“…Microorganisms represent the richest repertoire in chemistry and molecular diversity in nature, providing the basis for ecological processes such as biogeochemical cycles (PANIZZON et al, 2015) and are fundamental for soil quality because they can alter the physico-chemical characteristics of the environment, directly participating in the transformations of nitrogen and phosphorus (MASSENSSINI et al, 2014).…”

ABSTRACT:A challenge for the environmental recovery of degraded areas is the search for soil data. In this process, the microbiological parameters and soil chemicals are potential indicators of soil quality. This study aimed to evaluate soil quality based on microbiological and chemical soil attributes in different areas involving environmental recovery, sugarcane cultivation and remnants of native vegetation located in a rural private property farm in State of Mato Grosso do Sul, Brazil, in Hapludox Eutrophic soil. The microbiological (microbial biomass carbon, basal respiration, microbial quotient and metabolic quotient) and chemical parameters (organic matter, carbon, pH, cationic exchange capacity, sum of bases, potassium, phosphorus, magnesium, calcium, saturation base and potential acidity) were assessed. Data were assessed by variance and multivariate analysis (Principal Component Analysis and cluster analysis). Overall, the results showed highest alteration in the chemical and microbiological characteristics of the soil in sugarcane cultivation area in comparison with other areas. Considering the studied recovery areas, REC1, REC5 and REC7 show chemical and microbiological conditions with most similarity to native vegetation. Despite the short period of the resilience enhancement of environmental recovery areas, the development of vegetation cover and establishment of the microbial community were determined to be important factors for improving soil quality and environmental recovery in several of the areas studied. ATRIBUTOS QUÍMICOS E MICROBIOLÓGICOS SOB DIFERENTES COBERTURAS DE SOLORESUMO: Um desafio para a recuperação ambiental de áreas degradadas é a busca de dados de solo. Neste processo, os parâmetros microbiológicos e química do solo são potenciais indicadores de qualidade do solo. Este estudo objetivou avaliar a qualidade do solo com base em atributos microbiológicos e químicos do solo em diferentes áreas, em recuperação ambiental, cultivo de cana e remanescentes de vegetação nativa, localizada em uma fazenda de propriedade privada rural no estado de Mato Grosso do Sul, Brasil, em solo Háplico Eutrófico. Os parâmetros microbiológicos (carbono da biomassa microbiana, respiração basal, quociente microbiano e quociente metabólico) e químicos (matéria orgânica, carbono, pH, capacidade de troca de cátions, soma de bases, potássio, fósforo, magnésio, cálcio, saturação por bases e acidez potencial) foram acessados. Dados foram avaliados por meio de análises de variância e multivariada (análise de agrupamentos e Análise de Componentes Principais). Em geral, os resultados mostraram maior alteração das características químicas e microbiológicas do solo na área de cultivo de cana em comparação com outras áreas. Considerando as áreas em recuperação estudadas, REC1, REC5 e REC7 mostram condições químicas e microbiológicas com maior semelhança com a vegetação nativa. Apesar do curto período do realce de resiliência das áreas de recuperação ambiental, o desenvolvimento da cobertura vegetal e o estabelecimento ...

“…Regardless of the limited knowledge, the position of science is consistent in that the diversity of microorganisms has a direct impact on the stability of different ecosystems, from water and soil, to the human body. Over the last decades, attention has been paid to the preservation of biodiversity, including microorganisms, for example, by more sustainable soil cultivation (Panizzon et al 2015). On the other hand, there is a strong position that the soil is such a huge reservoir of diverse individuals and, consequently, an inexhaustible source of functions that the environmental changes do not cause a damage to the whole ecosystem.…”

Functional Redundancy of Soil Microbiota – Does More Always Mean Better?

Abstract. The proper and healthy functioning of the soil depends largely on the microorganisms abundance, including the total number of bacteria and fungi, but also their diversity. The increase in the biodiversity also increases the functional capabilities of the ecosystem but from a certain point, a further increase in the biodiversity does not bring any new features, so the general biochemical and metabolic profile of the ecosystem remains constant. It is also suggested that the loss of one or more species does not dramatically affect the functioning of the ecosystem, because the same functions can be represented by many different species. This phenomenon is called a functional redundancy and makes the soil a very stable environment with a high buffering capabilities, more often called the "soil memory". On the other hand, some unique biochemical processes are characteristic for a small group of species, for example, nitrogen fixation or toxic compounds degradation. The loss of the specialized species may lead to the decrease of a rare genes occurrence in the soil, resulting in the loss of nutrients or the accumulation of toxins.This article presents the current findings on functional redundancy in terms of soil microorganisms and its implications to the soil functioning.

“…Due to this heterogeneous microbiota, raw artisanal cheeses acquire richer and more intense flavors than pasteurized ones, which need to be sustained. Additionally, the defense of biodiversity stimulates the production of foods that provide benefits for the consumers as stated by PANIZZON et al (2015). In this regard it is known that an increased diversity has been linked to a favorable metabolism and immune system response, while a reduced variation in microbiota has been associated with health problems (MCINTOSH, 2014).…”

Diversity of lactic acid bacteria isolated from traditional Montenegrin dairy products

et al. 2018

Traditional production of fermented dairy products in Montenegro is carried out without adding defined starter cultures. This way of production involves lactic acid bacteria (LAB) that are normally present in the raw milk and production environment. This autochthonous ("wild") fermentation microbiota represents a reservoir of unknown strains. In order to study the LAB diversity, 25 indigenous dairy products in Montenegro have been tested. Isolation was performed on microbial media M17 and MRS agar with or without supplementations under aerobic and anaerobic conditions at temperatures of 30?C, 37 ?C and 44?C. Identification of these isolates at species level was done by species-specific PCR and gene regions sequencing of representatives of each RAPD-cluster. RAPD-PCR was used to characterize the isolates at strain level. Nine Lactobacillus species, five Leuconostoc species, four Enterococcus species as well as strains of the species Lactococcus lactis, Pediococcus pentosaceus and Streptococcus thermophilus were detected. It can be concluded that a rich lactic acid bacteria diversity existed in the analyzed Montenegrin dairy products. Further examination of the isolates could lead to the development of autochthonous starter cultures that would contribute to a product that is characteristic for the geographical area and to which the local population is accustomed.
