Biomass production and biochemical composition of Chlorella vulgaris grown in Net-House Photobioreactor (NHPBR) using sugarcane press mud waste

The present Net-House Photobioreactor (NHPBR), which has a final capacity of 500 liters, was developed for the purpose of cultivating the Chlorella vulgaris by employing vinasse waste as a source of organic carbon and certain minerals in an effort to lower the cost of production. The growth unit consisted of one reservoir tank carrying 4 Plexi-glass ponds. For each plate, growth and biochemical composition were routinely evaluated to assess the precipitation and growth. Our data revealed no differences in the biomass and chemical constituents in the running algal slurry. However, differences were observed in the precipitated algal biomass for each plate, with the reservoir (CR) and the lower plate (P1) forming the greatest precipitation in terms of dry weight and mat thickness, respectively. The biochemical composition of the harvested biomass was 51.0% crude protein, 13.4% total carbohydrates, 12.1% lipids, and 7.2% ash

Hologenome analysis of two marine sponges with different microbiomes

Background:Sponges (Porifera) harbor distinct microbial consortia within their mesohyl interior. We herein analysed the hologenomes of Stylissa carteri and Xestospongia testudinaria, which notably differ in their microbiome content.Results:Our analysis revealed that S. carteri has an expanded repertoire of immunological domains, specifically Scavenger Receptor Cysteine-Rich (SRCR)-like domains, compared to X. testudinaria. On the microbial side, metatranscriptome analyses revealed an overrepresentation of potential symbiosis-related domains in X. testudinaria.Conclusions:Our findings provide genomic insights into the molecular mechanisms underlying host-symbiont coevolution and may serve as a roadmap for future hologenome analyses.publishe

Employment Relationship in Terms of the Optimization of Wage Costs

The Bachelor’s thesis deals with the issues of labour-law relations, above all their establishment. The aim of the paper is to propose a solution to the problem concerning lack of applicants for the work positions offered, or rather optimization of the number of employees working for an employer in relation to the optimization of labour costs. Based on the results of a conducted analysis and survey, the employer is recommended taking measures which would optimize the number of employees as well as the labour costs
