International Journal of Biotechnology (IJBT)

Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Genetic diversity of commonly available ornamental fishes in Bangladesh   Order a copy of this article
    by Md. Alamgir Kabir, Md. Golam Rabbane 
    Abstract: Ten primers OPA-05, OPE-05, OPE-04, OPC-04, OPB-04, OPG-01, OPB-01, OPB-02, OPD-04, and OPE-03 were used to identify genetic diversity in five ornamental fish species: common goldfish (Carassius gibelio), tiger barb (Barbus tetrazona), comet goldfish (Carassius auratus), angel fish (Pterophyllum scalare), and sucker fish (Hypostomus plecostomus). Eighty seven polymorphic bands were observed, showing 100% polymorphism, likely due to the species different taxonomic positions. Common goldfish and comet goldfish exhibited the highest genetic similarity (0.7167), while common goldfish and tiger barb showed the lowest (0.4667). Cluster analysis placed tiger barb in a separate group due to greater genetic distance. Common goldfish and comet goldfish formed one cluster, angel fish and sucker fish another and both clusters were combined into a broader group, reflecting their genetic relationships. Overall, the findings highlight genetic differences consistent with their taxonomic classifications which can be used for taxonomic and conservation studies of these fish species.
    Keywords: genetic diversity; ornamental fishes; RAPD analysis; taxonomic position; conservation.

  • Analysing PMJDY program influencing rural households decision-making method   Order a copy of this article
    by Y. Jenusha Ananthy, K. Asha 
    Abstract: This research underwent an empirical investigation to examine the benefits of the PMJDY program in customer awareness and perception among rural households of Tamil Nadu, India. The research was primarily focused on the following topics: 1) customer awareness and perception; 2) money transactions; 3) behaviour of the banking sector; 4) standard of living; 5) bank infrastructure; 6) economic connect. This is a clear-cut policy that can be examined through this research effort since it plays a significant role. The proposed approach was implemented in two stages. The first step began with the collection of data, which had explicitly examined the PMJDY program benefits. The data was collected using a structured questionnaire that comprises 20 questions. The evaluation was carried out for the collected data using SEM.
    Keywords: Pradhan Mantri Jan Dhan Yojana program; PMJDY program; customer awareness level; perception; financial services; rural area.

  • Harnessing agricultural wastes for in-vitro alcohol production: a waste-to-wealth approach   Order a copy of this article
    by R. Chandrika, T. Sushma, G.V. Komala, Umme Haani, S. Lokesh, M.C. Madhusudhan 
    Abstract: Agricultural waste is an abundant and cost-effective resource for bioethanol production. This study explores the production of reducing sugars and ethanol from three lignocellulosic substrates such as areca nut husk, banana pseudo stem, and corn cob at varying concentrations (10 g, 15 g, and 25 g) using different pre-treatment methods. Acid hydrolysis, enzyme treatment, and precursor addition (1% sucrose) were applied to enhance sugar and ethanol yields. Results revealed that precursor-treated samples after acid hydrolysis produced the highest sugar and ethanol yields, with BPS at 25 g showing the maximum reducing sugar (5.88 +- 0.06 mg/g) and ethanol production (13.00 +- 0.30 ml/L). Areca nut husk and corn cob demonstrated lower yields, with corn cob being the least effective. Ethanol production increased with substrate concentration and fermentation time. The findings emphasise the importance of combining effective pre-treatment methods to maximise bioethanol production.
    Keywords: acid hydrolysis; agricultural waste; biofuels; lignocellulosic conversion; bioethanol production.
