Why do bacteria damage their hosts? After bacteria bypass the immune system, bacterial virulence enables a host to replicate and propagate within a host in part by demolishing or escaping host defenses. Bacterial pathogens possess an array of specific killer mechanisms that submit virulence and the capacity to intercept host defence mechanisms. Mechanisms of virulence are often mediated by the subversion of normal aspects of host biology. Also, recently, three novels but wide themes have emerged in the field of bacterial virulence: a bacterial killing mechanism, secretion systems and pathogenicity islands. So, pathogen changes the host function so as to support the pathogen’s survival or multiplication. Such subversion is often mediated by the specific interaction of bacterial effector molecules with host-encoded proteins and other molecules. Escherichia coli is a considerable and diverse micro alive. E. coli needs only to acquire a mix of mobile genetic elements to become a pathogen capable of causing diseases. The worldwide burden of these diseases is staggering, with hundreds of millions alive affected annually. E. coli strains have been well a bacteria model, and each uses an arsenal of virulence and toxin to subvert host cellular functions to reenforce its virulence. This review focuses on the drastic and different pathogenic mechanisms that are used by various E. coli strains.

Microalgae consist of unicellular algal species that can produce and accumulate a wide variety of biomolecules. In order to maintain a high cell density in a continuous phototrophic culture of algae, the nutrient can serve as the most important factor in enhancing cell density. In this study, the effect of different concentrations of nutrients on the cell density of microalga Nannochloropsis sp. cultured in the mega plastic box (with 50 L capacity) was investigated. Four groups of treatment with four replicates were tested: group A (including 5 g L-1 of ferric chloride, ammonium phosphate, and Urea), group B (including 10 g L-1 of ferric chloride, ammonium phosphate, and urea), group C (including 15 g L-1 of ferric chloride, ammonium phosphate, and urea), and group D (including 15 g L-1 of ferric chloride, ammonium phosphate, and urea with 40 g L-1 of cow manure). Results revealed that group C and group D achieved maximum density on day three as 86.39×106 cell mL-1 and 85.59×106 cell mL-1, respectively, which were significantly (p≤0.05) higher than the cell density of groups A (58.01×106 cell mL-1) and group B (70.67×106 cell mL-1). Additionally, the increasing specific growth rate (SGR) of Nannochloropsis sp. cultured was obtained in group D at 0.308 day-1 after the culture period. From the result of the study, it is concluded that the concentrations of 15 g L-1 ferric chloride, ammonium phosphate, and urea (group C) and 15 g L-1 ferric chloride, ammonium phosphate, and urea combined with 40 g L-1 cow manure (group D) are capable of increasing cell density growth of microalga Nannochloropsis sp. cultured in a mega plastic box. https://prensip.gen.tr/ Sanuddin et al.

微藻由单细胞藻类组成，能够产生和积累多种生物分子。为了在藻类的连续光养培养中保持较高的细胞密度，营养物可以作为提高细胞密度的最重要因素。本研究研究了不同浓度的营养物对容量为50 L的巨型塑料箱中培养的微藻纳米绿藻细胞密度的影响。试验设4组处理，共4个重复:A组(含5 g L-1氯化铁、磷酸铵和尿素)、B组(含10 g L-1氯化铁、磷酸铵和尿素)、C组(含15 g L-1氯化铁、磷酸铵和尿素)和D组(含15 g L-1氯化铁、磷酸铵和尿素加40 g L-1牛粪)。结果显示，C组和D组在第3天细胞密度最大，分别为86.39×106细胞mL-1和85.59×106细胞mL-1，显著(p≤0.05)高于A组(58.01×106细胞mL-1)和B组(70.67×106细胞mL-1)。此外，D组纳米绿藻的特定生长率(SGR)在培养期后0.308 D -1时显著提高。从研究结果来看，15 g L-1氯化铁、磷酸铵和尿素浓度(C组)和15 g L-1氯化铁、磷酸铵和尿素与40 g L-1牛粪(D组)结合能够提高微藻在巨型塑料箱中的细胞密度生长。https://prensip.gen.tr/ Sanuddin et al.(2023)自然科学学报4(1)，87-93 .链接本文
