Snack foods plays a major role in children’s growth of vital parts and size and hence this snack food industry especially flaked rice has become common in day today life. The paddy hybrids of low cost if converted into snack food fetches a huge market value both in inland and in export and the selected variables for this processing of flaked rice includes, soaking time, roasting temperature, roasting time,drying temperature and flaking time. The hybrids selected are of different characteristics and the conditions of processing for making of flaked rice differs from each other. Hence the process is optimized for each and every variety separately. The optimized product is of good characteristics in appearance and taste is also tested for the commercialisation of the optimized process. The three different levels selected were in soaking time, 24 h, 36 h and 48 h, roasting temperature, 170 °C, 180 °C and 190 °C, roasting time, 2, 4 and 6 min, gap between rollers, 2, 3 and 4 mm and flaking time, 60, 90 and 120 sec. The optimizations of all these 5 parameters were made for a maximised yield of flaked rice and the hyrbids performing on par with IR-64, the ruling check variety is found out and has to be commercialized so that the cost involved in the check variety, IR-64 can be ruled out and hybrid can be replaced. The optimum conditions of PA-6444 for maximised yield of 0.42 g/kg of paddy hybrid were, 48.0h of soaking time, 190 °C of roasting temperature, 2.0min of roasting time, 2 mm of gap between rollers and 120sec of flaking time. The central composite design was performed with 27 runs in RSM in Minitab 17.0 sofware. The analysis of variance showed that, soaking time and gap between rollers had significant change in the output yield of flaked rice. Mean yield of PA-6444 is 380.75±9.68, minimum of yield is 305.00±9.68, maximum of yield is 447.00±9.68, cv is 13.21. Mean yield of IR-64, check variety is 309.48±1.11, minimum of yield is 301.00±1.11, maximum of yield is 317.67±1.11, cv is 1.86. The correlation coefficient between predicted and actual yield for the selected PA6444 hybrid is 0.96 and that of the check variety, IR-64 is 0.94 in flaking of paddy hybrids.","PeriodicalId":213252,"journal":{"name":"Asian Journal of Microbiology, Biotechnology & Environmental Sciences","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115374056","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 productivity and quality of the produce are being measured by using advanced production technologies. Protected cultivation is an advanced agrotechnology that is utilized all over the world to generate high quality output. Indeterminate tomato is a growing crop though, still, in Punjab, no systemic work has been done for the evaluation of quality attributes of indeterminate tomato genotypes under the protected environment. Inherent diversity is a chief concern for the improvement of quality attributes in tomato. Considering the importance of tomatoes, there is an urgent need to screen out genotypes of indeterminate tomato for a best quality production and for higher nutritive value. The investigation was carried out at the Department of Vegetable Science of Agriculture, Khalsa College, Amritsar, Punjab, India and the experiment were conducted under modified naturally ventilated polyhouse following Factorial Randomized Block Design with three replications, consisting twelve genotypes including standard check during spring-summer season, 2020-2021. The data exhibited significant variation in twelve genotypes for different characters. Based on mean performance, the result let out that Punjab Gaurav and JC-165 was superior for all the quality attributes. Whereas, pericarp thickness and fruit shape index were maximum in KCA-2 while Punjab Sartaj was sophisticated for TSS, lycopene and ascorbic acid although greater titrable acidity was recorded in Arka Vikas. Significantly, the result was higher due to the favorable conditions provided in a protected environment during the growing period with the interaction of genes of genotype.","PeriodicalId":213252,"journal":{"name":"Asian Journal of Microbiology, Biotechnology & Environmental Sciences","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115663655","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}

Ecological and socioeconomic impacts of some invasions are enormous, which have provided much impetus for the study into this area. When all species compete to survive, invasive alien plant species (IAPS) tend to have specific traits or their combinations which allow them to outcompete the native species. In certain cases, the competition is about rates of growth and reproduction. In other cases, they may interact with each other more directly. This study on Mimosa diplotricha, IAPS in the Palakkad Gap of the Western Ghats in South India is intended to trace its dominance and invasion in the region and also to conserve the Palakkad Gap, which is a biodiversity hotspot.","PeriodicalId":213252,"journal":{"name":"Asian Journal of Microbiology, Biotechnology & Environmental Sciences","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116530128","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 experimental design used was composed of randomized blocks, in a 2 x 5 + 1 factorial scheme, with two moisture levels (50 and 75% field capacity) and five doses of nitrogen (0, 25, 50, 100 and 200 kg ha-1, with the addition of water-retaining gel, besides an additional treatment, without gel addition, with moisture at a level of 100% field capacity and standard nitrogen fertilization (100 kg ha-1), which will consist of the control treatment, with five replications. The analyzed variables were: water content, germination, germination speed index, electrical conductivity, and accelerated aging. The evaluated factors showed no significant interaction, for most of the analyzed variables, with the exception of the germination speed index. For germination, there was significant effect for the ‘levels of moisture in the substrate’ factor. Comparing the means of the treatments with the control, for electrical conductivity, all treatments had lower EC values, which indicate better vigor. It is concluded that using water-retaining gel associated with nitrogen fertilization allows the use of lower levels of moisture in the substrate (50%), without affecting the quality of the produced seeds.

The search for new compounds effective against human diseases is still a priority in medicine. The evaluation of microorganisms isolated from non-conventional locations offers an alternative to look for new compounds with pharmacological activity. Endophytes are a natural source with remarkable chemical and biological properties. Endophytes are considered promising sources of new bioactive natural products.
