Abstract: Background: Cellulose is mainly dominating Agricultural waste and available naturally on earth as  biopolymer. Being a  renewable and abundant resource, it can be degraded by cellulase producing microbes.  Generally, the raw material is considered as key factor in enzymatic production. Solid waste materials that are often reliable and abundant can be the best substitutes per se. Cellulase enzyme has been reported in numerous biotechnological applications including chemicals, single cell protein, food  and agriculture. Thus, increasing potential of cellulase applications prompts screening for isolation of newer cellulase producing microorganisms, which can meet the industrial demand. Keeping in view the potential applications of cellulases, the present min-review was undertaken to summarize the role of microbes in sustainable cellulase productions using diverse solid waste feedstock to make the process economically viable. Methods: Microbial information regarding underutilized plants was acquired from a literature exploration of diverse databases for instance Scopus, Google Scholar and Pubmed. Results: Earlier studies revealed that traditionally only wheat and rice based sources were used. However, with the advent of time many other solid wastes like  Coconut coir pith, Sweet sorghum silage, Sugar Cane, Round nut shell, Palm Kernel Cake, Rice bran,  Filter Paper Cornmeal, Soybean hull, Soybean hull, Corn cob residue and wheat, bran ,Corn silage digestate, Soybean hulls and wheat bran, Soybean hulls and wheat bran, Paper, wood, litmus paper Freshly ripe tomato fruit, Olive processing residue, Apple pomace, Sawdust, Bagasse. Conclusion: The biotechnological facet of cellulase research using solid waste feedstock and their future prospects are also elaborated.

Abstract: Inks are colored fluid suspensions formulated to reproduce colorful images on sorbent surfaces. The materials used in ink making may present their undesirable unique environmental hazards and challenges. Pigments and dyes used for commercial ink brands are expensive and sometimes contain toxic substances which if inadvertently ingested by humans, especially children, may be harmful to health. Also, conventional inks are less environmentally friendly hence the need for organic and eco-friendly substitutes. This study investigates the suitability of different plant-based formulations produced from Azardirachta indica and Carica papaya as substitutes for dry erase ink. The formulations were evaluated for colour, density, pH, drying time, colour stability and viscosity. Inks formed from A. indica were more stable than C. papayaA. indica inks recorded higher density (1.05-0.84 g/cm3) than inks made from C. papaya (1.02-0.87 g/cm3). Drying time ranged between 8 – 14 seconds in C. papaya and 6 – 12 seconds for A. indica. pH values were higher in C. papaya (6.8-7.5) but lower in A. indica (5.2-5.6). The viscosity was higher in C. papaya (8.55 -13.37kg/m-1s-1) but lower in A. indica (7.66 -12.87-kg/m-1s-1). Correlation and regression analysis reflected a common trend indicating that an increase in amount of plant extract led to a significant (P<0.05) decrease in drying time, water proof nature, density and viscosity but on the other hand it increased the pH of the formulation. Conclusively, the physical properties of these plant formulations compare favourably with standard commercial ink brands.

Abstract: This study investigated the impact of growth media on the early growth of Pterocarpus santalinoides. The experiment was set up in a completely randomized design involving three replicates. Ten (10) seedlings per sowing media including topsoil, sharp sand, topsoil and sharp sand, topsoil and sawdust, and topsoil and poultry droppings were selected and transplanted into a polybag. Growth parameters (seedling height, collar diameter and leaf number) were determined and subjected to analysis of variance. Seedlings of P. santalinoides displayed significant differences (p ≤ 0.05) in height at month 1, in collar diameter at month 2 to 4 and 6 and in leaf number at month 3 and non-significant differences (p > 0.05) in height at month 2 to 12. In collar diameter at months 1, 5 and 7 to 12 and in leaf number at months 1and 2 and 4 to 12.Average seedling height from month 1 to 12 was highest in topsoil and lowest in mixture of topsoil and sharp-sand. Average collar diameter from month 1 to 12 was highest in topsoil and lowest in mixture of topsoil and poultry dung. Average leaf production from month 1 to 12 was highest in topsoil and lowest in mixture of topsoil and sawdust and mixture of topsoil and poultry dung. Survival rate was 90% in seedlings grown in topsoil and sharp-sand mixture and 100% in topsoil, topsoil and sawdust mixture, and topsoil and poultry dung mixture. Topsoil was observed to be the most suitable growth media for raising seedlings of P. santalinoides and is therefore recommended for growth of the species.

Abstract: Over the years, structural changes in pig production has led to obvious increase in scale of   production through the establishment of medium to large industrial sized pig farms. This has given rise to monumental increase in pig dung with attendant waste management challenges that need to be addressed. This study analyzed the effects of fundamental changes in pig management and how they affect manure fructification practices. Data were collected from three hundred pig farmers in Ifo local Government Area using well-structured questionnaire. These data were analysed using mean, standard deviation and multinomial logit regression. The results showed that the proportion of pig production has an important effect on how farmers device use for the ensuing pig dung or manure. Clearly, the results from descriptive statistics and multinomial estimation show that smaller holders are more likely to use pig manure in their farms, while larger scale pig producers have higher probability of trading the manure or find other ways to deal with it. Unleashing agnate environmental policies that stimulate manure treatment prescriptions is advocated.

Abstract: Cotton has moderately tolerance against salinity and it can tolerate up to 7.7 dS m−1, but salinity decrease the growth rate and fiber production. The osmotic stress, ionic toxicity, essential nutrient deficiency, reduced photosynthetic rates and oxidative stress in cotton plants are associated with salinity stress which affects water uptake. Salt stress significantly inhibits the growth, development, and productivity of cotton because of osmotic, ionic, and oxidative stresses. It also decreased the seedling emergence, vegetative and reproductive growth which reduce the yield at mild to high salt stress. The moderate and higher level of soil salinity also cause reduction in seedling emergence, decrease vegetative and reproductive growth and ultimately decrease the cotton yield and fiber quality. This crop is very sensitive to salinity at germination and seedling stage. Salt stress adversely affects the biomass production and ultimately brings about decrease in seed cotton yield. Depressed activities of metabolic enzymes viz: acidic invertase, alkaline invertase and sucrose phophate synthase leads to fiber quality deterioration in salinity. With the emergence of functional and comparative genomics, transgenic techniques have become a major part of modern research. It is suggested that future research may be carried out with the combination of conventional and advance molecular technology to develop salt tolerant cultivars.

Abstract: Background: Ultrasonography is a useful method for determining the status of early pregnancy. First trimester sonography is useful for dating, assessing a number of gestation, establishing location, and even detecting some early Malformation. In addition to documenting normal development, ultrasonography has high sensitivity for showing abnormalities of the gestational sac, yolk sac, and embryo that predict poor outcome. The purpose of the present study was to examine whether yolk sac diameter and early embryonic heart rate could serve as prognostic factors in evaluating pregnancy outcome. Methods: This prospective cross sectional study that carried out on 150 patients in Al-Azhar university hospital Assuit, outpatient clinic and obstetrics and gynecology department in un complicated singleton pregnancy. Detailed history was taken to rule out medical & surgical complication which can affect our study. General and physical examination was done. For each sonographic parameter, nomograms were created; were calculated for each measurement, and the values were compared between miscarriage and ongoing pregnancy groups. Results: Abortion rate in relation to the total number of the study was (9.7%) Mean value of yolk sac among miscarriage Group was smaller than ongoing pregnancy groups. Mean value of gestational sac among miscarriage group was smaller than ongoing pregnancy groups. Mean value of embryonic heart rate among miscarriage group was smaller than ongoing pregnancy groups. These smaller values of yolk sac, gestational sac and embryonic heart rate are predictors for miscarriage.

Conclusion: Smaller values of yolk sac, gestational sac and embryonic heart rate are prognostic factors for miscarriage.
