Publication Advanced Development of Bio-fertilizer Formulations Using Microorganisms as Inoculant for Sustainable Agriculture and Environment – A Review(USIM Press, 2022) ;Nur Maisarah Mohamad SarbaniNazariyah YahayaConventional types of fertilizer such as chemical and synthetic fertilizers have demonstrated various adverse effects on the environment, crops, and humans. The utilization of plant probiotics as a bio-fertilizer in agriculture has been recognized to benefit the growth of the plant and inhibit the activity of plant pathogens. Traditional formulations of bio-fertilizer have provided insight into the beneficial use of microorganisms in crops. Despite its advantage to the environment, the effectiveness of traditional bio-fertilizer is common as compared to chemical fertilizer. Thus, a variety of bio-fertilizer formulations have been developed to improve the success rate of bio-fertilizer in increasing plant productivity. This review was focused on the development of bio-fertilizer formulation and the potential of bio-fertilizer to substitute chemical fertilizer application. In addition, this research review was also undertaken with a great demand on producing low cost and highly effective fertilizer without harming the environment and humans. Thus, the advantages and disadvantages of each formulation type have also been reviewed, emphasizing the perspective of bio-fertilizer and their suitability as bio-fertilizer as a substitute for chemical fertilizers in sustainable agriculture. - Some of the metrics are blocked by yourconsent settings
Publication Duckweed as a future food: Evidence from metabolite profile, nutritional and microbial analyses(Elsevier, 2022) ;Nazariyah Yahaya ;Nabila Huda Hamdan ;Atiqah Ruqayyah Zabidi ;Ammar Mirza Mohamad ;Mohammad Luqman Hakim Suhaimi ;Muhammad Azhan Azfar Md Johari ;Hanis Nadia YahyaHafiza YahyaDuckweed species are nutritionally meaningless plant which grow wildly in unattended areas. Therefore, understanding the metabolites content in duckweed species is essential for designing a future food products. Here, we report an untargeted Gas Chromatography-Mass Spectrometry (GC-MS)-based metabolomics approach for comprehensively discriminating between Lemna minor and Wolffia globosa of duckweeds species using principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA). Ten differential metabolites levels were tentatively identified between L. minor and W. globosa. Relative to W. globosa, L. minor appeared to enrich with 5-Hydroxyl-L-tryptophan, Tocopheryl acetate, Naringenin, α-linolenic acid and glutamic acid. Furthermore, the nutritional and microbial analyses of ice cream formulated with dried L. minor were investigated. The nutritional analysis results show that relative to control, the ice cream with 2% dried L. minor had significantly increased protein, fiber and ash content. In addition, total plate count (TPC) for microbial analysis of duckweed ice cream was performed. The result suggested that the small amount of bacteria (3.82 cfu/g) was traced in formulated ice cream with 2% dried L. minor. Overall, the metabolites profile, nutritional and microbial analyses of food used L. minor plant indicate that duckweed is a good candidate for future food. - Some of the metrics are blocked by yourconsent settings
Publication Influence Of Neck Slaughtering In Broiler Chicken Meat On Physicochemical Analysis And Metabolites 'fingerprinting' To Enhance Meat Quality(Elsevier, 2021) ;Shikh Mohd Shahrul Nizan Shikh Zahari ;Nurfatin SyahirahMohamed Ali ;Atiqah Ruqayyah Zabidi ;Dzulfadli Rosli ;Mohd Nazmi Abdul ManapNazariyah YahayaAnimal slaughtering is the most vital step in the preparation of chicken meat. The step ensures the meat is safe for human consumption since the procedure of animal slaughtering can affect the meat quality. In this study, we compare the quality of chicken meats obtained via two common slaughtering procedures: neck slaughtering (NS) and neck pocking (NP). The meat quality was assessed based on physicochemical analyses (ultimate pH, colour, heme iron content, drip and thaw loss measurements and TBARS value) and metabolite profiling (FTIR, GC–MS and UHPLC with PCA and PLS-DA). The study found that, relative to the NP-, the NS-chicken meat had slightly acidic pH, and much lower values of the following parameters: L* (lightness) (P = 0.023), heme iron content (P < 0) and TBARS (P < 0.01). Comparing FTIR spectra, the metabolite fingerprints of both meats looked slightly different. This was confirmed to be due to a set of differential metabolites present in the NS and the NP-chicken meats, as recorded by GC–MS and UHPLC-TOF-MS data after analyzing with PCA and PLS-DA. Compared to the NP, the NS-chicken meat was rich in metabolites with health benefits, including n-3-polyunstaurated fatty acids (PUFA), triglyceride (TG), cytadine and uridine. In addition, the NS-chicken meat also contained much lower concentrations of free amino acids. This is desirable as free amino acid-deficiency is able to suppress the production of biogenic compounds, a group of chemicals that produce toxicological effects on human heath when taken excessively. - Some of the metrics are blocked by yourconsent settings
Publication Pectin from Duckweed (Lemnaceae) As Potential Commercial Pectin and Its Gelling Function in Food Production: A Review(USIM Press, 2022) ;Hanis Nadia Yahya ;Nazariyah Yahaya ;Kamilah Huda Baihagi ;Norlelawati AriffinHafiza YahyaDuckweed, a small flowering plant which comes from Lemnaceae family, has been rising in popularity to many researches and applications for its numerous valuable functional properties. One of its special features is fast growing plant and easily adapted to various types of regions which makes it attractive to be manipulated in many applications including in biofuel production, waste water treatment and also for pharmaceutical and medicinal purposes. Pectin is the common component found in plant cell wall and it has been used as food additive for its capability to gel, emulsify and stabilize food products. Several requirements for commercial pectin such as galacturonic acid content (GalA) and degree of amidation have been regulated. Studies have proven that duckweed have significant amount of pectin which make it as a potential source of gelling agent in food industry. However, the structural properties of pectin from duckweed need to be investigated, in order to ensure if they meet the regulated requirements for industrial production. It is also to determine the suitability of duckweed pectin utilization in different type of food products since pectin of different sources have different structural characteristics, thus exhibit different gelling capability. This present review discusses on the potential of pectin from duckweed species to be utilized as food additive with gelling function in food products. Several extraction methods also have been reviewed, which each of them showed different efficiency and affect the extracted pectin characteristics. - Some of the metrics are blocked by yourconsent settings

Publication Recombinase Polymerase Amplification and Their Application in Phytopathogen Detection(USIM Press, 2022) ;Wan Hawa Najibah Wan Rasni ;Nazariyah YahayaMaryam Mohamed RehanDNA identification method is indispensable for the detection of a plant pathogen. However, established techniques, though reliable, requires advanced equipment, and their application outside specialized laboratories is limited. Along with the advancement of molecular techniques, several isothermal amplification methods, including Recombinase Polymerase Amplification (RPA), has been developed in this study. In fact, RPA is a rapid and sensitive amplification method, operating optimally at 37-42 degree celcius for 15 to 30 minutes with minimal sample preparation, and can amplify as low as 1-10 target copies. Furthermore, RPA has been a favourable method for the detection of plant pathogens due to its advantageous parameters. This review presents the current knowledge of RPA and its application in plant pathogen detection.
