A total of 216 broilers were randomly divided into twelve groups supplemented with different concentration of these trace minerals. RT-PCR expression analysis of ChIL-12p35 and ChIFN- genes in the bursa of Fabricius and spleen revealed that maximum up-regulation of ChIL-12p35 was in the T3 group; whereas, the maximum up-regulation of ChIFN- gene was in the T12 group as compared to the control group. Total serum protein, albumin, globulin and serum electrolyte were significantly higher (p<0.05) in the organic trace mineral supplemented group. From the present study results, it can be concluded that the effect of supplementing organic trace minerals to broilers on the expression of the immunoregulatory gene and biochemical parameters is better than their inorganic counterpart.

Qualitative Phytochemical Screening and Exploration of some in vitro Biological activities of Phytolacca latbenia (MOQ.) H. WALTER from Pakistan

Paper ID- AMA-21-06-2022-11477

The current study was to evaluate secondary metabolites, curative antimicrobial and antioxidant agents of an ethnobotanically important plant i.e., Phytolacca latbenia (Moq.) H. Walter. Phytochemical screening explored the presence of different secondary metabolites. Ethanol extracts of leaves were most potent against all the testing bacterial strains. Antibacterial activity was determined using agar well diffusion method. The zones formed by ethanol extracts of leaves were, 23.16±0.11mm, 18.05±0.04mm, 25.15±0.11mm and 12.75±0.06mm against Staphylococcus aureus, S. epidermis, Acinetobacter baumannii and Pseudomonas aeruginosa, respectively. The chloroform and ethanol extracts showed bigger zone of inhibition as compared to the standard antibiotic against S. aureus and P. aeruginosa. Likewise ethanol extract of leaves has more inhibition potential against S. epidermidis and A. baumannii. This potential was accompanied by using standard five reported assays. Percentage inhibition of DPPH• of fruits (81.08±0.133%) was greater than leaves (69.86±0.183%). Even the sample plant extracts showed the greater potential of inhibition than synthetic antibiotics. Percentage inhibition of ABTS•+ of leaves (59.26±0.140%) was greater than fruits (58.45±0.246%). The values of FRAP assay and TFC of leaves (0.53±0.014 mM Fe2+ equivalent/g and 27±0.02 mg CE/g) were greater than fruits (0.212±0.028 mM Fe2+ equivalent/g and 14.15±0.024 mg CE/g) whereas TPC of fruit (404±0.005 mg GAE /g) were greater than leaves (72.91±0.059 mg GAE /g).

A study of economics of leguminous crops (seasumum and chickpea) in the rainfed areas of the Jammu region

Paper ID- AMA-20-06-2022-11474

As India ranks first in the possession of the rainfed area, the utilisation of the same effectively will help in ensuring high remunerative income for the farmers. In this context, the cultivation of the legume crops in these areas will not only facilitate the nutrition requirements of the otherwise poor-fed farmers of these regions, on the one hand, but will also help in making the agriculture more sustainable, on the other. The present stud was conducted in the rainfed regions of Jammu and Udhampur regions. Apart from the usual tool of CACP, functional analysis (Cobb-Douglas production function) was employed for the resource-use efficiency. This was further been assisted by the concept of marginal value productivity (MVP). The total cost of production (C2) was found out to be Rs. 9029.72 per acre (in case of sesamum in Jammu district) and Rs. 8933.25 per acre (in case of chickpea in Udhampur district). Net returns were found out to be higher in case of chickpea (Rs. 8456.25 per acre). Consequently, the cost-benefit ratio was found to be higher in case of the former (1:1.95). Further, the value of the coefficients (significant) were found out to be 0.691 (human labour), 0.042 (Machine labour) and 0.291 (fertilisers) in case of sesamum crop and 0.122 (fertilisers) in case of chickpea. There is thus need to enhance the area under these crops in the rainfed area of the Jammu and Udhampur district and moreover, human labour should be given due importance that can influence the yield and productivity of the crops in the rainfed areas.
