Fermentation is carried out mostly by LAB which are much resistant to salt. Pickles usually contain a variety of LAB which not only improve digestion of fruits and vegetables but also contribute to unique taste by providing components like exopolysaccharides and bacteriocins. The production of bacteriocins by LAB is useful for human body and are beneficial to reduce growth of foodborne pathogens like S. aureus and E. coli etc. LAB have been used in fermented food industry because they improve the taste of product. From different samples of pickles eighteen Lactic Acid Bacteria (LAB) have been isolated in the current work. The isolates were screened on De Mann Rogosa Sharpe agar (MRS). After preliminary morphological and biochemical examination, twelve out of eighteen strains were identified as Lactobacillus species, while four were Streptococcus species. Antibacterial activity of eight bacteriocin-producing Lactic acid bacterial (LAB) strains were tested against three pathogenic bacteria Escherichia coli (E.coli), Bacillus cereus (B.cerus) and Staphylococcus aureus (S.aureus) by using disk diffusion method. Maximum antibacterial activity was observed against B. cereus and least against E. coli. Bradford method was used in order to estimate the protein bacteriocin. The protein content was measured by comparing it with the bovine serum albumin (BSA) as a standard. LAB are beneficial bacteria for human health as these can be used as natural antibacterial tools against common pathogenic bacterial strains involved in different types of deleterious infections","PeriodicalId":485309,"journal":{"name":"Pakistan journal of biotechnology","volume":"21 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141920494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These challenges include issues with soil fertility, pest and disease pressure and shortages of high-quality seed potatoes. The scarcity of high-quality seeds is a massive hassle in Pakistan. Farmers in Pakistan, often reuse their seeds or obtain them from informal sources. This practice leads to increased seed quality deterioration and tuber-borne diseases, resulting in decreased yields. To address this situation, aeroponic techniques can effectively meet this challenge. Aeroponics is a novel technique for producing high-quality seed potato, aiming to address the challenge of seed production. Aeroponic techniques are commercially practised in many countries. Thus, in this review, we have highlighted the importance of aeroponic technology and how this technique can help uplift/boost up the seed potato production system in Pakistan. The overview concludes that aeroponic seed production offers numerous benefits, including improved yields, and resistance, even as keeping natural resources. Despite the challenges, the evaluation indicates that the implementation of aeroponic seed production technology in Pakistan may offers a promising and sustainable technique for seed potato production in Pakistan.","PeriodicalId":485309,"journal":{"name":"Pakistan journal of biotechnology","volume":"179 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140446040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drilling method was highly effective to improve seed yield apart from the lower biological yield due to greater harvest index as compared to rest of the sowing methods. Although, recommended plant spacing (55,555 plants ha-1) produced better individual plant based results, but due to lesser plant population, the overall seed yield was greater under high density planting (66,666 plants ha-1).Ultra high density plantation (83,333 plants ha-1) did not prove beneficial due to crowded plant population where harvest index became poor but biological yield increased.

Thus, it is necessary to ensure the availability of nitrogen according to the requirement of the crop through the foliar application of urea; because it is proven more efficient when compared with soil-applied method, especially in wheat crop. Therefore, the study was designed to examine the effect of urea in foliar application under different concentrations on various growth stages of wheat under field conditions during 2020-2021. The wheat variety Benazir-2013 was selected because it is high-yielding, rust-resistant, and can be cultivated in all ecological zones of Sindh. Due to these prominent characteristics, nowadays, it is a better choice for growers. For the foliar application of urea, the concentrations were formulated as T1: Control, T2: Recommended dose of fertilizer RDF + 1% Urea on tillering stage, T3: RDF + 1% Urea at stem elongation, T4: RDF +1.5% Urea at tillering stage, T5: RDF + 1.5% Urea at stem elongation, T6: RDF + 2% Urea at tillering stage and T7: RDF + 2% Urea at stem elongation. Results of the study showed that maximum Plant height (94.7 cm), number of tillers (460.3 m-2), Spike length (16.7 cm), number of grains spike-1 (65.8), Seed index (65.8 g), Biological yield (11.6 t ha-1) and Grain yield (5.0 t ha-1) was perceived by (T6: RDF + 2% Urea at tillering stage) followed by (T7: RDF + 2% Urea at stem elongation) with Plant height (90.4 cm), number of tillers (430.0 m-2), Spike length (14.8 cm), Grains spike-1 (58.3), Seed index (53.5 g), Biological yield (11.1 t ha-1) and Grain yield (4.8 kg ha-1). Meanwhile, the lowest values were recorded for all yield traits under T1: Control. However, T2, T3, T4, and T5 were also recorded significantly compared to the (T1) control. Hence, it is suggested that RDF + 2% urea at the tillering stage should be applied in wheat variety Benazir-2013 to achieve the maximum yield.","PeriodicalId":485309,"journal":{"name":"Pakistan journal of biotechnology","volume":"101 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140449898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The average values of phenotypic traits like neck length of desi and fayoumi males measured in cm (20.4±1.9), (16.5±1.4) body height (43.4±3.2), (33.7±3.2) shank length (12.5±0.82) (8.3±0.72) beak length (3.6±0.21) (2.7±0.16) and wings span (23.7±1.6) (18.3±1.5) in intensive conditions. While as, in the free range conditions the neck length of desi and fayoumi males was recorded in cm (18.7±1.6) (16.4±1.3) body height (38.7±3.2) (34.6±3.1), shank length (10.3±0.97) (9.4±0.94), length of beak (3.3±0.24) (2.7±0.18), and wing span (20.4±1.5) (18.5±1.4), in both chicken breeds. The different phenotype traits of desi and fayoumi chicken breeds viz., the color of eyes, comb, plumage, feather, barbell, mumps, and beak colors percentage were found with variation in intensive and free range conditions. Concludingly, desi chickens were found with larger body parts with dark color variants. The present study suggests, more work should be carried on other characteristics to enhance poultry quality and quantity in future endeavors.","PeriodicalId":485309,"journal":{"name":"Pakistan journal of biotechnology","volume":"29 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140450552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
